South Gym Renovation Plan

Overview

Renovation of the South Gym into a fully functional multi-purpose space with modern AV capabilities and updated lighting. The space has an attached kitchen and serves a variety of uses:

• Weekdays: School gymnasium
• Evenings/Weekends: Youth events, weddings, funerals, breakfast/lunch/dinner events, meetings

Current State

• Lighting: Old fluorescent tube fixtures throughout the space
• AV: Existing equipment includes a MediaMatrix Xframe88 DSP with MM8802 I/O panel (being replaced by BLU-100s), Midas M32R mixer on a cart, ceiling-mounted projector with motorized screen, AMX/SVSi video path
• Integration: Currently not connected to the main church AV infrastructure

Design Principles

• Independent with facility connectivity – the South Gym audio system is self-contained and does not join the facility’s Dante network. AMX provides control and the ability to receive audio/video from the Auditorium if needed in the future.
• Flexibility – the space must quickly adapt between use cases (school gym, events, weddings, youth nights)
• Simplicity – the system should be operable by volunteers with minimal training
• Reliability – equipment should be durable and suited to a gymnasium environment

Scope

In Scope

• AV system design and installation (audio, video, control)
• Lighting upgrade (replace fluorescent tubes with a modern solution)
• Network infrastructure to support AV and future facility integration

Out of Scope

• Structural or architectural changes
• HVAC or mechanical systems

South Gym Audio Plan

Goals

• Provide clear, even audio coverage for spoken word and music playback
• Operate as an independent, self-contained audio system

Current State

The existing DSP is a MediaMatrix Xframe88 (1U) with an MM8802 I/O panel (1U). This is being replaced by two BSS BLU-100 units because:

• End of life: The Xframe88 is a legacy platform (Motorola 56002 DSPs) that is no longer supported or serviceable. Replacement parts and expertise are increasingly unavailable. (See equipment reference for specs.)
• Better AMX integration: The BLU-100 supports direct control via IP or serial, allowing AMX to recall presets, adjust levels, and select inputs natively. The Xframe88’s control interface is more limited and harder to integrate with the current AMX system.
• More capable DSP: The BLU-100 offers modern DSP processing, flexible routing, and the ability to act as the system’s mux point – accepting M32R output as an input and switching between sources under AMX control. (See equipment reference for specs.)

Architecture

The South Gym audio system has two operating modes:

• Base mode (BLU-100): For everyday use – school gym, meetings, announcements, background music for dinner events. BSS BLU-100 processors handle all audio processing and routing, controlled entirely by AMX. No operator required.
• Complex event mode (Midas M32R): For live-mixed events – weddings, funerals, youth worship, concerts, banquets with live music. The existing Midas M32R mixer is the foundation, operated by a live sound volunteer.

The BLU-100s are the always-on backbone of the system. The M32R is patched in when an event calls for full live mixing capability.

Why two systems? The BLU-100s provide preset-driven, unattended operation for everyday use, but they can’t provide the real-time fader-per-channel mixing that a live operator needs for complex events. The M32R fills that role and is an existing investment that works well – there’s no reason to replace it. (See equipment reference for M32R specs.)

Signal Path

The rack-mounted DL16 is the central physical I/O point in the system. Wireless mic receivers connect to its inputs, and amplifier feeds come from its outputs. It connects to the M32R via AES50 when the M32R is in use.

Base mode (BLU-100)

For everyday use – no operator, AMX-controlled:

1. Wireless mic receivers are split to the BLU-100 inputs
2. Arylic LP10 feeds the BLU-100 as a line-level input (background music via AirPlay 2, Spotify Connect, Bluetooth, etc. – see equipment reference)
3. BLU-100s process the audio (EQ, levels, routing) under AMX control
4. BLU-100 outputs feed the amplifiers (via MUX)
5. Amplifiers drive the speakers

The rack DL16 and M32R are not in the active signal path in this mode.

Complex event mode (M32R)

For live-mixed events – operator at the M32R:

1. Wireless mic receivers are split to the rack DL16 inputs
2. Rack DL16 sends mic audio to the M32R via AES50
3. Portable DL16 on stage sends instrument inputs to the M32R via AES50 (daisy-chained through M32R)
4. M32R operator mixes all inputs
5. M32R sends mix output back to the rack DL16 via AES50
6. Rack DL16 analog outputs feed the amplifiers (via MUX)
7. Amplifiers drive the speakers

Multiplexing (MUX)

The Peavey Pro-LITE 5.0 amps have a single combo XLR/1/4“ input per channel – they can’t accept two sources and switch between them. This means the mux must happen upstream of the amps.

Approach: BLU-100 internal routing. The M32R/DL16 output feeds into the BLU-100s as an input. The BLU-100 DSP selects between its own processing and the M32R passthrough, controlled by AMX. The BLU-100s are the single point feeding the amps in both modes.

This approach was chosen for three reasons:

1. It’s the only viable option for switching – the Pro-LITE 5.0 has a single combo XLR/1/4“ input per channel (see equipment reference), ruling out amp-level input switching. An external AMX-controlled audio switcher was ruled out as unnecessary complexity given that the BLU-100’s internal routing can handle the switching natively.
2. Equipment protection – routing the M32R output through the BLU-100s allows limiters to be applied to the M32R feed before it reaches the amplifiers. This protects the speakers and amps from damage due to operator error at the M32R (e.g., feedback, accidental hot levels).
3. Consistent output processing – regardless of which source is active, the BLU-100s can apply system EQ, delay, and zone routing to everything going to the amps.

BLU-100 to amp cabling

Balanced connections are required between the BLU-100 outputs and amp inputs. The BLU-100s are on UPS-isolated ground (via the RLNK) while the amps are on building ground (dedicated panel circuits). An unbalanced connection would allow the ground potential difference to appear as audible hum. Both devices support balanced I/O (BLU-100 balanced outputs, Pro-LITE 5.0 balanced combo XLR inputs at 20kΩ), so this is straightforward – use XLR cables, not 1/4“ TS. See Electrical Plan – Grounding for the full ground boundary analysis.

With three amps serving different roles — ceiling speakers (amp #1), subwoofers (amp #2), and floor monitors (amp #3) — each amp likely needs its own output pair from the BLU-100s. The BLU-100 DSP handles crossover, zone routing, and monitor mix processing, so the signal sent to each amp is different. This means 6 BLU-100 output channels are needed (one stereo pair per amp).

The Pro-LITE 5.0 has line-level through outputs (1/4“ jacks) that can pass signal to another amp (see equipment reference). These are useful if any two amps share the same signal, but with three distinct roles, daisy-chaining is unlikely to apply.

The amps also support parallel input mode (one input drives both channels) and selectable input function (full-range, sub, through). Parallel input mode is useful here — each amp drives two identical outputs (2 ceiling speakers, 2 subwoofers, or 2 floor monitors) from a single BLU-100 output channel, reducing the BLU-100 output count from 6 to 3.

Requirements

• Full-room coverage for spoken word (meetings, announcements, ceremonies)
• Music playback capability (background music for events, youth nights, wedding receptions)
• Wireless microphone support (handheld and lapel)
• AMX-controlled presets on the BLU-100s for unattended operation
• Ability to switch between BLU-100 base mode and M32R live mixing mode

Considerations

• Room acoustics: Gymnasiums are notoriously reverberant. Acoustic treatment or speaker selection should account for this. The room has concrete/brick walls to 10’, wood paneling above, dark green rubber gym floor, no windows, and no acoustic treatments — all hard, reflective surfaces.
• Room partitions: No operable walls, partitions, or windows. All walls are fixed.
• HVAC and reflections: No bleachers or in-room HVAC units. The air handler is external with supply/return vents into the room. Ceiling-mounted circulation fans are present. Flutter echo assessment is pending on-site measurement.
• Stage position: Fixed at the front of the room, under the projection screen / future LED display(s). Monitor/fill speaker requirements are TBD.
• Speaker coverage modeling: EASE Focus 3 (free) will be used for speaker coverage prediction — SPL distribution, frequency response, and coverage uniformity. DXF floor plans can be imported as a background reference for tracing room geometry. Speaker manufacturer GLL files provide the directivity data. This should be done once the room dimensions (from DWG files) and speaker model are known.
• Speaker placement: Ceiling-mounted or wall-mounted speakers to keep the floor clear for sports and events
• Durability: Equipment must withstand a gym environment (temperature swings, ball impacts on grilles, etc.)
• Input splitting: Microphone and input splits need to be clean and reliable. Passive mic splitters or an analog split patch may be simplest. Digital splitting (e.g., a shared stage box with dual outputs) is another option if the M32R’s stage box supports it.
• Balanced connections by default: All analog audio connections will use balanced wiring unless there is a compelling reason not to. This applies regardless of cable length – even short in-rack runs. Balanced connections reject common-mode noise and eliminate ground loop hum at ground boundary crossings (see Electrical Plan – Grounding).
• AMX control of BLU-100: AMX communicates with the BLU-100 via serial or IP to recall presets, adjust levels, and select inputs.

Equipment

Wireless Frequency Coordination

The MIPRO ACT-727a receivers cover 482-698 MHz across three switchable bands, each 72 MHz wide:

ISED Regulatory Restrictions

ISED’s Decision on the Technical, Policy and Licensing Framework for Wireless Microphones and SAB-003-17 define the following rules for the 470-698 MHz range:

Impact on the ACT-727a:

• Band 5UA (482-554 MHz): Safe. Entirely within the legal 470-608 MHz range. This is the primary operating band.
• Band 5US (554-626 MHz): Mostly safe. 554-608 MHz is legal (54 MHz). The top 18 MHz of the band crosses into restricted/prohibited territory (channel 37 at 608-614, guard band at 614-617, and prohibited auction spectrum at 617-626).
• Band 6UA (626-698 MHz): Mostly prohibited. Only 11 MHz (652-663 MHz duplex gap) is legal. The remaining 61 MHz is auctioned mobile broadband spectrum. Operating in this band risks regulatory violation and interference from/to LTE/5G base stations.

Compliance concern: The ACT-727a’s ACT auto-scan selects clear RF channels based on signal presence, not regulatory compliance. It does not know which frequencies are legally prohibited in Canada. If set to band 6UA, the auto-scan could select a frequency in the 617-652 or 663-698 MHz prohibited ranges simply because no strong signal is detected there yet. Restrict both receivers to band 5UA or 5US only. Band 6UA should not be used unless frequencies are manually set within the 652-663 MHz duplex gap and verified against ISED rules.

Edmonton Market UHF TV Stations

The following UHF broadcast stations in the Edmonton market (which includes Sherwood Park) must be avoided. Source: RabbitEars Edmonton market.

Each TV channel occupies 6 MHz. The ACT auto-scan should detect and avoid these as occupied channels. With 4 stations in band 5UA, the usable spectrum in that band is reduced from 72 MHz to ~48 MHz — still ample for 4 wireless mic channels (each needs ~200 kHz).

Multi-Receiver Coordination

The ACT-727a has 7 preset frequency groups with pre-calculated intermod-free channel sets:

For a fixed installation with 2 receivers (4 channels), preset groups are the right approach — not auto-scan. Set both receivers to the same group (e.g., Group 1) and assign different channel numbers: channels 1-2 on receiver #1, channels 3-4 on receiver #2. Since the channels within a group are pre-calculated by MIPRO to be intermod-free, they coexist cleanly. Set once during commissioning and leave it.

The auto-scan is designed for portable use in unknown RF environments. For a fixed install where all wireless is controlled, the preset groups give deterministic, repeatable results.

MIPRO also offers RCS27 software (connects via the rear RJ-11 port) for PC-based monitoring and control, and the newer RCS2.Net for network-based coordination of up to 64 channels — but both are overkill for 4 channels in a fixed install.

Cross-facility coordination with the auditorium’s wireless systems is not needed — the auditorium is a few hundred feet away through concrete/brick walls, putting any signal well below the receiver noise floor.

Recommended Operating Configuration

1. Set both receivers to band 5UA (482-554 MHz) and the same preset group. Band 5UA has the most usable legal spectrum and sits entirely within the ISED-approved 470-608 MHz range.
2. Assign channel numbers during commissioning: channels 1-2 on receiver #1, channels 3-4 on receiver #2 (within the same group). Verify selected frequencies do not land on the 4 local TV stations (RF 16, 17, 25, 27 — see table above). The preset groups should avoid these automatically, but confirm during setup.
3. Band 5US (554-626 MHz) is the secondary option if band 5UA proves unusable. Manually verify selected frequencies stay below 608 MHz.
4. Do not use band 6UA unless frequencies are manually locked to the 652-663 MHz duplex gap.

Open Questions

Room Acoustics & Speaker Design

• What are the room dimensions (length, width, ceiling height at speaker mounting points)?
• Has any acoustic measurement been done (RT60, STI), or is there a baseline reverberation estimate?
• Is there budget or structural willingness for acoustic treatment (hanging baffles, fabric panels, banners), or must the speaker design compensate for the room as-is?
• Can the ceiling structure support pendant-hung or flown speakers, or is wall mounting the only option?

• Room aspect ratio – does it favor a center cluster, a stereo pair, or a distributed grid?
• Is stereo imaging a priority for any use case, or is mono coverage uniformity more important?
• What is the maximum tolerable SPL variation across the listening area (+/-3 dB, +/-6 dB)?
• What is the target max SPL at the mix position or far seat for live music events?

• Is the space climate-controlled during off-hours, or must speakers handle temperature extremes?

Signal Path & DSP

• How will the mic/input split be handled – active buffer, or direct patching to line-level inputs? Passive transformer splitters designed for mic-level signals are not suitable (the ACT-727a outputs line level). Options include: (a) a simple Y-split of the balanced line-level XLR, (b) an active buffer/distribution amp, or (c) routing one channel’s XLR to the BLU-100 and using the mixed output for the DL16 (or vice versa).
• How many analog inputs does each BLU-100 have? Is there enough I/O across both units for all mic splits AND the M32R return feed?
• How many BLU-100 analog outputs, and which map to which amp channels? Are any spare for monitor feeds, record outputs, or future zones?
• Which DL16 outputs carry the M32R mix return to the BLU-100 vs. the amplifier feeds? Are there enough outputs for both simultaneously?
• What is the BLU-100 DSP processing chain order (gain trim, EQ, compressor, limiter)?
• What target output level (dBu) should the BLU-100 deliver to the Pro-LITE 5.0 inputs at nominal program level? What is the amp’s rated input sensitivity?
• What speaker delay values are anticipated (per-speaker or per-zone)? Does the BLU-100 have enough independent delay blocks?
• What room EQ target is planned (flat response, speech intelligibility voicing, or a blend)? Has a measurement session been planned?
• BLU-100 limiter configuration: absolute clip limiter, program limiter with release time, or both in series? What threshold?
• In M32R passthrough mode, does the signal bypass all BLU-100 DSP, or still pass through the output limiter and delay?
• What is the expected nominal output level from the DL16 when the M32R is feeding it? Is that compatible with BLU-100 input headroom?
• When AMX switches from base mode to M32R passthrough, is there a crossfade or mute during transition, or a hard switch? A hard switch could produce an audible transient.
• Can the BLU-100 limiter threshold for M32R passthrough be set independently of the base mode limiter?
• AES50 port assignment: which M32R port connects to the rack DL16 (A or B), and which to the portable DL16?
• What AES50 cable type and max run length is specified for the umbilical? Has the planned distance been confirmed within spec?
• If the portable DL16’s AES50 passes through the M32R, does a rack DL16 fault also drop the portable DL16?
• Has the end-to-end gain structure been documented for both modes (mic capsule → receiver → split → BLU-100/DL16 → DSP → amp → speaker)?
• Pro-LITE 5.0 front panel attenuation controls: set-and-forget trim or operator-accessible? What happens to gain structure if an untrained person adjusts them?
• Is there a documented level agreement for M32R operators (e.g., M32R master at 0 dBVU = X dBu into BLU-100)?
• If one BLU-100 fails, does the system lose all zones or just those assigned to that unit? Has zone assignment been designed for partial-failure resilience?
• Is there a bypass path (DL16 direct to amps) if both BLU-100s fail during a live event?
• If AMX loses communication with a BLU-100, does it hold its last preset, fall back to a safe default, or go silent?
• With 3 amps x 2 channels = 6 amp channels (or 3 if using parallel input mode), do the BLU-100s have enough analog outputs? What is the output assignment plan?
• Has cable dressing been planned to separate audio signal cables from power cables in the rack?

Wireless Microphones & Inputs

• With 4 wireless channels available (2x ACT-727a), what is the typical channel assignment for weddings (e.g., officiant + reader + musician + spare)? Is 4 sufficient, or could larger events need more?
• For youth events, what is the maximum simultaneous wireless channel count needed, and is it expected to grow?
• Are wireless instrument transmitters (guitar, bass) or IEM packs sharing the frequency pool with vocal mics?
• What antenna type is appropriate for the gym environment (omni paddle vs. directional log-periodic) given the metal ceiling structure? The ACT-727a uses 50Ω TNC connectors with DC bias for MIPRO antenna boosters.
• What is the worst-case distance from the rack closet to the farthest transmitter location? Does this exceed reliable range without remote antennas?
• Is remote antenna mounting (outside the rack closet, on a wall or ceiling) needed? Where, and what cable type/length? Note: If remote antennas are used, they must be electrically isolated from building ground (e.g., non-conductive mount or isolating bracket). The receivers are on UPS ground via the RLNK – if the antenna mount is bonded to building steel, the coax shield bridges the two ground references and creates a ground loop. See Electrical Plan – Grounding.
• Will the mic split be a labeled patch panel point for troubleshooting, or hidden in the back of the rack?
• How many simultaneous wired inputs are expected on stage at the largest event? Does the DL16’s 16-input count accommodate that?
• Are there instruments or sources requiring phantom power on the portable DL16?
• Is there a floor pocket or wall box for wired XLR drops (backup mics, DI boxes, podium mic), or do all wired sources go through the portable DL16?
• What does the M32R umbilical need to carry (network, AES50 for portable DL16, IEM returns, power)?
• How many stereo IEM mixes are expected, and do IEM transmitters need power and frequency coordination alongside vocal mics?
• What is the planned maximum umbilical length? Has it been verified against AES50 spec (100m for Cat 5e) including the daisy-chain to the portable DL16?
• Does the umbilical floor drop need to accommodate the M32R cart on either side of the room, or is a single fixed drop sufficient?
• What is the battery management plan for wireless mics (rechargeable vs. disposable, charger location)?
• For multi-hour events, who monitors receiver battery status and initiates swaps?
• If rechargeable, does the charge cycle fit back-to-back event scheduling (afternoon rehearsal → evening ceremony)?

Amplifiers & Speaker Wiring

• How many discrete speaker zones with independent level control are needed?
• Will all three amps be used simultaneously in all presets, or are the sub and monitor amps only active for certain event types?
• If the subwoofer and/or floor monitor outputs are removed (both TBD), what happens to the freed amp(s) — repurposed for additional speaker zones, kept as spares, or removed?
• Will the crossover for subwoofers be in the BLU-100 DSP or the amp’s “sub” input function? What crossover frequency and slope?
• What is the minimum speaker impedance the system will present? Confirm amps won’t go below 2Ω under any wiring configuration.
• At what impedance will the system most likely operate? This determines actual per-channel power and heat output.
• Has a room SPL calculation confirmed whether 15,000W of amplification (3x Pro-LITE 5.0) is appropriately sized, or significantly oversized?
• What is the expected speaker sensitivity (dB SPL/1W/1m)?
• If amps are oversized, is there a risk of front panel attenuation at very low levels reducing control resolution?
• What is the distance from the rack closet to the farthest speaker? Has wire gauge been calculated for run length and load impedance to maintain damping factor?
• Speaker wire type: in conduit, plenum-rated, or CL2/CL3? What does local code require for in-ceiling runs?
• Are speaker wires home-run (one per speaker back to rack) or daisy-chained within zones? Daisy-chaining changes the impedance the amp sees.
• Speakon pin assignments: consistent between amp output and speaker ends (NL4 1+/1- vs. 2+/2-)?
• Field-installed Speakon connectors at junction boxes near speakers – who terminates, what is the testing process?
• What is the BLU-100’s maximum analog output level (dBu) vs. the Pro-LITE 5.0’s input sensitivity for full power?
• Critical: do the Pro-LITE 5.0 through outputs carry pre-attenuation or post-attenuation signal? This determines whether amp #2’s input level is independent of amp #1’s attenuation setting.
• Is the BLU-100 limiter threshold set relative to the amp’s clip point or the speaker’s power handling?
• What is the power-on sequencing plan for amps vs. BLU-100s? Can RLNK enforce sequence for RLNK devices, and what about the amps on dedicated circuits?
• Is there AMX monitoring of amp fault conditions (DC fault, thermal protection), or will faults only be discovered when audio stops?

South Gym Video Display Plan

Goals

• Provide video display capability for presentations, lyrics, announcements, and event content

Current State

• Projector: Ceiling-mounted projector, currently in place
• Screen: Motorized projection screen with dry contact control (raise/lower)
• Video path: AMX/SVSi encoder-decoder pair provides the video feed to the projector. The SVSi path has been tested and confirmed functional at 1080p – already in use for digital signage and live feed distribution around the facility

Resolution

The video system will run at 1080p for both the near-term projector setup and the long-term LED display(s).

Near-Term Plan

Integrate the existing projector and motorized screen into the AMX control system:

• AMX controls the SVSi video routing (already in place)
• AMX controls the motorized screen via dry contact relay (raise/lower). The screen uses limit switches and stops automatically at full raise/lower positions. Control is open-loop – AMX sends raise/lower and assumes it worked; there is no position feedback. No interlock between screen and projector is needed (AMX does not wait for the screen to fully lower before activating the projector). The relay module depends on the wiring approach: AMX REL8 (several available) if low-voltage wire is run to the screen, or Global Caché IP2CC-P PoE contact closure if Ethernet is run instead – the choice is tied to the relay wiring path (still an open question). Dry contacts carry only low-voltage signaling current, so any AMX relay handles the screen’s contact rating. On system-off, the screen raises immediately with no sequencing dependency on projector cool-down.
• Projector power on/off via AMX RS-232 through the SVSi decoder at the projector location. Raw serial commands are stored in the decoder and triggered by AMX via sendser (N1000/N2000 API reference) – no AMX driver module required. No separate control cable run to the rack is needed. There is no mechanism to detect a failed power-off command via sendser, so projector power-off acknowledgment is not handled.
• A “Presentation” AMX preset will combine a dimmed lighting scene with projector/screen activation. Exact dimming levels are TBD based on projector brightness vs. ambient light.

Why keep the projector for now? The projector and SVSi path are already installed and functional. Integrating them into AMX control requires no new hardware purchases – just programming. This provides a working video system immediately while the LED display decision is evaluated without time pressure.

SVSi Video Distribution

The SVSi system uses dedicated VLAN 25 on the M4250 switch with IGMP multicast for publish/subscribe stream routing. All local encoders and decoders are on the same switch. Video may occasionally be routed into or out of the room via this VLAN (e.g., auditorium overflow). End-to-end latency is 10 ms unscaled or approximately 17 ms with scaling at 60 fps (see equipment reference).

SVSi card models and locations:

• Cage cards (-C variants, in the AMX cage): 2x NMX-DEC-N1222A-C decoder (LED wall feeds to VX4S units), 2x NMX-ENC-N1122A-C encoder (rack PC and ClickShare), 1x AMX N4321 audio transceiver (audio-only streams from around the building)
• Standalone units: NMX-ENC-N1115-WP wall-plate encoder (back wall, PoE) and NMX-DEC-N1222A decoder (ceiling at projector, PoE – near-term only)
• Frame: 6-slot NMX-ACC-N9206 housing the cage cards, with 1 slot spare

EDID and stream switching: The default SVSi encoder EDID should negotiate 1080p with any modern source device. If issues arise, values from a 1080p EDID emulator can be copied to lock the encoder to a single resolution – verify during commissioning. When AMX switches the SVSi stream subscription on a decoder, the transition is a quick cut (similar to changing a TV channel). For Option B, each decoder receives a separate switching command from AMX with no timing dependency; a brief tear is possible during simultaneous switches but is not a concern.

Overflow feed: An auditorium overflow feed is available via the ross-01 encoder, already on the SVSi network (VLAN 25). This is a rare use case. Switching to or from the overflow feed behaves like any other SVSi stream subscription change – a brief glitch is possible but not a concern.

Loss-of-signal detection: Encoders use AMX HostPlay to display “no device connected to $ENCODER_NAME” when no source is detected (matching the existing facility pattern). Decoders display a similar message if their subscribed stream is not found on the network. VX4S input loss detection is not needed – any upstream issue will be caught by the encoder or decoder messages.

Long-Term Plan

Replace the projector and screen with LED display(s). Two options under consideration:

Option A: Single Large LED Wall

One larger LED wall as the primary display.

Pros:

• Single focal point – clean sight lines
• High brightness, visible in full gym lighting
• No ambient light concerns (unlike projector)
• No motorized screen to maintain

Cons:

• Higher cost for a single large display
• Fixed position – placement needs to work for all use cases
• If it fails, there’s no backup display

Option B: Two Smaller LED Panels

Two smaller LED panels, likely positioned to serve different areas or viewing angles.

Pros:

• Better coverage for a wide room – multiple sight lines
• Redundancy – one can fail without losing all video
• Potentially easier to mount depending on wall structure
• Could display different content simultaneously (e.g., lyrics + event info)

Cons:

• More complex video routing (need to feed two displays)
• Two sets of mounting hardware and cabling
• Content management is more involved if showing different sources

Two NovaStar VX4S video processors are available to be repurposed for the LED wall (see equipment reference). Each VX4S drives one display – using two to drive a single wall can cause sync issues between the processors. Each VX4S receives its feed from an SVSi decoder (HDMI output) directly to the VX4S (HDMI input). The decoder subscribes to any encoder on the SVSi network (VLAN 25) under AMX control.

• Option A (single wall): One VX4S + one SVSi decoder. Second VX4S is a spare.
• Option B (two panels): Both panels are identical in size and pixel pitch. One VX4S + one SVSi decoder per panel. AMX controls each decoder independently – same content (both subscribe to one encoder) or different content (each subscribes to a different encoder). If one panel fails mid-event, there is no automatic AMX fallback to reroute both feeds – the system simply operates with the remaining panel.

VX4S control: The VX4S accepts up to 1920x1200 @ 60Hz input (1080p60 confirmed). AMX controls the VX4S via TCP on port 5200 using a hex command protocol – a connection/handshake command is required before other commands are accepted. No AMX module exists; custom implementation is needed (straightforward hex-over-TCP). Protocol PDF available from NovaStar. The only parameter AMX needs to control is brightness (input selection is not needed since only the SVSi decoder is connected, and color/other parameters are not required). All VX4S settings persist across power cycles except brightness, which AMX should restore on every startup. The VX4S can generate test patterns independently of its input, but test patterns would more likely be generated in software (e.g., ProPresenter).

Environmental considerations: The gym environment poses a high ball-impact risk. LED panels must be specced for impact resistance, and a polycarbonate overlay may be needed depending on the manufacturer’s impact rating. Temperature and moisture are not concerns – the space is indoor and climate-controlled, and floor cleaning does not involve pressure washing or hosing.

Near-term staging and transition: The VX4S units stay in storage until an LED wall is installed – they are not racked during the projector phase. Conduit for the LED wall will be run during the initial renovation to avoid retrofitting later. When transitioning from the projector to the LED wall: run Ethernet from the VX4S units to the LED wall position (through the pre-run conduit), remove the ceiling-mounted SVSi decoder at the projector, install one or two SVSi decoder cards in the rack with HDMI out directly to the VX4S inputs, and let AMX routing handle the rest via SVSi stream subscriptions.

The LED display decision does not need to be made now. The near-term projector setup will serve while this is evaluated.

Digital Scoreboard

Once the LED wall is in place, it will also serve as a digital scoreboard for school gym use. This eliminates the need for a separate physical scoreboard and allows the display to switch between scoreboard, lyrics, presentations, and other content via AMX presets.

• What scoreboard software or system will generate the scoreboard graphics?
• What sports need to be supported (basketball, volleyball, badminton, etc.) and what scoring layouts are required?
• What device runs the scoreboard application – a dedicated media player, the ProPresenter machine, or a separate laptop?
• Does the scoreboard need to be operator-controlled from courtside (e.g., a tablet or wireless controller), or from a fixed location?

Equipment

Content Sources

Presenter Inputs

• Wired: AMX NMX-ENC-N1115-WP wall-plate encoder at the back of the room. Provides HDMI, VGA, and DVI-D/DP++ via passive adapter. This is the wired fallback – note that N1115-WP audio is known to be flaky, so use ClickShare or a separate audio path when audio quality matters. No additional floor boxes or other input locations are planned.
• Wireless: Barco ClickShare (CX-20 or similar). Supports Mac and Windows. HDMI output feeds a dedicated SVSi encoder card in the cage. The ClickShare base station needs a network drop and RLNK power.

Primary Content Tools

• ProPresenter is the default content tool, running on the rack PC (Mac mini). The operator needs a monitor for the rack PC – mechanism TBD. ProPresenter is always operator-managed independently; AMX presets do not trigger anything in ProPresenter.
• Arylic LP10 network streamer handles casual audio playback (warmups, youth events) via AirPlay 2, Google Cast, Spotify Connect, and Bluetooth. Line out feeds the BLU-100 as an audio input. No standalone video media player is needed – the rack PC handles video for larger events.
• The system is powered off when unattended; no content plays without an operator present.
• There are no plans for IMAG (live camera feed) at this time.

Audio Routing

Audio follows the video path automatically. The SVSi path carries HDMI audio alongside video – audio extraction happens at the decoder side, not the input side. The NMX-DEC-N1222A outputs 8-channel PCM via HDMI and stereo analog (balanced/unbalanced) on Phoenix connectors. The decoder extracts the embedded audio and feeds BLU-100 directly; no separate routing step or operator action is needed.

For Option B (two LED panels), both decoders need audio extraction capability so either feed can be sent to the audio system.

Source Selection and Routing

Only one simultaneous video source is active at a time. AMX presets default to the rack PC as the video source; manual source selection is always available on the touch panel.

External feeds: An auditorium overflow feed is available via ross-01 on the SVSi network (see SVSi Video Distribution). Streaming services (movie days, etc.) are handled by the rack PC with a browser. No cable, satellite, or other external feed is needed.

Resolution handling: Non-standard resolutions are not a concern. Wireless protocols (ClickShare, AirPlay, Miracast) negotiate 1080p. The wall-plate encoder EDID enforces 1080p on wired sources. If a non-standard resolution does get through, the SVSi encoder can scale it (adds approximately 7 ms).

Use-Case Workflows

• Weddings/funerals (family slideshows): Bring a laptop and connect via the N1115-WP wall plate or ClickShare, or bring content on USB and plug into the rack PC.
• School weekday use (teachers): Audio-only via LP10 (AirPlay, Bluetooth, Spotify Connect). Video+audio via ClickShare (native AirPlay/Miracast – supports laptops, iPads, Chromebooks without extra hardware). Wired fallback via N1115-WP wall plate.
• Youth events: Audio via LP10. No live camera feed (IMAG) planned.

Open Questions

Projector & Screen (Near-Term)

• What is the make, model, lumens, native resolution, and remaining lamp life of the existing projector?
• What is the projector’s warm-up and cool-down time? Does it enforce a mandatory cool-down period before power can be cycled again?
• Does the projector have an auto-wake feature that could conflict with AMX power sequencing?
• What is the measured throw distance from the projector lens to the screen, and does the current image fill the screen properly?
• At what height does the bottom edge of the screen sit when lowered? Do audience members at the back have an unobstructed sightline?
• Is there a horizontal offset between projector and screen requiring keystone correction?
• What is the anticipated lux level at the screen surface with the new lighting at full output? Is the projector bright enough for a legible image with house lights on?
• What is the relay wiring path from the rack to the screen motor controller? Two options under consideration: (1) PoE-based contact closure device mounted in the ceiling near the screen, controlled via Ethernet, or (2) low-voltage wire run from a relay in the rack up to the screen. Either way, conduit is needed.

LED Wall (Long-Term)

• What are the minimum and maximum viewing distances from each candidate mounting wall to the nearest and farthest spectators?
• What pixel pitch is required to avoid visible pixel structure at those distances, and does that pitch at the intended physical size produce a native 1080p resolution?
• What physical dimensions (width x height) are under consideration for Option A (single wall)?
• For Option B, what dimensions per panel? Does each individually reach 1080p or will the VX4S scale?
• Is there a minimum screen height requirement for sightline clearance above floor-level obstructions (bleachers, scoreboards, exit signage)?
• What is the wall construction at each candidate mounting location (masonry, steel stud, wood frame)? Has structural capacity been confirmed?
• What is the anticipated total weight of panels plus mounting structure? Does the building require a stamped structural analysis?
• Is there sufficient ceiling clearance above the panel for the mounting frame? Any conflicts with joists, HVAC, catwalks?
• How far is each candidate wall from the new electrical panel? What is the conduit routing path including fire-rated penetrations?
• What is the peak power draw per m² at max brightness, and does the total load fit on a single circuit or require multiple at the display location?
• Are LED panel power supplies internal to the panels or external rack-mounted?
• What signal protocol does the VX4S use to drive the panels (Ethernet, fiber, proprietary)? What is the max cable run length?
• What is the physical cable distance from the rack to each candidate wall? Does it exceed the VX4S transmission limit?
• How many data cables does the VX4S require for the intended panel array? Is there conduit capacity at the wall?
• Does the VX4S receive a single composited 1080p signal or multiple layers?
• What system generates the final 1080p frame (ProPresenter, media player, laptop)?
• For Option B: who decides whether panels show the same or different content? Per-event config on touch panel, or fixed mode?
• Is there a live camera feed requirement (IMAG, scoreboard camera)?
• Are the panels front-serviceable or rear-serviceable? If rear, what clearance is needed behind the array?
• What is the manufacturer’s recommended spare module inventory, and where will spares be stored?
• Does the manufacturer provide on-site warranty service? Expected response time?
• What is the ambient illuminance at the display wall with house lights on? Is panel brightness sufficient for acceptable contrast?
• What is the horizontal viewing angle, and does it serve spectators at extreme lateral positions?
• What is the expected exposure to dust, debris, or humidity from gym activities?

Content Sources & User Connectivity

• How will the operator view/control the rack PC? (Monitor in rack closet, KVM extender to a remote location, VNC/remote desktop, etc.)

South Gym Control Plan

Goals

• Provide a fully AMX-controlled multi-purpose room
• Keep day-to-day operation simple for volunteers via presets

Requirements

• Single, simple control interface for volunteers
• Presets for common scenarios (e.g., “School Gym,” “Wedding,” “Youth Night,” “Dinner Event,” “Presentation”)
• Power on/off sequencing to protect equipment

Considerations

• The control interface is an AMX MXD-1000-P 10.1“ Modero X wall-mount touch panel — the same model used successfully in previous installations. See equipment reference.
• AMX is the primary controller: AMX manages the BLU-100 processors directly – recalling presets, adjusting volume, and selecting inputs (see equipment reference). Day-to-day operation is handled through AMX presets on a touch panel (e.g., “School Gym,” “Wedding,” “Youth Night,” “Dinner Event”).
• M32R override: When the M32R is in use for a complex event, AMX switches the BLU-100 routing to pass through the M32R output to the amps (see audio plan for details). The M32R operator manages the mix; AMX handles the system-level routing.
• Presets are a starting point: After recalling a preset, operators can adjust individual parameters (volume, lighting level, etc.) from the touch panel. Adjustments are temporary and reset on the next preset recall. On the Paradigm side, individual zone levels can be overridden via PSAP after a preset recall.
• No time-based scheduling: There is no current requirement for scheduled preset transitions. The NX-4200 already uses NTP, so the capability exists if needed later.

Why use the existing facility AMX processor? The facility’s AMX NX-4200 (FG2106-04) can control the South Gym over the network via the fiber uplink, avoiding a dedicated processor purchase and keeping all AMX programming centralized. The NX-4200 has a 1600 MIPS processor, 1 GB RAM, and 8 GB storage – designed for large campus-scale installations with dozens of rooms. The South Gym’s ~8 IP devices is a trivial load relative to its capacity. Its LAN port connects to the facility network, giving it IP access to all South Gym devices (BLU-100s, SVSi, RLNK, VX4S, N4321) through the M4250 switch. See equipment reference for full specs.

Serial device limitation: The NX-4200’s 8 physical serial ports are in the IT room, not the South Gym. The ETC Paradigm ACP requires RS-232, so an AMX EXB-COM2 (FG2100-22) ICSLan serial expansion module will be placed in the South Gym rack on VLAN 21. The NX-4200 reaches it over the network — this is a proven approach used in other facility installations. The serial link runs at 9600 baud, 8N1, no handshake. The Paradigm uses the Paradigm Station Access Protocol (PSAP) – CR-terminated ASCII commands for preset recall, zone override, and status queries. Unlike the DFD 2322DMX, the Paradigm does not have a built-in heartbeat; AMX must implement a poll-based watchdog (periodic PSAP status queries) to detect a dead serial link. A single RS-232 connection on EXB-COM2 port 1 controls both the gymnasium layer (sACN to Response 0-10V Gateway) and event layer (DMX512 to SmartPacks). See equipment reference.

AMX Responsibilities

Device-specific integration notes:

• ClickShare: AMX does not directly control the ClickShare unit. It constantly outputs to its SVSi encoder when powered on. AMX’s role is limited to RLNK power sequencing and SVSi routing — the user selects ClickShare as a video source from the touch panel to route it to the projector or LED wall.
• LP10 (AirPlay/Bluetooth receiver): AMX does not directly control the LP10. It is user-operated (AirPlay/Bluetooth). AMX’s role is limited to RLNK power and BLU-100 input routing — the user selects the LP10 as an audio source from the touch panel to unmute it on the BLU-100.
• Audio source selection: AMX allows the operator to select which audio source(s) are active from the touch panel. Multiple sources can be mixed simultaneously (e.g., wireless mics + LP10), but AMX enforces sensible restrictions (e.g., wireless mics and M32R cannot be active at the same time, since the M32R has its own mic inputs).

Device Status Monitoring

AMX polls key devices and displays their status on the touch panel. This gives operators visibility into system health without needing to check individual devices.

• SVSi encoders: Source connected / no source (complements the HostPlay on-screen message)
• SVSi decoders: Stream subscription active / stream not found on network
• VX4S (long-term): Online / offline, brightness level
• ETC Paradigm ACP: Poll-based watchdog via periodic PSAP status queries (the Paradigm does not have a built-in heartbeat like the DFD 2322DMX). AMX sends a status query at a regular interval and flags a fault if no response is received within the timeout window.
• RLNK: Not monitored — the RLNK units in use don’t support overcurrent protection or external status polling.

This is a programming task – no additional hardware required. The SVSi API already supports status queries, and the VX4S responds to TCP polling on port 5200. Back-end device health monitoring is handled by existing facility infrastructure: Prometheus via SNMP for switch statistics and Uptime Kuma for device ping monitoring. AMX touch panel monitoring is limited to operator-facing status (SVSi and VX4S).

Error handling: The current facility behavior for command failures is silent failure. Improved error handling (retry logic, touch panel alerts) would be desirable but is limited by the NX controller’s programming capabilities. AMX’s newer Muse controller platform would simplify this, but it is not in scope for this project.

Failure & Fallback

The AMX processor and fiber uplink are a known single point of failure. If either fails, the touch panel becomes non-functional and devices hold their last state. A Raspberry Pi in the South Gym rack running Bitfocus Companion provides a fallback web UI capable of controlling all room gear independently of AMX. WiFi would be down if the fiber link fails, but a laptop can be plugged directly into the local M4250 switch to access Companion.

Component failure impact:

• Primary BLU-100 failure: All audio processing is lost — no audio works. The second BLU-100 is for additional I/O only; if it fails, only the I/O routed through it is lost.
• BLU-100 communication loss: The BLU-100 holds its last received settings.
• M4250 switch failure: Audio continues to work (BLU-100 holds last settings, analog paths unaffected), but SVSi-routed audio/video is lost. RLNK units retain their last state but can’t be further controlled. The touch panel loses power (PoE). The Paradigm ACP holds both its last sACN and DMX output; the Response 0-10V Gateway also holds its last received sACN values (both lighting layers hold state). Button stations continue working independently of the network. Event presets are available from a button station if configured.
• Paradigm ACP (lighting): Stores presets in non-volatile memory. Gymnasium layer: button stations outside the rack closet work independently of AMX and the network. Event layer: presets can be recalled from button stations if event presets are assigned to a station.

Future: Auditorium Feed Routing

The infrastructure supports routing audio and video from the Auditorium to the South Gym via AMX/SVSi if overflow capability is needed in the future. This is not a near-term requirement.

Open Questions

Preset Design

Deferred until the equipment list and usage needs are finalized.

• Can a complete preset-by-subsystem matrix be defined? For each named preset (“School Gym,” “Wedding,” “Youth Night,” “Dinner Event,” “Presentation,” “Cleanup,” “Off”), what is the expected state of: audio (BLU-100 routing, volume, input), video (source, projector power, screen position), lighting (DMX scene), and power (which RLNK outlets are on)? Currently no single document maps a preset name to its complete multi-subsystem behavior. The preset names in control.md (5 names) do not match lighting.md (6 names – adds “Cleanup” and “Off,” omits “Presentation”).
• How many presets will be stored in the BLU-100s, and what parameters does each preset control (input routing matrix, EQ, levels, limiter thresholds, zone assignments)? Are presets recalled as monolithic snapshots, or can individual parameters be adjusted independently (e.g., volume up/down within a preset)? Either zero or two — possibly one for standalone operation and one for M32R integration, or a single fixed setup with no presets at all. TBD.

Power Sequencing

• What is the exact power-on and power-off sequence for the 9 RLNK outlets, and what are the inter-step delays? rack.md documents the outlet allocation but has no sequencing column.
• Since the amps are on dedicated circuits (not RLNK), how are they powered on and off? Are they left permanently energized? If so, is that acceptable from a power and equipment longevity perspective? If they need to be switched, what mechanism is used (manual breaker, a second RLNK or relay, a smart outlet)? Currently control.md does not mention the amps and rack.md has no mechanism to control their power.
• What does “system off” mean operationally? (a) All RLNK outlets off, amps left on dedicated circuits, lights off via DMX, projector off, screen raised? (b) Everything fully de-energized including amps (requiring someone to throw breakers)? (c) A “standby” state where infrastructure stays powered and only output devices are off?
• Does the rack PC (Mac mini) need a graceful shutdown signal before RLNK power is removed? If so, does AMX send a network shutdown command (e.g., SSH) before killing power on outlet 7? (rack.md flags this as an open question.)

Subsystem Sequencing & Coordination

Deferred until the equipment list and usage needs are finalized.

• When a user taps a preset on the touch panel, in what order does AMX issue commands to subsystems? For example: (1) lighting fades to scene, (2) audio switches to preset, (3) projector powers on, (4) screen lowers. Are there timing dependencies (e.g., lighting must reach dimmed state before projector image is visible)? (lighting.md explicitly flags this as unanswered.)
• When AMX switches the BLU-100 routing from base mode to M32R passthrough, what is the exact BLU-100 command or preset recall? Is there a confirmation/feedback mechanism so AMX knows the switch completed successfully? What is displayed on the touch panel during and after the switch?
• Can the system transition from M32R mode back to base mode (or vice versa) during an event without an audible interruption? audio.md asks whether there is a crossfade or mute during MUX transitions – what is the defined behavior?
• How does AMX know the M32R is connected and ready? Is there a network presence check (M32R IP appears on the VLAN), a manual “M32R Mode” button on the touch panel, or automatic detection? What happens if an operator enables M32R mode but the M32R is not physically connected?
• When the “Presentation” preset is recalled, what is the default video source (rack PC, ClickShare, or wall plate encoder)? video.md states “Presets default to the rack PC.” But for presentations, a guest may expect ClickShare. Does the system support split audio/video sourcing (e.g., AirPlay audio via LP10 + ClickShare video)?

Video & Projector Control

• The VX4S defaults are documented as “all settings persist except brightness, which AMX should restore on every startup” (video.md). What is the target brightness value? Does it vary by preset? To be decided after LED wall installation. The VX4S can store a default power-on brightness persistently, so AMX restoration may not be needed.
• What are the exact RS-232 command strings for projector power on, power off, and status query (stored in the SVSi decoder via sendser)? The projector make/model is unknown (video.md open question), so the serial protocol is also unknown. The programmer is blocked until this is resolved.
• What is the physical relay device for the motorized screen dry contact? video.md lists two options (AMX REL8 via low-voltage wire, or Global Cache IP2CC-P via PoE Ethernet) but the decision is not made. Neither option appears in the networking port table, rack layout, or electrical plan. TBD — trade-offs to both approaches.

Touch Panel & User Experience

Deferred until the equipment list and usage needs are finalized.

• Where will the touch panel(s) be mounted? Near the main entrance? Near the stage/front area? Near the rack closet? Multiple locations?
• What pages/screens will the touch panel display? A minimum: (a) home page with preset buttons, (b) volume adjustment, (c) source selection, (d) status/diagnostics. Is that sufficient, or do stakeholders need more granular control (individual zone levels, individual lighting zones, per-device power)?
• What volume control is exposed on the touch panel? Single master volume for the entire room, per-zone volume, or per-source volume? What are the minimum and maximum bounds?
• Can a step-by-step operator workflow be documented for each event type? (e.g., Wedding: arrive 2 hours early, tap “Wedding,” connect M32R via umbilical, tap “M32R Mode,” sound check, etc.) The control plan defines what the system can do but not how operators use it.
• Is there a requirement for printed or laminated quick-reference guides near the touch panel? Who is responsible for ongoing volunteer training as volunteers rotate?

Device Status Monitoring

• For SVSi status, how is it displayed on the touch panel? Simple green/red indicator, or device name + specific error? What is the polling interval? What happens if polling itself fails? Deferred until touch panel UI design.

Failure & Fallback

• Should a button station near the gymnasium entrance include event layer preset buttons (e.g., “Wedding,” “Dinner Event”) for non-technical fallback when AMX is unavailable?

Scheduling & Automation

• Is there a requirement for auto-off after inactivity (occupancy sensing)? Almost certainly not, but to be confirmed.

Commissioning & Maintenance

Deferred until the equipment list and usage needs are finalized.

• Is there a defined commissioning protocol for the control system? What constitutes “working” for each preset? Who signs off on acceptance? (e.g., “recall Wedding preset, verify lighting dims to target level within 5 seconds, verify audio preset is active, verify projector is on and screen is down.”)
• Can the AMX programmer access the system remotely for diagnostics and updates? Is there VPN or remote access to the AMX processor, BLU-100s, or M4250? If so, is this documented and secured?
• Who is responsible for firmware updates on each networked device (BLU-100, SVSi, M4250, RLNK, VX4S, ClickShare, LP10, Mac mini)? Is there a maintenance window policy?
• Is there a manual workaround for routing the auditorium overflow feed without AMX involvement (e.g., manually subscribing the SVSi decoder to ross-01 via the SVSi web interface), given that the infrastructure is being installed now but overflow programming is deferred?

South Gym Networking Plan

Requirements

• Local network switch for AV control devices
• Network connectivity back to the facility’s core switch for AMX control and audio/video feed routing
• VLAN structure compatible with the existing facility network

Uplink

The South Gym connects to the facility network via a fiber run from the IT room. This provides the uplink for AMX control, SVSi video routing, and VLAN trunking.

Topology: Core Switch (Netgear GSM4248PX) > IT Room Switch (Netgear GSM4230PX) > South Gym Switch (Netgear GSM4248PX). The IT room switch has free SFP ports for the fiber uplink. The trunk carries tagged traffic only (no native VLAN).

LC duplex termination throughout.

The fiber path has three segments:

Segments 1–2 use armored fiber for all exposed runs. Segment 3 uses non-armored fiber – a deliberate choice because armored cable is difficult to position and terminate in a rack. Both cable types are Corning OS2/SMF-28 singlemode and are splice-compatible, though the cable is pre-terminated on spools so no field splicing is needed.

SFP+ transceivers: 10G SFP+ trunks, matching the rest of the building. Third-party/generic SFP+ modules are used, same as existing facility trunks. Specific model TBD during commissioning.

Strand allocation

Junction box (12 strands in, 6 continue):

• 6 strands continue to the AV rack (segment 2)
• 6 strands spare for future use
• Junction box is accessible by removing a drop ceiling tile

AV rack (6 strands):

• 2 strands: AV switch (Netgear M4250)
• 2 strands: IT switch
• 2 strands spare for future use

Fiber is pre-labeled at the factory. As-built documentation showing strand-to-termination mapping will be created after installation.

Post-install fiber validation

No OTDR is available, and none is needed for pre-terminated cable on a short run. Post-install validation steps: (1) confirm 10G link negotiation on both ends, (2) read SFP+ DDM/DOM optical RX power from the M4250 management interface and record as baseline, (3) run iperf3 to verify sustained throughput, (4) monitor switch error counters (CRC, frame errors) over the first few days. Cable attenuation ratings will come from the manufacturer.

Fiber uplink failure analysis

The fiber uplink is a single point of failure for AMX control, SVSi video routing, LP10 network streaming, ClickShare discovery, and rack PC internet access. Per-device behavior if the uplink is lost:

Fallback: A Raspberry Pi running Bitfocus Companion in the South Gym rack provides local control; access via a laptop plugged into the local M4250. Analog audio paths continue working independently of the uplink. See control.md Failure & Fallback section for full details.

Switch

Netgear M4250 PoE+ GSM4248PX (48-port) as the local managed switch. The M4250 supports the facility’s VLAN scheme and has SFP+ slots for the fiber uplink to the IT room.

Why M4250 PoE+ (not PoE++)? PoE+ (802.3at, 30W/port) provides sufficient power for AMX touch panels and SVSi endpoints. PoE++ (802.3bt, 60-90W/port) would add cost for capacity we don’t need – none of the planned PoE devices require more than 30W. Why Netgear M4250? The M4250 is the facility standard – it’s already deployed in the auditorium, atrium, and for digital signage. Using it in the South Gym maintains consistency across the facility for management, sparing, and troubleshooting. It’s a managed switch designed for AV applications, with IGMP snooping, QoS, and VLAN support out of the box.

Engage Controller: All facility M4250s are managed via Netgear Engage Controller, which pushes consistent VLAN, QoS, IGMP snooping, and unregistered multicast filtering settings across every switch automatically. The South Gym M4250 will receive the same configuration as the rest of the facility.

Monitoring: Addressed in control.md – Prometheus via SNMP for switch stats, Uptime Kuma for device pings. Same facility monitoring stack as all other switches.

Firmware updates: SVSi endpoints and RLNKs are updated during commissioning; hardware is mostly discontinued so future updates are unlikely. M4250s are updated periodically via Engage Controller. BLU-100s have not been updated and will only be updated if a compelling reason arises. No formal maintenance window policy.

Security configuration: Same as the rest of the facility M4250s – SSH enabled, admin user with SHA512-encrypted password, SNMP with SHA512 auth and read-only community string restricted by source IP, HTTP/HTTPS on non-default ports (49151/49152). Engage Controller pushes consistent config. See existing switch configs in this repo under Networking/. Unused switch ports (e.g., long-term VX4S ports on VLAN 21) are not administratively shut down – physical access to the rack closet is restricted, so unused port shutdown is not necessary.

IGMP and multicast: The M4250 does not act as an IGMP querier on VLAN 25 – it delegates to the core switch, using the existing facility IGMP settings. Multicast containment (pruning) is managed at the core switch. This is the same architecture used across the rest of the building. With properly configured IGMP snooping, unsubscribed SVSi streams are pruned and do not consume switch bandwidth.

SVSi compatibility: SVSi stream delivery over M4250 switches has been tested and works fine across the rest of the building. The N4321 audio transceiver uses the same IGMP multicast mechanism as SVSi video – it is not AES67 and has no PTP requirements.

Switch port count

~19 copper ports + 1 SFP+ uplink at full build-out. Near-term (before LED wall): ~14 ports. A GSM4248PX (48-port) provides comfortable headroom for future expansion.

Not on M4250: Midas DL16 (rack and portable) are AES50 only – no Ethernet. IT switch has its own fiber uplink. School AP is on a separate network.

Wireless device notes:

• Arylic LP10: WiFi disabled; wired-only on VLAN 5 (SPACnet) to prevent bridging two networks or creating a rogue AP.

• Barco ClickShare: Uses facility WiFi, not its own AP. WiFi band/channel coordination is IT’s responsibility.

• Midas M32R: Ethernet is used for the remote control app. On VLAN 21 (Control), accessible via IT WiFi which broadcasts into the gym space.

• VLAN assignment for Rack PC and ClickShare – both may need to be on SPACnet (VLAN 5) for user device discovery, or split across VLANs with appropriate routing

• Final AMX touch panel count

PoE consumers

This list will be updated as equipment is added. The M4250 PoE+ models provide up to 30W per port (IEEE 802.3at). Total switch PoE budget depends on the model selected.

VLANs

The facility uses a standard VLAN scheme across all AV switches. The M4250 in the South Gym will trunk these VLANs over the fiber uplink. Not all facility VLANs are needed in the gymnasium.

South Gym active VLANs: 1, 5, 21, 25. The trunk port to the core switch should carry at least these four. Other VLANs can be pruned at the trunk or simply left unconfigured on local ports.

Inter-VLAN routing is handled on the IT room switch (not on the M4250). VLAN 21 (Control) can access VLANs 5 (SPACnet) and 25 (SVSi). No ACLs or firewall rules are in place. Trunk latency has not been observed as an issue. This means the remote AMX processor (NX-4200) reaches all South Gym devices on VLAN 21 through the trunk – including the RLNK-915R for power sequencing and the AMX EXB-COM2 for RS-232 control of the ETC Paradigm ACP (both lighting layers). If the fiber uplink is down, the Raspberry Pi running Bitfocus Companion in the South Gym rack provides local control as a fallback.

BSS BLU-100 control protocol: HiQnet uses IANA port 3804 (TCP for reliable control, UDP for discovery datagrams). Discovery uses IP broadcast, not multicast – DiscoInfo messages are network-broadcast, so IGMP snooping on VLAN 21 does not need any special configuration for HiQnet. This is distinct from VLAN 25 (SVSi), which does use IGMP multicast. See HiQnet Third Party Programmer’s Guide sections 4.5.1–4.5.2 and 4.1.6.

AMX RS-232 bridge: The remote AMX NX-4200 processor sends RS-232 commands to the ETC Paradigm ACP (PSAP protocol, controls both gymnasium and event lighting layers) via an AMX EXB-COM2 ICSLan serial expansion module (FG2100-22) in the South Gym rack, on VLAN 21 (Control).

IT Network

The IT team runs on separate hardware from the AV network. Our responsibilities:

• Pull the fiber and all cabling (we handle all fiber-related work)
• Install their switch in our rack (we provide the rack space and physical install)
• Pull cable for their wireless access point (Cat 6A, matching all other new data runs)

IT’s responsibilities:

• Configure their switch
• Install and configure their AP on the junction box we provide

School Network

The school has an existing AP in the room with an existing cable drop. We need to provide:

• Conduit run to the new AP mounting location
• Junction box for AP mounting
• Attempt to preserve the existing cable and extend it to the new box (depends on available slack) – the rest of the building uses Cat 5e, so the existing school AP cable is likely 5e (adequate for PoE at these distances)
• TBD: Coordinate with the school division on AP cabling requirements

AV Rack

See Rack Plan for rack layout, power budget, and location details.

Patch panels

4U allocation in the rack (cross-reference: rack.md U1–4):

• U1: Fiber patch panel (1U)
• U2–3: Neat patch (2U) – clean cable management between patch panels and switches
• U4: Copper patch panel (1U, 24-port Cat 6A)

Specific panel models TBD.

Network Drops

Cat 6A drops required within the South Gym. This list will be updated as equipment is added or removed.

In-rack devices share a short patch to the M4250 and don’t need dedicated cable runs.

• TBD: Wall plate locations and quantities
• TBD: Additional drops as equipment list is finalized

Considerations

• Run sufficient Category 6A cabling within the South Gym – even if not all ports are used initially, pulling cable during renovation is far cheaper than retrofitting later
• LED wall data cabling (long-term): Cat 6A – overkill for the VX4S panel protocol but matches everything else in the build and is guaranteed to work. Cable count TBD once LED wall configuration is finalized.

Commissioning Documentation

The following tables will be completed during commissioning and serve as the as-built network documentation.

IP Address Assignments

Switch Port Map

• Patch panel port assignments to be completed during commissioning
• Actual switch port numbers may change — this is a logical mapping

Patch Cable Labeling

• TBD: Labeling standard (Brady, P-touch, heat-shrink) and naming convention. (Cross-reference: rack.md cable labeling question.)

Configuration Backup

• Export M4250 startup-config after commissioning and store in this repo under Networking/South Gym Switch/

Open Questions

VLAN Design & Switch Configuration

• What STP mode is in use facility-wide (STP, RSTP, MSTP)? Should edge ports (SVSi endpoints, BLU-100, touch panels) be configured as edge/portfast to avoid 30-second STP delays on link-up? Is BPDU guard or root guard needed on any ports? Using M4250 defaults. Worth future consideration but hasn’t historically been a problem.

Device Discovery Protocols

• Multiple devices rely on mDNS/Bonjour and SSDP for user device discovery. These protocols do not cross VLAN boundaries without a helper/proxy (e.g., Avahi reflector, mDNS gateway). The existing facility switches have no bonjour enable. How will the LP10 (VLAN 5, AirPlay 2/Google Cast/Spotify Connect) and ClickShare (VLAN TBD, AirPlay/Miracast) become discoverable to user devices on IT WiFi (likely a different VLAN)? A dedicated “South Gym AV” WiFi network on the same VLAN as these devices would provide native mDNS/Bonjour/SSDP discovery without cross-VLAN helpers. Details TBD — VLAN assignment, AP hardware, SSID/security, and whether this is an additional AP or a repurpose of an existing one.
• If the ClickShare is on a different VLAN than user devices, will native AirPlay/Miracast (which relies on mDNS/Bonjour) fail? The video plan explicitly lists ClickShare as the wireless presentation path for teachers, presenters, and wedding families – this is a core use case. Addressed by the “South Gym AV” WiFi network — if ClickShare and user devices are on the same VLAN, AirPlay/Miracast discovery works natively.

Physical Layer & Cabling

• What are the Cat 6A run distances from the rack to: the back-wall N1115-WP wall-plate encoder, the ceiling-mounted NMX-DEC-N1222A decoder, the M32R floor drop(s), and AMX touch panel location(s)? Are all runs within the 100-meter Cat 6A maximum? PoE performance degrades over distance. (Cross-reference: electrical.md conduit path questions.) All runs expected to be well under 100m, but exact distances need to be measured on-site.

SVSi / AV-over-IP

• What is the typical bandwidth of an MPC-compressed 1080p60 stream (typically 200-400 Mbps)? How many simultaneous SVSi streams could be active at once (2 encoders local + 1 overflow from auditorium, 2 decoders subscribing)? Does the 1 Gbps fiber uplink have sufficient headroom for worst-case multicast load plus control traffic plus rack PC internet traffic? Bandwidth is likely higher than the 200-400 Mbps estimate — need to verify from encoder specs. The fiber uplink is 10G SFP+, so headroom should be substantial.

Wireless & IoT

• The LP10 has Bluetooth 5.2 with a 15m range rating. In a gymnasium with metal ceiling structure, what is the realistic Bluetooth range from the rack closet to a user in the gym? Is the rack closet door solid or does it attenuate Bluetooth? If range is insufficient, the Bluetooth fallback does not actually work. Range may be poor through the closet door/walls — needs real-world testing after install. WiFi-based playback (AirPlay 2, Google Cast, Spotify Connect) is likely the more reliable path. Bluetooth is a nice-to-have, not a guaranteed fallback.

M32R Floor Drop

• Is the M32R floor drop a single Cat 6A jack, or does it need multiple jacks (one for Ethernet, one for AES50 if carried over structured cabling)? AES50 uses a proprietary protocol that is not standard Ethernet – if AES50 is expected to traverse a patch panel and switch, it will not work because AES50 is not routable.
• Does the floor drop location need to support the M32R cart on either side of the room, or is a single fixed drop sufficient? If two locations, are two floor drops needed? (audio.md raises this question.)
• Is the floor drop a flush floor box, and does it need to be rated for gymnasium floor traffic (rolling carts, ball impacts)?

LED Wall Data Cabling (Long-Term)

• Should cables be pulled into the LED wall conduit now (risk of damage during construction), or should conduit be left empty for future pull? What is the maximum distance from the rack to each candidate LED wall location (standard 100m limit applies)? Deferred — to be determined with the LED wall manufacturer.

Network Monitoring & Operations

• The M4250 PoE model selection (24 vs. 48 port) depends on the total PoE budget. Known PoE consumers total ~33W (decoder + encoder), plus TBD touch panel(s) at 12-25W each. Has the selected model’s PoE budget been verified as sufficient with headroom for future PoE devices? Equipment list is nearly finalized. PoE budget is overkill — the GSM4248PX provides 960W against an estimated total PoE draw well under 100W. Verify once final device list is locked.

South Gym Lighting Plan

Current State

• Fixtures: Old fluorescent tube fixtures throughout the space. Aging ballasts, no dimming capability, fixed color temperature. Tubes are becoming harder to source.
• Dimming: Two ETC SmartPack 12x1200W wall-mount dimmer packs are available (24 channels total, 1200W per channel). One is currently installed in the South Gym; the second is available but not yet installed.

Requirements

• General illumination sufficient for sports and active use (gymnasium layer)
• Dimmable lighting for worship, presentations, and events (event layer)
• Physical wall switches for daily gymnasium operation – simple, familiar, no dependency on AMX or network
• Zoned control – ability to light different areas independently (e.g., stage area vs. full gym)
• Reliability – low maintenance, long lifespan
• Energy efficiency – reduced operating costs vs. current fluorescent fixtures

Architecture

The lighting system is split into two independent layers, each optimized for its use case:

Both layers are controlled by a single ETC Paradigm ACP. The Paradigm outputs sACN to an ETC Response 0-10V Gateway for gymnasium fixtures, and DMX512 directly to SmartPacks for event lighting. Both layers are managed through a single RS-232 link from AMX using the Paradigm Station Access Protocol (PSAP). Despite sharing a controller, the two layers remain operationally independent – different fixtures, different dimming technologies, different physical outputs. The gymnasium layer can also operate fully independently via physical button stations.

Control Authority – Gymnasium Layer

The Paradigm button stations are the primary authority for the gymnasium layer. AMX is a secondary input:

• Button station ON – fixtures are on. AMX cannot override this.
• Button station OFF – AMX can control the gymnasium fixtures via Paradigm serial commands (turn on, adjust dimming).

This gives school staff simple physical control for daily use, while AMX retains the ability to incorporate the gymnasium fixtures into coordinated event presets when the button stations are not in use.

The Paradigm ACP manages the arbitration between button station inputs and serial commands using its built-in priority system. Button station inputs are assigned higher priority than the serial input.

Control Authority – Event Layer

The event layer is AMX-only. There are no physical switches. AMX sends RS-232 commands to the Paradigm ACP via PSAP, which outputs DMX512 to the SmartPacks. The Paradigm’s local presets provide a fallback if AMX is unavailable – presets can be recalled from button stations (if event presets are assigned to a station) or from the Paradigm’s front panel in the rack closet.

Gymnasium Layer – ETC Paradigm ACP

Why Paradigm?

The facility already uses ETC Paradigm architectural controllers for house lighting elsewhere in the building (see Lighting/2018 Handover for the existing installation). The Paradigm ACP provides:

• 0-10V dimming – the Paradigm outputs sACN over Ethernet to an ETC Response 0-10V Gateway (RSN-LV-R3), which provides 24 channels of 0-10V sink control for gymnasium fixtures
• Button station inputs – ETC Unison Heritage button stations (or similar) provide simple physical wall switches
• RS-232 serial port – a single RS-232 link from AMX (via EXB-COM2 port 1, PSAP protocol) controls all lighting – both gymnasium and event layers
• Built-in preset storage – the Paradigm stores its own presets, so button stations work independently of AMX
• Institutional familiarity – staff and volunteers already know the Paradigm button stations from the rest of the facility

Fixtures

Design Targets

• Target illuminance: 70 fc average on the floor (exceeds IES RP-6 recreational minimum of 30-50fc; provides headroom and allows dimming down for cleanup/setup use)
• Dimming rationale: 0-10V dimming is primarily for reducing output during cleanup, setup, and casual use where full sports-level illumination is unnecessary. This does not substantially affect fixture cost since most high-output LED gymnasium fixtures include 0-10V drivers as standard.
• Mounting height: ~20’ trim (open exposed ceiling, no drop ceiling)
• Lumen maintenance: Design should apply a light loss factor (LLF) of ~0.85-0.90 so that maintained lumens still meet the 70fc target at end of useful life. This means the initial design targets ~78-82fc.
• Adaptability: The 0-10V dimming also provides insurance – if 70fc proves to be more than needed after installation (or after future surface changes increase reflectance), the system can be dialed back without replacing fixtures.

Specifications (TBD)

• High-output LED suitable for sports illumination
• 0-10V dimmable (compatible with Paradigm ACP output)
• Impact-rated for gymnasium environments (IK08 minimum, IK10 preferred – balls will hit fixtures)
• Controlled glare / low UGR for overhead sports (volleyball, basketball involve looking upward)
• CRI 80+ minimum (CRI 90+ if games may be video recorded/streamed)
• CCT TBD – sports/gymnasium use typically 4000K-5000K (single fixed CCT likely sufficient since atmospheric lighting is handled by the event layer)
• Efficacy 140+ lm/W preferred (energy code compliance and reduced operating costs)
• Mounting: pendant-hung or chain-mounted from exposed structure at ~20’

Preliminary Photometric Estimate (Zonal Cavity Method)

A rough zonal cavity calculation provides planning-level fixture counts and power estimates. These numbers are useful for electrical circuit sizing and budgeting before a fixture is selected. A proper photometric layout using DIALux evo (free) with real fixture IES files is still needed for the final design – the zonal cavity method cannot verify uniformity, glare, or point-by-point illuminance. DIALux can import DWG floor plans directly and produce point-by-point illuminance grids, uniformity ratios, and UGR glare ratings.

Assumed room dimensions: ~100’ x 60’ (~6,000 ft²). Actual dimensions TBD – these are planning estimates only.

Inputs:

Room Cavity Ratio (RCR): 5 x 20 x (100 + 60) / (100 x 60) = 2.67 (moderate)

Estimated Coefficient of Utilization (CU): ~0.58 for a typical wide-distribution LED high bay at this RCR with these dark surfaces. This is the weakest assumption – actual CU depends on the specific fixture’s photometric distribution and could range from 0.50 to 0.65, swinging the fixture count by ~20%.

Fixture count estimates:

N = (70 fc x 6,000 ft²) / (Lumens per fixture x 0.58 x 0.87)

Total wattage converges around ~6,000W (~1.0 W/ft²) regardless of fixture size, which should be well within energy code limits.

Spacing check: For 28 fixtures (30,000 lm) in a 7x4 grid: ~14.3’ x 15’ spacing, S/MH ratio ~0.75. This is within the typical S/MH max of 1.0-1.5 for wide-distribution high bays, so uniformity should be achievable.

Future state impact: When walls are renovated from brick (~25%) to painted drywall (~65%), the CU increases to approximately 0.65-0.70. The same fixtures would then produce roughly 80-85fc – the 0-10V dimming accommodates this without changing hardware.

Photometric Calculation – Remaining Prerequisites

The preliminary estimate above is sufficient for planning. A final photometric layout requires:

• Confirmed floor dimensions (length x width)
• Uniformity requirement – IES RP-6 recommends min:avg ratio of 0.7 or better for recreational sports (minimum 49fc if average is 70fc). Confirm this is acceptable or if a tighter ratio is needed.
• Glare requirement – is there a specific UGR target, or “as low as reasonably achievable”? The sports played in the gym (basketball, volleyball, badminton) determine how critical upward glare control is.
• Fixture IES photometric files – once candidate fixtures are identified, their published photometric data (.ies files) drive the layout calculation, including spacing-to-mounting-height ratio (S/MH).
• Projection screen location – gymnasium fixtures at full brightness may wash out the screen surface. The photometric layout should account for fixture placement and shielding near the screen.
• Structural mounting points – the exposed ceiling structure determines where fixtures can physically be hung. This may constrain the ideal photometric layout.
• Alberta energy code (NECB or equivalent) maximum lighting power density (W/ft²) for gymnasiums – confirm the fixture selection and layout comply.

Surface Reflectances

The photometric calculation should use the current state for design purposes – this is the worst case (darkest surfaces, least reflected light). The future state will increase reflectance, which raises effective illuminance. The 0-10V dimming can then be used to dial back output if needed.

Note: The wall change from brick (~25%) to painted drywall (~65%) is significant – it roughly doubles wall reflectance, which will noticeably increase overall light levels in the space. This reinforces the value of 0-10V dimming for post-renovation adjustment.

Zoning

Button station presets could include:

• “Full Bright” – all gymnasium zones at 100%
• “Half Gym A / B” – one half on, the other off (if the zone split is needed)
• “Off” – all gymnasium zones off

Wiring

• 0-10V signal pairs from the Response 0-10V Gateway to each fixture or group of fixtures. Low-voltage, small gauge. The gateway can be mounted near the fixtures (closer to the loads) to keep 0-10V runs short.
• Cat 5e/6 from the Paradigm ACP to the Response Gateway (sACN over Ethernet). This can share the existing AV network (VLAN 22) or use a direct connection.
• Line power to the gymnasium fixtures from the electrical panel (separate from SmartPack circuits). The 0-10V signal controls dimming, not line power.
• Button station wiring from wall-mounted stations to the Paradigm. Low-voltage (ETC button stations use a proprietary low-voltage bus).

Event Layer – ETC SmartPacks (via Paradigm ACP DMX Output)

Available Equipment

24 channels of dimming at 1200W per channel. The SmartPacks are existing equipment being reused – they provide ample dimming capacity for the space and are already proven in the facility. Each SmartPack requires a 60A two-pole breaker and is hardwired with a single feeder (6/4 SO or SJO cable). See Electrical Plan for circuit details.

Both SmartPacks will be wall-mounted together in the rack closet. This keeps DMX cable runs short (from the Paradigm ACP’s DMX output) and centralizes all power distribution equipment. Relocating the kitchen SmartPack constitutes a new installation under the Safety Codes Act and requires a fresh inspection. A pre-installation condition assessment is not needed – SmartPacks are built for heavy theatrical use, and any channel issues will surface during commissioning.

Why SmartPacks + Paradigm ACP? The SmartPacks accept DMX512, and the Paradigm ACP has built-in DMX512A output ports. AMX sends RS-232 commands to the Paradigm via PSAP (the same serial link that controls the gymnasium layer), and the Paradigm outputs DMX512 to the SmartPacks. This eliminates the need for a separate RS-232-to-DMX bridge – one controller handles both layers. Presets are stored locally in the Paradigm’s non-volatile memory and can be recalled from button stations or the Paradigm’s front panel if AMX is unavailable. See equipment reference.

Alternative: DFD 2322DMX. A DFD 2322DMX RS-232-to-DMX bridge is available as a documented alternative if the Paradigm’s DMX output proves unsuitable for the SmartPacks (e.g., timing issues, channel count limitations). The 2322DMX would restore the original two-serial-link architecture. See equipment reference.

SmartPack Compatibility

ETC SmartPacks are forward-phase (leading-edge) dimmers. This affects fixture selection:

• Incandescent/halogen: Fully compatible, dims smoothly
• LED fixtures: Must use LED fixtures with drivers rated for forward-phase dimming. Not all LED drivers are compatible – incompatible drivers can cause flickering, buzzing, or limited dimming range. ETC publishes compatibility lists for their dimmers.
• Non-dim loads: SmartPacks can be configured per-channel for non-dim (switched) mode if some circuits don’t need dimming

Fixture selection should prioritize SmartPack-compatible LED fixtures to get both the energy savings of LED and the dimming flexibility the SmartPacks provide. (See equipment reference for SmartPack specs.)

Alternative Considered: ETC ArcSystem Pro (Rejected)

ETC ArcSystem Pro fixtures (DMX-controlled architectural LEDs with built-in drivers) were evaluated as an alternative to conventional fixtures on SmartPacks. ArcSystem would eliminate the SmartPacks entirely — fixtures take DMX directly from the Paradigm ACP and handle their own dimming, with smooth dimming to true zero, CRI 90+, and 50,000-hour LED life.

Why it was rejected: cost. For a 100x60’ gymnasium event layer (~20-28 fixtures for stage wash, general fill, and perimeter zones), ArcSystem Pro four-cell fixtures at ~$1,100-1,300 USD each put the fixture-only cost at $24,000-35,000. Conventional LED or incandescent fixtures on the existing SmartPacks would be $1,000-5,000 for comparable coverage. The SmartPacks are already owned and provide 24 channels of forward-phase dimming at no additional cost.

ArcSystem does simplify wiring (DMX daisy-chain vs. dedicated power home runs per SmartPack circuit) and avoids forward-phase dimming compatibility concerns, but neither issue justifies a 10x+ fixture cost premium in a multi-purpose gymnasium. ArcSystem is better suited to dedicated performance venues where dimming quality is the primary requirement.

Fixture Protection

The gymnasium ceiling is exposed (open structure) – there is no slatted ceiling to shield event fixtures from ball impacts. Any theatrical or architectural fixture mounted in the open ceiling needs physical protection.

Options:

The SSRC Spotlight Cage is the better fit for individual fixtures scattered across zones. The Gym Light Cage is better if fixtures are clustered in rows along a pipe or truss. Both are available in black, white, silver, or custom colors.

Fixture protection cost should be factored into the per-fixture budget when selecting event layer fixtures.

Fixtures

TBD. Event fixtures should be:

• Forward-phase (leading-edge) dimmable – compatible with ETC SmartPacks
• Good dimming curve (smooth, low minimum without flicker)
• High CRI for formal events and food service
• Appropriate fixture types per zone (general, accent, stage)

Zoning

All 24 SmartPack channels are available exclusively for the event layer. Zoning can be fine-grained.

Wiring

The event layer requires new wiring from the SmartPacks to fixture locations:

• Individual home runs from each SmartPack channel to its fixture group. SmartPack channels need individual circuits, not daisy-chains.
• Existing fluorescent wiring is not reusable for per-channel dimming. New circuits required.
• DMX cable from the Paradigm ACP’s DMX512A output to both SmartPacks, in its own low-voltage raceway separate from SmartPack power feeds.

Design Considerations

Existing Wiring

The current fluorescent fixtures are daisy-chained in approximately 8 groups. The existing wall switches are dry-contact, connected to a switching box next to the electrical panel. This wiring is not directly reusable for either layer – SmartPack channels need individual home runs, and the gymnasium fixtures will likely need new circuits as well (different fixture locations, 0-10V signal pairs, different switching). The existing conduit paths from the old switching box cannot be reused as pull paths either – the old switching box and the new rack closet are on opposite sides of the facility, so new conduit runs are required.

The existing ~8 groups may inform the gymnasium zoning layout – if the fixture positions and groupings are reasonable, new circuits can follow similar zones.

Emergency / Exit Lighting

Emergency and exit lighting is on a completely separate system, independent of both the SmartPack circuits and the gymnasium layer. No AMX preset or SmartPack fault can disable it.

EXB-COM2 Port Allocation

The AMX EXB-COM2 in the South Gym rack has one serial port allocated for lighting:

A single RS-232 link to the Paradigm ACP controls both lighting layers. Port 2 is available for future expansion.

AMX Scene Presets

AMX presets coordinate both layers simultaneously. Each preset specifies the state of both the gymnasium layer and the event layer, all managed through the Paradigm ACP via PSAP commands:

Note: If the gymnasium layer button stations are active (wall switches on), AMX cannot override them to off. The “Wedding” preset would leave the gymnasium layer in whatever state the button stations dictate. In practice, whoever sets up for an event would turn off the gymnasium wall switches before recalling an event preset.

Open Questions

Electrical & Code

• What is the distance from the rack closet to the farthest fixture location? Long runs affect voltage drop and conductor sizing (applies to both layers).
• How many conductors will share each conduit from the closet to fixtures? Conduit fill derating (CEC Table 5C) could require upsizing wire.
• Forward-phase dimmers produce harmonic content on neutral conductors – do shared neutrals need to be upsized per CEC Rule 4-024? (Event layer only – gymnasium layer uses 0-10V dimming which does not produce harmonics.)
• Does minimum illumination for paths of egress need to be enforced as a floor in AMX programming and/or Paradigm programming (e.g., “Wedding” dimmed zone can’t go below code-required levels)?
• Has the available fault current at the new panel been determined, and do the SmartPacks’ internal overcurrent devices have adequate interrupting ratings?
• Does the full scope of work (SmartPack relocation, new panel, home runs, gymnasium fixtures, Paradigm, button stations) need a single electrical permit, and has the AHJ been consulted?
• Are there any code requirements for emergency or exit lighting (Alberta Building Code / NBC)?
• What electrical circuit feeds the gymnasium fixtures? This is separate from the SmartPack circuits. Sizing depends on fixture count and wattage.
• What is the Paradigm ACP’s power requirement and how is it fed? Depends on enclosure choice (ERn has its own AC input; DIN rail P-ACP-D uses an external 24V PSU).
• What is the Response 0-10V Gateway’s power requirement? Requires 18-24 VDC via external PSU (ETC PS-DIN24). Where is the gateway mounted, and how is the PSU powered?

Gymnasium Layer – Fixture Selection & Photometric Design

• What are the floor dimensions (length x width)? Required for photometric calculation.
• What uniformity ratio is required? IES RP-6 recommends min:avg of 0.7 for recreational sports (min 49fc at 70fc avg). Is this acceptable, or is a tighter ratio needed?
• What specific UGR (Unified Glare Rating) target is required, given basketball and volleyball involve looking upward? Or is “as low as reasonably achievable” sufficient?
• What impact rating (IK rating) is needed for fixture lenses? IK08 minimum, IK10 preferred for gymnasium use. Confirm based on sports played.
• What CCT (color temperature) for gymnasium fixtures? 4000K-5000K is typical for sports. Single fixed CCT likely sufficient since atmospheric lighting is the event layer’s job.
• What minimum CRI is required? CRI 80+ for sports; CRI 90+ if games may be video recorded or streamed.
• What is the maximum acceptable ambient light level on the projection screen surface? Gymnasium fixtures at full brightness may wash out the screen – fixture placement and shielding near the screen matters.
• Where are the structural mounting points in the exposed ceiling? This constrains where fixtures can physically be hung and may limit the photometric layout.
• Does the Alberta energy code (NECB or equivalent) set a maximum lighting power density (W/ft²) for gymnasiums? Confirm compliance with fixture selection.
• How many existing fluorescent fixtures are there, and what type?
• How many gymnasium zones/circuits are needed?
• Do any use cases need a “Half Gym” zone split (e.g., two classes sharing the gym)?

Event Layer – Fixture Selection

• What is the minimum dim level required for events like weddings – is 10% sufficient, or does the aesthetic need fixtures that dim below 5%?
• Do SmartPacks have a minimum load threshold per channel below which forward-phase dimming doesn’t work correctly with LED drivers?
• Is tunable white (variable CCT) needed to shift warmer for ceremonies and cooler for sports, or is a single fixed color temperature acceptable?
• What minimum CRI is required, considering formal events and food service (dinner events)?
• Are perimeter/wall accent fixtures a different type (strip, wall-wash, sconce) than the general field fixtures, and have those been separately checked for forward-phase compatibility?
• Does the stage/front zone need a different fixture type than the general field (e.g., lower-mount theatrical fixture)?
• How many event zones/circuits are needed (up to 24 available)?

Physical Installation

• What is the usable wall area in the rack closet for two SmartPacks, and is there space for both while maintaining code-required working clearances in front of all electrical equipment?
• How do SmartPack output wires exit the units (top/bottom/side), and is there clearance for conduit sweeps given the rack and other equipment?
• What is the thermal load from both SmartPacks, and has it been added to the rack closet ventilation sizing?
• What is the demolition plan for existing fluorescents – has an asbestos survey been done on fixture bodies, ballasts, or ceiling materials?
• Do existing ballasts contain PCBs (pre-1979) requiring hazardous waste handling?
• What happens to the existing dry-contact switching box once decommissioned?
• Is the renovation happening in a fully vacated gym, or are there schedule constraints (school calendar, events) that limit the work window?
• What lift equipment can physically enter the gym, and are doors wide enough?
• Can the existing ~8 daisy-chain groups be mapped to inform the new zoning layout?
• Where will the Paradigm ACP be mounted (rack closet, near the electrical panel, elsewhere)? The enclosure type is TBD – either an ERn wall-mount control enclosure (Mk1 or Mk2) or a DIN rail enclosure with a P-ACP-D (Mk2 only).
• Where will the Response 0-10V Gateway be mounted? It can be near the ACP (rack closet) or near the gymnasium fixtures to keep 0-10V cable runs short. DIN rail mount, requires only Ethernet and 24V DC power.
• Where will the Paradigm button stations be mounted? Near the main entrance? Multiple locations?

Control Integration

• What fade times are required per preset (e.g., slow crossfade into “Wedding,” snap to “Cleanup”)?
• When AMX fires a room preset, what is the defined sequence between lighting (both layers), audio, and video commands?
• For the M32R override scenario, is there a corresponding lighting state change?
• Is there a requirement for auto-off after inactivity (occupancy sensing)? The Paradigm supports occupancy sensor inputs if needed.
• Is time-based scheduling needed (e.g., “School Gym” at 7 AM, “Off” at 10 PM)? The Paradigm supports time-based scheduling natively.
• The Paradigm does not have a built-in heartbeat like the 2322DMX’s H 1. AMX must use poll-based watchdog (periodic PSAP status queries) to detect a dead serial link. What polling interval is appropriate?
• How many Paradigm presets are needed to cover both gymnasium and event layer scenes? The Paradigm supports a large preset count – confirm capacity for the combined scene list.
• Should a button station near the gymnasium entrance include event layer preset buttons (e.g., a “Wedding” button) for non-technical fallback?
• What is the DMX channel assignment plan for the SmartPacks (which Paradigm DMX channels map to which SmartPack channels/fixture zones)?
• Who is responsible for configuring the Paradigm ACP in ETC LightDesigner (presets, zones, button station assignments, DMX channel map)?

Cross-Reference Updates Needed

The Paradigm-as-both-layers architecture affects several other plan documents:

• control.md – AMX Responsibilities table: Paradigm ACP controls both layers via PSAP. Update serial protocol details, monitoring, and failure/fallback.
• equipment-reference.md – add ETC Paradigm ACP entry with specs, PSAP protocol, and button station details. Update 2322DMX entry as alternative/spare.
• electrical.md – update DMX control path (Paradigm ACP replaces 2322DMX as DMX source), RLNK outlet 4 now spare, grounding references.
• rack.md – position 24 now available (Paradigm ACP mounts in ERn or DIN enclosure, not in rack). RLNK outlet 4 now spare.
• networking.md – update EXB-COM2 references (serial bridge to Paradigm ACP, not 2322DMX), failure table, IP assignment notes.

South Gym AV Rack

Location

The AV rack will be in a closet at the front of the room. Room drawings are pending.

Closet details

• Closet door is hinged, swings outward. Does not block rack or SmartPack access.
• Door is wide enough to carry in a fully assembled 42U rack – no need to build in place.
• Minimum 36“ clear working space in front of the rack and SmartPacks per electrical code is confirmed.
• Closet has lighting for maintenance work.

Installation sequence

All installation is surface-mount – no in-wall rough-in or wall finish dependency. Conduit, boxes, and rack can be installed in any practical order. Only constraint: the fiber wall box should be in place before the rack is positioned in front of it.

The rack is already owned and will be reused from its current location, just relocated to the South Gym closet. No lead time or ordering freeze concern.

Rack Layout

Middle Atlantic ERK-4025 enclosed rack — 40U, 25“ OD depth (23-1/2“ usable between rails), 22“ OD width (19“ panel). No front or rear doors. No slide rails. See equipment reference. Layout from top to bottom. This will be updated as equipment is added or removed.

Sizes marked with * are estimated and will be confirmed as models are selected. Blank positions will shift as sizes are finalized.

• TBD: Finalize layout order (heat management, cable routing)
• What specific shelf model is planned for the Mac mini at U14? Middle Atlantic makes Mac mini-specific mounts – has one been selected?
• Is the shared 1U shelf at U15 (ClickShare + LP10) a vented shelf? Both devices generate heat and need airflow.
• Has the physical fit been verified for the ClickShare base unit and LP10 side by side on a single 1U shelf?
• Are horizontal cable managers (1U) planned at any positions in the layout? None are currently allocated.
• Are vertical cable managers planned for the sides of the rack?
• Is a rack elevation drawing (to scale) planned as an installation deliverable?
• Is there a cable labeling standard for the project (Brady, P-touch, heat-shrink) and naming convention?

Depth Verification

All devices fit within the ERK-4025’s 23-1/2“ usable depth between rails. The deepest device is the Peavey Pro-LITE 5.0 at 17.25“ chassis + ~1.5“ Speakon connector + ~1.5“ cable bend = ~20.25“, leaving ~3.25“ clearance. The Midas DL16 is only 8.9“ (225 mm) deep chassis — even with 24 rear XLR connectors (~1.2“) and cable bend radius (~2.5“), total is ~12.6“. The SVSi NMX-ACC-N9206 is 5.04“ deep — trivial even with rear Ethernet cables. No extender bays are needed.

PDU Outlet Allocation

The RLNK-915R has 9 individually controllable outlets. This table tracks which device is on which outlet for AMX power sequencing.

8 of 9 outlets allocated, 1 spare (outlet 4). The M4250 and IT switch are on always-on infrastructure power from the UPS (not behind a switchable RLNK).

• Has the aggregate draw of all RLNK outlets been verified to stay within the RLNK-915R’s max continuous rating (typically 15A / 1800W at 120V)? Most device wattages are still TBD.
• Does the rack PC need a graceful shutdown signal before RLNK power is removed?

Not on RLNK:

Signal Routing & Cabling

Internal rack cabling for audio and video signal paths. All audio connections are balanced unless noted otherwise.

Audio: SVSi / N4321 decoder to BLU-100

SVSi decoder card and N4321 audio transceiver card Phoenix audio outputs (U10-11) to BLU-100 inputs (U24-25). Both sides are Phoenix (Euroblock) connectors, ~14U apart (~3-4 ft with cable management routing). Cable: Belden 8723 (2-pair, 22AWG, shielded twisted pair) – one pair per channel, stereo in a single jacket. Strip and terminate into Phoenix plugs at both ends. Balanced connection.

N4321 audio terminates at the BLU-100 (not DL16) so it’s available in both base mode and M32R passthrough mode.

Audio: BLU-100 to amplifiers

BLU-100 Phoenix outputs (U24-25) to Pro-LITE 5.0 combo XLR/1/4“ inputs (U29-36). Three amps serve different roles (ceiling speakers, subwoofers, floor monitors), so each needs its own BLU-100 output feed with role-specific DSP processing (crossover, zone routing, monitor mix). If using parallel input mode on the amps (one input drives both channels), 3 BLU-100 output channels suffice; otherwise 6. Custom cable: Belden 8451 (single pair, 22AWG, shielded twisted pair), Phoenix plug to Neutrik NC3MXX (XLR male). Balanced connection – required at this boundary (UPS ground to building ground, see Electrical Plan – Grounding). One cable per active BLU-100 output channel (3-6 total depending on parallel input mode). ~4-7 ft each with cable management routing.

All three amps share the same ground reference (dedicated building circuits), so inter-amp connections (if any) have no ground boundary concern.

Audio: LP10 to BLU-100

Arylic LP10 line output (U15) to BLU-100 input (U24-25). Custom cable: 3.5mm TRS plug (LP10 end) split to two Phoenix plugs (BLU-100 end, one per channel L/R). Belden 8723 (2-pair shielded), ~4-5 ft with routing. Unbalanced – the LP10 3.5mm output is inherently unbalanced, so this is an exception to the balanced-by-default rule. Wire signal to hot (+), ground to cold (-) and ground on each Phoenix plug. No ground boundary concern: both devices are on UPS power via the RLNK (same ground reference).

Speaker cables

Speakon speaker cables exit the bottom rear of the rack. Conduit on the closet wall carries Speakon cables from the rack to rough-in points with Speakon connections in the ceiling at speaker locations.

Video: HDMI (rack PC and ClickShare to SVSi encoder)

HDMI cables from rack PC (U14) and ClickShare (U15) to SVSi encoder cards in the cage (U10-11). Passive HDMI cables – at 3-5U the cable run is well under 1m, far below the threshold where active cables become necessary (~15m+). Passive is simpler, cheaper, and has fewer failure modes.

Power Budget

Power consumption for all rack-mounted equipment. This will be updated as specific models are selected.

Amplifier power note

The Pro-LITE 5.0 power draw varies significantly with load:

For UPS sizing and circuit planning, idle draw (90W per amp, 270W total for three amps) represents the baseline. Peak draw depends on speaker impedance and program level. Closet ventilation should account for sustained use at the expected operating load.

Electrical

Circuit requirements

Each circuit requires a dedicated breaker in the room’s new electrical panel (see Electrical Plan) and a receptacle in the rack closet. This table will be updated as equipment and UPS models are selected.

Amp breaker sizing note: The required breaker size depends on speaker impedance, which is TBD (speakers not yet selected). At 4Ω and 1/3 power, each amp draws ~15.7A (1880 VA), exceeding a 15A breaker’s continuous rating. 20A circuits provide headroom. At 8Ω, the draw drops to 10A and 15A circuits would suffice.

Amp circuit balancing: Three amp circuits across two panel legs – the electrician distributes them to balance the load (two on one leg, one on the other). See Electrical Plan.

Receptacle count

Receptacle rough-in location: All four receptacles (UPS + three amp circuits) are co-located – ceiling or low wall, depending on whether the rack closet ceiling is kept or removed. See Electrical Plan. Must be installed before the rack arrives.

Not accounted for:

• Ventilation fan (if active ventilation is selected, may need a receptacle or hardwired connection)

• SmartPacks are wall-mounted outside the rack and will need their own circuits at their mounting location (not counted here)

• TBD: Confirm amp breaker sizing once speaker impedance is known

• TBD: SmartPack circuit requirements at mounting location (2x 12 channels @ 1200W/channel = 28,800W total capacity)

Ventilation

The rack closet is adjacent to the room’s return air conduit to the air handler. The plan is to vent rack exhaust heat into the return air path. Options:

• Passive grille: Cut a vent from the closet into the return air plenum. Relies on natural convection (hot air rises). Simplest, no moving parts, no maintenance – but may not move enough air if the rack is under heavy load.
• Thermostatically-controlled exhaust fan: Mount a fan at the top of the closet venting into the return duct, triggered by a temperature sensor. More reliable airflow, only runs when needed. Adds a small amount of complexity and a failure point (fan).
• Always-on inline fan: Fan in a short duct between closet and return plenum. Simplest active option but runs continuously whether needed or not.

The amps are the primary heat concern – each can generate significant heat under sustained use. A passive grille may be sufficient for idle/light use, but an active solution is safer for sustained operation.

• TBD: Ventilation approach (passive grille vs. active fan)
• TBD: UPS sizing (based on total rack power draw, excluding amps)
• TBD: UPS model selection (1x 2U, online double-conversion)

UPS Requirements

Online (double-conversion) UPS, 2U rack-mount, positioned at U39-40. Input: 120V, NEMA L5-20R receptacle, single-pole breaker (see Electrical Plan).

Runtime target: Momentary ride-through (30s-2min) is the primary requirement. Graceful shutdown (5-10min) is nice-to-have but not a hard requirement. No need for extended runtime. This keeps battery capacity and physical size minimal.

Thermal: UPS conversion losses (typically 5-10% of load) generate heat. The UPS is listed in the power budget table with this accounted for. Actual BTU/h is TBD pending UPS model selection. Airflow interaction with the amps (positioned directly above the UPS) is flagged separately under Thermal & Ventilation open questions.

Power failure behavior: Power loss is safe for the audio signal chain. When mains power fails, the amps (on dedicated circuits, not UPS-backed) cut immediately while the DSP/mixer stay on via UPS – but amps stop amplifying and BLU-100 output has nowhere to go. Power restore is the real consideration: amps power up with a live BLU-100 signal on their inputs. The Pro-LITE 5.0 is a modern Class D design with internal soft-start and output muting during power-up, which suppresses turn-on transients. The BLU-100 output limiters provide a second layer of protection. This is a standard configuration in professional AV (amps on dedicated circuits, DSP on UPS). Verify during commissioning that the Pro-LITE 5.0 does not produce an audible thump on power-up with a live input. If it does, the BLU-100s can be programmed to power up muted and require an AMX command to unmute after a delay.

Open Questions

Thermal & Ventilation

• What is the total rack heat load in BTU/h once all TBD power figures are filled in? This determines whether the ventilation plan is adequate.
• The SmartPacks are wall-mounted in the same closet – has their heat output been added to the ventilation sizing? They’re not in the rack but contribute to closet ambient temperature.
• What is the minimum CFM required to maintain safe closet temperature at sustained heat load? This requires knowing closet volume, return air plenum static pressure, and total BTU/h.
• What is the static pressure characteristic of the return air duct? A passive grille into a pressurized plenum may have reverse airflow depending on HVAC configuration.
• Has the HVAC contractor confirmed the return duct has capacity for the additional heat load from the rack closet?
• What is the realistic sustained amp operating scenario (speaker impedance and typical power fraction)? This drives ventilation sizing – the difference between idle (~920 BTU/h total for three amps) and 1/3 power at 2Ω (~15,600 BTU/h) is enormous.
• Is the equipment layout optimized for airflow direction? The amps (primary heat source) are mid-rack with the UPS below them – if airflow is bottom-to-top, UPS heat preheats the amp inlet air.

UPS

• What is the total VA load the UPS must carry? Most rack device wattages are still TBD.
• What is the UPS battery replacement interval and who is responsible for the maintenance schedule?

Patch Panel & Switch

• What SFP+ transceivers are needed for the M4250 fiber uplink (single-mode LC, wavelength, reach)?
• The M32R connects via umbilical to a floor drop. Is AES50 carried point-to-point to the rack DL16 within the umbilical, with a separate Ethernet run to the M4250? Or is it a single cable?

Rack Closet & Installation

• What are the exact interior dimensions of the rack closet? Can a 42U rack, two wall-mounted SmartPacks, and required electrical working clearances all fit?
• On which wall(s) are the SmartPacks mounted? Is there a dimensioned layout showing rack footprint, SmartPack positions, and clearance zones?
• Who has physical key access to the closet? If the closet is locked and AMX is down, there is no lighting control.
• What are the conduit paths from the closet to: projector/decoder (ceiling), N1115-WP wall plate (back wall), LED wall stub-out, speaker locations, and lighting fixture groups?
• Does the rack include a dedicated equipment grounding bus bar? (Depends on Middle Atlantic model.)
• What is the UPS battery replacement access plan? UPS at U39-40 (bottom of rack) needs several feet of clear floor space to slide batteries out.

South Gym Electrical Plan

Overview

A new electrical panel will be installed in the South Gym to serve the AV rack, lighting dimmers, LED wall (long-term), and other room loads. This document tracks the panel’s load requirements to determine the service size needed.

SmartPack power and output distribution

Both SmartPacks are wall-mounted in the rack closet. Each is hardwired directly off the panel (not plug-and-cord) with a 60A / 240V single-phase feed using 6/4 SO or SJO cable and a 2-pole breaker. Two SmartPacks = 120A of panel capacity for dimmers. Three-phase (120/208V at 40A per unit) is an option but not required. See the ETC SmartPack FAQ for detailed input specifications. The ampacity rating of the SmartPack input terminals and maximum wire size they accept should be verified by the electrician from the unit during installation.

The SmartPack’s single feeder cable (6/4 SO or SJO) carries two hots, one shared neutral, and ground. Forward-phase dimmers produce third-harmonic current that adds on the shared neutral rather than canceling. ETC’s recommended 6/4 cable has a full-size neutral (same gauge as the hots), which likely accounts for this. The electrician should verify neutral adequacy during installation.

Note: Existing daisy-chain wiring from the old switching box is NOT reusable --
      the old switching box and the new rack closet are on opposite sides of the
      facility. New conduit runs and individual home runs are required from each
      SmartPack channel to its fixture group. Each output channel has a 10A/120V
      internal breaker; the electrician determines wire size based on run lengths
      to fixture locations and the number of conductors sharing conduit (standard
      installation calculations). Panel-level demand calculation per CEC Rule 8-200
      is part of the electrician's permit process.

These devices draw power from the network switch via PoE and do not require dedicated electrical circuits.

Panel Load Summary

All loads fed from the new panel. This table will be updated as equipment is selected and loads are confirmed.

AV rack detail

Four circuits feed the rack closet (1x UPS, 3x amp). See Rack Plan – Electrical for the full circuit-by-circuit breakdown, outlet allocation, and amp breaker sizing notes.

The UPS is an online double-conversion unit (AC-DC-DC-AC topology), producing a clean sine wave – better for AV equipment than line-interactive or standby designs. It takes 120V input via a NEMA L5-20 receptacle (single-pole breaker, standard conductor sizing). Three amp circuits across two panel legs – the electrician distributes them to balance the load (two on one leg, one on the other). Amp receptacles are co-located with the UPS outlet (ceiling or low wall, depending on whether the rack closet ceiling is kept or removed). The distance from the panel to the rack closet receptacles is almost certainly within 20’, making voltage drop negligible.

The IT switch does not require an isolated ground or dedicated neutral – it is powered from a rack PDU on the always-on infrastructure circuit (same as the M4250). Additional RLNKs, if added, do not require additional panel circuits because they are downstream of the UPS.

Lighting dimmers detail

Both SmartPacks are wall-mounted in the rack closet. Each ETC SmartPack 12x1200W has a total dimming capacity of 14,400W (12 channels x 1200W). Two SmartPacks = 28,800W total capacity. However:

• With LED fixtures, actual draw per channel will be well under 1200W (likely 100-300W depending on fixtures). The SmartPacks’ full capacity will not be used.
• Panel wiring must support each SmartPack’s 60A / 240V single-phase hardwired feed (2-pole breaker per unit, 120A total for both).
• Actual fixture load will determine the true demand on the panel. The dimmer capacity is the ceiling, not the expected operating load.

See Lighting Plan for dimmer, fixture, and zoning details.

Kitchen SmartPack decommissioning

The existing kitchen SmartPack is being relocated to the South Gym. The electrician handles the disconnect as part of the relocation scope and permit – no separate permit or inspection is required for the removal itself. Orphaned kitchen circuits get capped off in junction boxes or pulled at the electrician’s discretion. A pre-relocation condition assessment is not needed: SmartPacks are built for heavy theatrical use, and a kitchen lighting circuit is light duty. If a channel has issues, it will show up during commissioning, and individual triacs are replaceable.

LED wall detail

Long-term, one or two LED walls will replace the projector (see Video Plan). LED wall power draw depends on panel area, pixel pitch, and brightness. Typical indoor LED panels draw ~200-500 W/m² at full brightness. The NovaStar VX4S processors are in the AV rack and already counted in the rack power budget. The LED panels themselves will need power at their mounting location, fed from this panel. A junction box is needed at each mounting location to transition from building wiring to Neutrik powerCON connectors (the standard power interface for LED panels). If two panels are installed at separate locations (Option B), two separate conduit runs are required – the panels would be at least 20’ apart.

Conduit for LED wall power and data will be run during the initial renovation to avoid retrofitting later, even though the wall itself is a long-term addition.

Panel Sizing

The panel size (bus rating and number of breaker spaces) depends on total connected load. Key unknowns that affect sizing:

• SmartPack input configuration (resolved: 60A / 240V single-phase per unit, 2-pole breaker)
• UPS input requirements (model TBD)
• LED wall size and power (long-term)
• Actual lighting fixture selection (determines real dimmer load vs. 1200W/channel capacity)

Working estimate

For planning purposes, this estimates the likely operating load (not the theoretical maximum of every dimmer channel at full capacity):

At 120V single-phase: 7,000W = ~58A, 15,500W = ~129A At 120/208V: proportionally lower current per leg

A 100A to 200A panel is a reasonable planning range, with the final size dependent on resolving the TBDs above. A 42-space panel would accommodate all foreseeable circuits with room for growth. Approximately 10-12 spaces are used (1x UPS, 3x amp, 2x two-pole SmartPack, 1-2x LED wall, 1-2x convenience), leaving ~70% spare – well beyond any 20-25% requirement.

Grounding & Bonding

The new panel uses the building’s existing grounding electrode system via the equipment grounding conductor in the feeder from the main panel. No separate grounding electrode is needed.

UPS ground isolation

The online double-conversion UPS creates a ground isolation boundary between the panel’s equipment grounding conductor and the regenerated ground reference downstream. This eliminates the need for:

• Dedicated rack grounding bus bar – the UPS isolates rack equipment from building mains ground, so a separate bus bar with chassis bonding is not required.
• Isolated ground (IG) wiring – the UPS provides equivalent isolation to IG circuits; no IG bus bar or IG-type receptacles are needed.

Dimmer-to-AV noise isolation

SmartPack dimmer circuits and the UPS are on separate branch circuits with no shared neutral, so forward-phase harmonic noise cannot travel to AV equipment via the neutral conductor. The only shared point is the panel bus, and the online double-conversion UPS rectifies and regenerates AC, stripping any upstream noise before it reaches rack equipment. No additional filtering or isolation is required between SmartPack circuits and UPS input circuits.

Ground boundary crossings

The UPS ground isolation boundary is crossed by three signal paths. Each uses differential signaling that rejects common-mode ground noise:

DMX cable shield grounding: Grounded at one end only (Paradigm ACP / transmitter end) per ANSI E1.11. The Paradigm ACP’s ground reference depends on its enclosure power source (TBD – ERn or DIN rail PSU) and the SmartPacks are on building ground – grounding the shield at both ends would create a ground loop. DMX is differential (RS-485), so the signal is unaffected as long as the shield is grounded at one end only.

M32R console ground loop: The M32R plugs into a convenience outlet (building ground) while the rack DL16 is on UPS ground. The AES50 cable shield bridges the two ground references. AES50 is differential digital signaling, so data integrity is not affected. Shield current could cause EMI in theory but is unlikely to be an issue in practice at the distances involved.

Wireless mic antenna grounding: Not applicable for the initial install – antennas ship attached to the receiver, so the antenna ground is the receiver chassis (UPS ground via RLNK, no boundary crossing). If remote-mounted antennas are added later, the coax shield would bridge UPS ground to the antenna mounting point’s ground reference, and CEC/NEC 810 antenna grounding requirements would apply. Revisit if remote antennas are needed.

Safety & Code Compliance

Emergency and exit lighting is on a completely separate system, unrelated to this panel or the SmartPacks. No SmartPack fault or AMX preset can disable it.

AFCI protection is not required. AFCI is a residential requirement under the Canadian Electrical Code and does not apply to commercial/institutional buildings. It would also be impractical here – Class D amplifier inrush current and SmartPack dimmer waveforms would cause nuisance trips.

Arc flash labeling is required on the new panel. Simplified labeling is sufficient for a sub-panel of this size – the electrician applies a standard arc flash warning label. A full arc flash hazard analysis is not needed.

Emergency disconnect is not required for the AV/lighting system. Emergency disconnects are for commercial kitchen equipment, HVAC, and industrial machinery. The panel breakers serve as the disconnect for this equipment. No separate panic switch accessible outside the locked rack closet is needed.

Conduit & Future-Proofing

Rack closet interior runs use EMT (metal conduit) affixed to the wall. Fiber runs are armored and wall-affixed (see Networking Plan).

All wire runs should be in conduit wherever possible, including low-voltage runs such as speaker wiring. The gymnasium ceiling will remain open (exposed structure) after construction, so conduit is visible and should be routed cleanly. Conduit should be stubbed from the rack closet to speaker rough-in locations while walls and ceilings are open during construction.

A dedicated conduit stub-out to a scorer’s table location at floor level is not needed – a scoreboard cart would be self-contained with its own power and data, using a convenience outlet and network drop.

Motorized blackout shades are not needed for the gymnasium – there are no windows.

Ventilation fan conduit and breaker space are out of scope for this plan – ventilation is part of HVAC.

Permits & Inspection

An Alberta-licensed electrical contractor handles the permit and coordinates with the Safety Codes Officer as part of standard practice. The electrician pulls the permit.

The relocated kitchen SmartPack requires a fresh inspection as a new installation – it is being relocated to a new panel with all new wiring downstream, so the entire installation will be inspected as new work.

Stamped electrical drawings from a Professional Engineer registered in Alberta are unlikely to be required. In Alberta, a licensed electrical contractor can design and install a sub-panel and branch circuits without P.Eng involvement – stamped drawings are typically only required for larger commercial projects. If the Safety Codes Officer flags it during the permit process, the electrician would engage a P.Eng at that point.

Open Questions

Panel & Service Entry

• Panel location in the room
• Is this a main breaker panel or a sub-panel with main lug only? What is the upstream feeder breaker size at the main distribution panel?
• Feed from main building service to this panel (wire size, conduit run, distance). Has a voltage drop calculation been performed for the feeder at full panel load?
• What is the main building service capacity, and does it have headroom for this new panel? The working estimate of 6,500-14,500W needs to be added to the building’s connected load calculation.
• What is the available fault current (AFC) at the main building panel, and does the new panel’s short-circuit current rating (SCCR) meet it?
• What size main breaker and bus rating? A 100A main in a 200A bus panel is different from a 200A main – the choice affects upstream feeder sizing.
• Is the upstream feeder breaker large enough to carry the full load including the future LED wall without being replaced?
• Does the panel location comply with CEC Rule 2-308 minimum working clearances (36“ depth, 30“ width, 6.5’ headroom)? Given SmartPacks are also wall-mounted in the same closet, do all three pieces of equipment simultaneously meet clearance requirements?

UPS & Rack Circuits

• What is the total VA load the UPS must carry? Most rack device wattages are still TBD – UPS cannot be specified until these are known.
• Where are the rack closet receptacles located? TBD – depends on whether the rack closet ceiling is kept or removed. If ceiling remains, L5-20 on the ceiling. If removed (open to gym structure above), L5-20 on the wall behind the rack.

LED Wall (Long-Term)

• LED wall power requirements (panel area, pixel pitch, brightness)
• What conduit size and quantity is needed for LED wall power and data? Routing path from rack closet to each candidate wall location?
• Should conductors be pulled into the LED wall conduit now, or left empty? If pulled now, what size accommodates the 1,000-5,000W range at that distance?
• How will open conduit stub-outs be sealed during the interim period to prevent water intrusion, pests, or combustion gas entry?
• Does the panel bus rating accommodate adding the LED wall load without upgrading the feeder from the main service?

Surge Protection

• Is a Type 2 surge protection device (SPD) warranted at the new panel? The online UPS already protects rack equipment downstream of it, but the amps and SmartPacks are on dedicated circuits without surge protection. Whether a panel-level SPD is needed depends on the building’s exposure to surges (lightning, utility switching, large motors) and whether a Type 1 SPD already exists at the main service entrance. Need to check with electrican.

Safety & Code Compliance

• Do lighting control scenes comply with minimum illuminance requirements for paths of egress under the Alberta Building Code? Is there a floor level enforced in AMX/DMX so a preset cannot go below code-required minimums?
• GFCI: the rack closet has an exterior wall – if insufficiently insulated, condensation could lead the Safety Codes Officer to classify it as a damp location, requiring GFCI on 15A/20A 125V receptacles. GFCI on a Class D amp circuit will nuisance-trip on inrush. Ask the electrician to confirm the classification during the permit process.
• Do the SmartPacks’ internal magnetic breakers (10A per channel) have adequate interrupting ratings for the available fault current at this panel? The electrician needs to calculate the AFC at the panel location and confirm the SmartPack’s SCCR meets it. Likely not an issue for a sub-panel on a moderate feeder run, but should be verified during the permit process. ETC does not publish the SCCR in their public documentation.

Permits & Inspection

• What inspection stages are required (rough-in before walls close, final after fixtures)? The gymnasium ceiling is open (exposed structure) so ceiling conduit is accessible post-construction. Wall rough-in still needs inspection before closing. Confirm stages with the electrician.

Conduit & Future-Proofing

• What are the conduit paths from the panel/closet to: projector (ceiling), N1115-WP wall plate (back wall), LED wall stub-out, speaker locations, lighting fixture zones?
• How many convenience outlet locations are needed for events? No prescriptive commercial code requirement (unlike residential outlet spacing rules) – this is driven by use cases. Consider caterer/vendor setup areas (along walls, near kitchen), portable production table location, and avoiding extension cords across the gym floor during events.

Notes

• Channels are NOT bridgeable on the 5.0 (bridging only available on the two lower-wattage models)
• The line-level through outputs allow daisy-chaining between amps that share the same signal, avoiding the need to split at the BLU-100 output. With three amps serving different roles (ceiling speakers, subwoofers, floor monitors), each amp likely needs its own BLU-100 output pair — through outputs are useful if any two amps share a feed
• Input parallel mode can drive both channels from a single input
• Input function “sub” mode could allow one amp to handle subs while another handles full-range

Comparison with RLNK-915R

The RLNK provides AMX-controlled per-outlet switching (essential for preset-driven power sequencing). The PDS provides more outlets with built-in surge protection and local sequencing, but no remote control. They could be used together — e.g., RLNK for AMX-controlled devices, PDS for always-on or locally-sequenced loads.

RF

Audio Outputs

• Frequency response: 50 Hz - 18 kHz
• S/N ratio: >105 dB (A-weighted)
• THD: <0.5% at 1 kHz

Audio Level Notes

The outputs are line level, not mic level. Even the lowest setting (-6 dBV balanced) is well above mic level. Downstream devices (BLU-100, DL16, splitters) must accept line-level inputs. This resolves the open question in audio.md about receiver output level – passive mic splitters designed for mic-level signals are not suitable. Use line-level splitting (active buffer, or simply patch the XLR outputs to the appropriate line-level inputs on the BLU-100 and DL16).

ETC Paradigm ACP

• Role: Lighting controller for both gymnasium (0-10V) and event (DMX512) layers
• Model: Paradigm Architectural Control Processor (Mk1 or Mk2 – see generation notes below)
• Mount: TBD – either ERn wall-mount control enclosure or DIN rail enclosure (see enclosure options below)
• Dimensions: Processor module is a single-width card (enclosure-mount) or compact DIN rail unit (P-ACP-D)
• Power: ERn: powered from enclosure bus (own AC input). DIN rail P-ACP-D: external 24V DC PSU.

Generation Notes

Either generation supports the South Gym’s requirements (PSAP, DMX512A output, sACN output for 0-10V via Response Gateway, button stations, NV presets, LightDesigner). The South Gym uses ~24 DMX channels + a handful of 0-10V zones – well under the Mk1’s 1,024-channel limit.

Enclosure compatibility: The Mk1 and Mk2 use different backplane connectors. A Mk1 P-ACP cannot mount in a Mk2-era ERn, and vice versa. If the building has an existing Mk1-era ERn with spare capacity, use a Mk1 P-ACP. If purchasing a new ERn, it ships with Mk2 backplane and requires a Mk2 P-ACP-E. Do not mix generations within a single enclosure. The P-ACP-D (DIN rail) is Mk2 only.

Enclosure Options (TBD)

The Paradigm ACP is not rack-mounted. The enclosure choice is an open question:

Either option works for the South Gym. The DIN rail approach is cheaper but forces Mk2. If reusing an existing Mk1 ACP from facility inventory, the ERn is required.

Outputs

RS-232 Protocol (PSAP – Paradigm Station Access Protocol)

• Format: CR-terminated ASCII commands (0x0d).
• Protocol name: PSAP (Paradigm Station Access Protocol)
• Connection: EXB-COM2 port 1 in the South Gym rack

PSAP Command Reference

Full PSAP command syntax and parameters are documented in the ETC Paradigm configuration manual (see Reference Documents below).

AMX Integration Notes

• Preset-based control: AMX recalls Paradigm presets via PSAP. Each preset can control both 0-10V zones (gymnasium) and DMX channels (event SmartPacks) simultaneously.
• Zone override: After recalling a preset, AMX can override individual zones via PSAP for fine-tuning (e.g., adjusting a single dimming zone without changing the full preset).
• Poll-based watchdog: The Paradigm does not have a built-in heartbeat like the DFD 2322DMX. AMX must periodically send PSAP status queries and flag a fault if no response is received.
• Priority system: The Paradigm assigns priority levels to each input source. Button stations are configured at a higher priority than the RS-232 serial input, so physical wall switches always take precedence over AMX commands. When the button station input releases (e.g., an “off” press or timeout), serial control resumes.
• Single serial link: One RS-232 connection on EXB-COM2 port 1 controls both lighting layers – no second serial device or port is needed.

Fallback Behavior

• AMX down: Presets stored in the Paradigm’s non-volatile memory. Gymnasium presets are recalled from button stations (independent of AMX and network). Event presets can be recalled from button stations if configured.
• Power loss: The Paradigm restores its last state from non-volatile memory on power-up. No preset data is lost.
• Alternative: If the Paradigm’s DMX output proves unsuitable for SmartPacks, the DFD 2322DMX can be reinstated as an RS-232-to-DMX bridge on EXB-COM2 port 2, restoring the original two-serial-link architecture.

ETC Response 0-10V Gateway (RSN-LV-R3)

• Role: Converts sACN from the Paradigm ACP to 0-10V control signals for gymnasium fixtures
• Model: RSN-LV-R3 (current production)
• Part number: 4267A1202
• Outputs: 24 channels of 0-10V sink control
• Sink current: 100 mA max per output (sufficient for ~50+ typical LED drivers per channel at <2 mA each)
• Input: sACN (streaming ACN) over Ethernet, or DMX512 (5-pin XLR). Dual-input with configurable precedence.
• Mount: DIN rail (standard 35mm)
• Dimensions: 4.13“ x 9.41“ x 1.22“ (105 x 239 x 31 mm)
• Weight: 1.38 lb (0.62 kg)
• Power: 12-24 VDC via external PSU (ETC PS-DIN24, ~$80)
• Configuration: ETC Concert software over Ethernet, or onboard 4-button interface
• Features: UL 924 listed for emergency luminaires, contact closure input for emergency-level activation, configurable dimming curves per output

Notes

• The gateway is standalone – it does not need a DRd, ERn, or any other ETC enclosure. It mounts on any standard DIN rail.
• Can be mounted near the Paradigm ACP (rack closet) or near the gymnasium fixtures to keep 0-10V cable runs short. Only needs Ethernet and 24V DC power at its location.
• The 0-10V outputs use the sink protocol (ANSI/IES TM-23): the LED driver provides the 10V reference, and the gateway sinks current to dim. This is compatible with virtually all 0-10V LED drivers.
• The R3 revision (Nov 2023) adds per-output electrical isolation, preventing leakage voltage from one driver from affecting others.
• ETC also offers optional DIN rail enclosures (DIN14, DIN28) if a NEMA-rated box is needed.

DFD 2322DMX

Status: alternative/spare – not in the primary signal chain. The Paradigm ACP now drives the SmartPacks directly via its built-in DMX512A output. The 2322DMX is retained as a documented fallback if the Paradigm’s DMX output proves unsuitable. See ETC Paradigm ACP.

• Role: RS-232 to DMX512 bridge (alternative – see status note above)
• Control: ASCII commands via RS-232 from AMX
• Output: DMX512, ESD-protected EIA-485 (LT1785), opto-isolated, bidirectional
• Presets: 20 onboard presets with individual fade times (default 2 seconds per preset)
• DMX connectors: Gold-plated male/female 5-pin XLR (Neutrik D-1 series)
• Dimensions: 8.25“ x 1.7“ x 6.5“
• Weight: 3.3 lb
• Power: 100–120VAC 50/60Hz, 12W (208–240V optional)
• Indicators: Power LED (red), DMX signal LED (green), MIMIC LED (green)
• Address switches: 3-digit thumbwheel for DMX start address / channel of interest
• Note: Must be in transmit mode (M0) for AMX to control lighting. Receive mode (M1) is for recording presets from an external DMX console. Mode is stored in non-volatile memory.

RS-232 Protocol

• Format: Plain ASCII commands terminated with <CR> (0x0d). Case-insensitive. Spaces optional.
• Response: OK on success, Error on failure.
• Connectors: Front panel DB-9M or rear panel 3-pin female XLR (only one active at a time).
• Buffer: 256-byte circular receive buffer.

Command Reference

• Channel lists support + and - for ranges: C 10 – 15 + 25 + 500 @ 255 T 7<CR>
• @ and L are interchangeable for setting levels.
• After a preset is recalled, individual channels can be adjusted live. If any channel is changed, ? P reports preset 0 (modified state).

AMX Integration Notes

• Heartbeat for watchdog: Enable H 1 so the 2322DMX sends . every second. AMX can monitor for this character to detect a dead serial link — this answers the monitoring question raised in control.md and lighting.md.
• Preset recall is the primary AMX command: P ##<CR> with optional fade override. Simple to implement in NetLinx.
• Query support: AMX can poll ? P to confirm which preset is active after a recall.
• No IP option: RS-232 only — requires a serial path from the NX-4200 to the South Gym (see control.md open questions).

• Protection: Automatic thermal overload cut-out, electric brake to prevent coasting
• Limit switches: Pre-set, adjustable; automatically stop surface in up and down positions
• Roller: Rigid metal

Control

The screen has built-in LVC (Low Voltage Control) – confirmed by the low-voltage cable running to the Decora-style three-position wall switch (up / stop / down). With LVC, the wall switch sends a low-voltage signal to the motor module rather than switching line voltage directly. AMX can trigger raise/lower by closing a dry contact on the LVC input via an EXB-REL8 or IP2CC-P relay.

Available control options for this screen (for reference):

Notes

• The control method determines how AMX interfaces with the screen. If equipped with LVC or Video Projector Interface, AMX can trigger raise/lower via a low-voltage signal or dry contact relay (see EXB-REL8 and IP2CC-P entries). If equipped with an SCB-100, AMX can control via RS-232 or Ethernet (via NET-100). The standard 120V switch requires a relay to automate.
• Extra drop (additional black material above or below the viewing area) is available to lower the picture area beyond the standard 2“ black drop. Maximum total surface height including picture area is 13’.
• All Da-Lite surfaces are GREENGUARD GOLD Certified.
• UL Listed.

Open Questions

• What is the installed drop distance from the case to the bottom of the viewing area? Is there extra drop configured beyond the standard 2“ at top?

South Gym — Information Still Needed

Items you need to track down: site measurements, equipment identification, decisions, and questions for contractors. Organized by what kind of action is required.

Items marked with → are unlocked by their parent — once the parent is answered, those sub-items can be looked up or derived without additional site work.

Design-phase details (AMX programming logic, DSP preset parameters, touch panel UI layout, commissioning procedures) are tracked in the open questions sections of each plan file and are not duplicated here.

Waiting to Receive

• DWG files and facility drawings (requested) — unlocks DIALux evo lighting calculations (imports DWG natively) and EASE Focus 3 speaker coverage modeling (import as DXF background). Also provides accurate cable run distances and conduit path planning.

Site Visit / Physical Measurement

These require being physically present in the space.

Room

• Floor dimensions (length x width) — unlocks photometric calculations, speaker coverage modeling, zone layout, cable run estimates. May be answered by DWG files once received.
• Ceiling height at speaker and fixture mounting points
• Structural mounting points in the exposed ceiling (for speakers and light fixtures)
• Will the radiative heating system be removed with the new air handler? Will the brick wall be framed out or get drywall directly on it? (affects surface-mount vs. flush-mount for wall-mounted equipment)
• Wall and floor surface materials — concrete with brick finish up to 10’, wood paneling above; dark green rubber gym floor; no acoustic treatments
• Existing acoustic treatments, operable walls, or large glass surfaces — none of the above; all walls fixed, no windows
• HVAC units, bleachers, or large surfaces causing flutter echo — no bleachers; no in-room HVAC units; external air handler with supply/return vents; ceiling-mounted circulation fans; flutter echo TBD on-site
• Is there a fixed stage/speaking position, or does it move by event type? — fixed at front of room, under projection screen / future LED display(s)

Projector

• Make and model (read the label on the unit) — unlocks everything below:
  • → Lumens, native resolution, remaining lamp life (from spec sheet)
  • → Warm-up and cool-down time; mandatory cool-down period (from manual)
  • → Auto-wake feature that could conflict with AMX power sequencing (from manual)
  • → RS-232 command protocol for power on/off/status (from manual — currently blocking AMX programming in control.md)
• Measured throw distance from projector lens to screen (site measurement)
• Does the current image fill the screen properly? (site observation)
• Is there a horizontal offset between projector and screen requiring keystone correction? (site observation)

Projection Screen

• Bottom edge height when fully lowered — do audience members at the back have an unobstructed sightline?
• Installed drop distance from the case to the bottom of the viewing area (any extra drop beyond standard 2“?)

Existing Lighting

• How many existing fluorescent fixtures, and what type? — needed for demolition planning and may inform new zoning layout
• Can the existing ~8 daisy-chain groups be mapped to inform the new zoning layout?
• What happens to the existing dry-contact switching box once decommissioned?

Rack Closet

• Exact interior dimensions — unlocks everything below:
  • → Can a 42U rack, two wall-mounted SmartPacks, and required electrical working clearances all fit?
  • → On which wall(s) will SmartPacks be mounted? Dimensioned layout showing rack footprint, SmartPack positions, and clearance zones
  • → Usable wall area for two SmartPacks while maintaining code-required working clearances
  • → CEC Rule 2-308 clearances with SmartPacks in the same closet (electrician question)
• How do SmartPack output wires exit the units (top/bottom/side), and is there clearance for conduit sweeps? (can be partially answered from SmartPack installation manual)
• Where are the rack closet receptacles located? Depends on whether the closet ceiling is kept or removed
• Who has physical key access to the closet?

Cable Run Distances

Several of these are blocked by decisions that haven’t been made yet. Measure the ones you can; the rest will follow.

• Rack to back-wall N1115-WP wall-plate encoder
• Rack to ceiling-mounted NMX-DEC-N1222A decoder (at projector)
• Rack to M32R floor drop(s) — blocked by floor drop location decision
• Rack to AMX touch panel location(s) — blocked by touch panel location decision
• Rack to farthest speaker location — blocked by speaker placement design
• Rack to farthest fixture location — blocked by fixture layout design
• Rack to each candidate LED wall location — deferred with LED wall decision
• All runs expected to be well under 100m Cat 6A max — confirm on-site

Conduit Paths

These will largely be determined by the electrician based on the cable run distances above and building structure. Confirm routing during the permit/design process.

• Rack closet to projector/decoder (ceiling)
• Rack closet to N1115-WP wall plate (back wall)
• Rack closet to LED wall stub-out(s) — deferred with LED wall, but conduit should be run during renovation
• Rack closet to speaker locations — blocked by speaker placement design
• Rack closet to lighting fixture zones — blocked by fixture layout design
• Relay wiring path from rack to screen motor controller (PoE Ethernet or low-voltage wire — conduit needed either way)
• How many conductors will share each conduit from the closet to fixtures? (affects conduit fill derating per CEC Table 5C) — blocked by fixture layout and zone count

Equipment Identification / Selection

Needs to Be Decided

• Speaker model selection — unlocks impedance, sensitivity, amp sizing validation, wire gauge, breaker sizing, zone wiring plan. Blocked by room dimensions (for coverage modeling).
• Gymnasium lighting fixtures — blocked by room dimensions (for photometric calc). Once selected, unlocks:
  • → Circuit sizing and wattage
  • → Energy code (NECB) compliance check
  • → IES photometric layout
• Event layer fixtures — types per zone (field, perimeter/wall-wash, stage). Once selected, unlocks:
  • → Forward-phase dimming compatibility confirmation
  • → SmartPack minimum load threshold check
• Subwoofer: needed or not? If yes, placement and low-frequency extension target (80 Hz speech vs. 40-50 Hz music)
• Floor monitor: needed or not?
• Paradigm ACP enclosure type — ERn wall-mount (Mk1 or Mk2) or DIN rail P-ACP-D (Mk2 only). Once decided, unlocks:
  • → Power requirement and feed method
  • → Physical mounting location
• Response 0-10V Gateway mounting location — near ACP (rack closet) or near gymnasium fixtures (shorter 0-10V runs)
• ClickShare model confirmation (CX-20 or similar) — once confirmed, unlocks:
  • → Verify ClickShare + LP10 fit side by side on a single 1U vented shelf (from spec sheet dimensions)
• UPS model and sizing — blocked by device wattages (need equipment selection first)
• Mac mini rack shelf — Middle Atlantic makes Mac mini-specific mounts; which one?
• SFP+ transceivers for M4250 fiber uplink (single-mode LC, wavelength, reach) — depends on fiber type and distance to upstream switch

Rack Layout

• Horizontal cable managers (1U) at any positions?
• Vertical cable managers for rack sides?
• Dedicated equipment grounding bus bar? (can be checked from ERK-4025 spec sheet)
• Rack elevation drawing (to scale) as installation deliverable?
• At 23-1/2“ usable depth between rails, verify all devices fit with rear cabling accessible — all fit; Pro-LITE 5.0 is deepest at ~20.25“ total (17.25“ chassis + connectors + bend), leaving ~3.25“ clearance; DL16 is only ~12.6“ total; SVSi frame is 5.04“ chassis
• Front or rear rack door? — no rack doors
• Slide rails for UPS, amps, or DL16? — no slide rails

Decisions Needed

These require stakeholder input or a design choice.

Display

• LED wall: Option A (single large wall) vs. Option B (two smaller panels) — deferred, no time pressure
• LED wall: candidate mounting wall location(s) — deferred, depends on A/B
• LED wall: physical dimensions (width x height) — deferred, depends on A/B + viewing distances + pixel pitch
• Digital scoreboard software/system — deferred until LED wall is selected
• Rack PC operator access — monitor in rack closet, KVM extender, VNC/remote desktop?

Audio

• How many discrete speaker zones with independent level control? — unlocks amp usage plan, BLU-100 output assignment, wiring design
• Antenna type for wireless mics (omni paddle vs. directional log-periodic) given metal ceiling
• Antenna mounting location — remote from rack closet or at rack?
• Battery management plan for wireless mics (rechargeable vs. disposable, charger location)
• M32R floor drop: single fixed drop or two locations (either side of room)?
  • → Floor drop type: flush floor box rated for gymnasium floor traffic? (follows from location decision)
• M32R umbilical contents: Ethernet + AES50 + IEM returns + power? Separate cables or combined?
• Is there budget or willingness for acoustic treatment (hanging baffles, fabric panels)?

Lighting

• How many gymnasium zones/circuits? “Half Gym” split needed?
• How many event zones/circuits (up to 24 available)?
• Minimum dim level for events — is 10% sufficient, or need below 5%?
• Tunable white (variable CCT) needed, or single fixed CCT acceptable?
• Paradigm button station locations (near main entrance? multiple?)
  • → Should a button station include event layer preset buttons for non-technical fallback? (follows from location decision)
• AMX touch panel count and locations — also affects networking drops and cable runs
• Auto-off after inactivity / occupancy sensing needed? (almost certainly not — confirm)
• Time-based scheduling needed (e.g., “School Gym” at 7 AM, “Off” at 10 PM)?

Control

• What does “system off” mean operationally? (all RLNK off + amps on dedicated circuits + lights off + projector off + screen raised? Or everything de-energized? Or standby?)
• Relay wiring path for screen control — PoE IP2CC-P via Ethernet, or REL8 via low-voltage wire?
• Volume control on touch panel — single master, per-zone, or per-source? (per-zone only relevant if zone count is decided)
• Does the Mac mini need a graceful shutdown signal before RLNK power is removed? (can be tested)
• Budget range for the overall project

Networking

• VLAN assignment for rack PC and ClickShare (SPACnet VLAN 5 for user device discovery, or split?)
• Wall plate locations and quantities (beyond the known back-wall N1115-WP)
• Cable labeling standard (Brady, P-touch, heat-shrink) and naming convention
• School division AP cabling requirements — coordinate

Electrician Questions

Bring these to the electrician during the permit/design process. Many of these form a dependency chain — the electrician will work through them in order.

New Electrical Panel

• Panel location in the room
• Main building service capacity — headroom for this new panel? (working estimate 6,500-14,500W)
• Available fault current (AFC) at the main building panel — unlocks:
  • → Does the new panel’s SCCR meet the AFC?
  • → SmartPacks’ internal 10A magnetic breakers — adequate interrupting rating? (Code & Safety)
• Bus rating and main breaker sizing (100A in 200A bus vs. 200A main — affects upstream feeder)
  • → Main breaker panel or sub-panel with main lug only? Upstream feeder breaker size?
  • → Feed from main building service: wire size, conduit run, distance. Voltage drop calculation?
  • → Is the upstream feeder large enough for the future LED wall without being replaced?
• CEC Rule 2-308 working clearances — do SmartPacks in the same closet still allow compliance? (blocked by rack closet dimensions)

Circuits & Wiring

• Amp breaker sizing — blocked by speaker impedance (blocked by speaker selection)
• SmartPack circuit requirements at mounting location (2x 12 channels @ 1200W/channel = 28,800W total capacity)
• Gymnasium fixture circuit sizing — blocked by fixture selection (count and wattage)
• Paradigm ACP power requirement — blocked by enclosure choice
• Response 0-10V Gateway power (18-24 VDC via ETC PS-DIN24) — known spec, just needs location and outlet
• Forward-phase dimmers produce harmonics on neutral — do shared neutrals need upsizing per CEC Rule 4-024? (event layer only)
• Convenience outlet locations for events (caterer/vendor areas, production table, avoiding floor extension cords)

Code & Safety

• Type 2 surge protection device at the new panel? (UPS protects rack gear, but amps and SmartPacks are on unprotected dedicated circuits)
• GFCI: exterior wall in rack closet — if classified as damp location, GFCI on 15A/20A receptacles. GFCI on Class D amps will nuisance-trip on inrush. Confirm classification during permit
• Minimum illuminance for paths of egress under Alberta Building Code — enforce as floor in AMX/Paradigm programming?
• Emergency or exit lighting code requirements (Alberta Building Code / NBC)?
• Inspection stages (rough-in before walls close, final after fixtures) — ceiling is open/exposed, but wall rough-in still needs inspection before closing
• Single electrical permit for full scope (SmartPack relocation, new panel, home runs, gymnasium fixtures, Paradigm, button stations)?
• Asbestos survey on existing fluorescent fixture bodies, ballasts, or ceiling materials before demolition?
• PCB content in existing ballasts (pre-1979) requiring hazardous waste handling?

HVAC / Ventilation

• Rack closet ventilation approach: passive grille into return air plenum, or active fan?
• Total rack heat load in BTU/h — blocked by device wattages (need equipment selection first)
  • → SmartPack heat output added to closet ventilation sizing (can be looked up from SmartPack specs)
  • → Realistic sustained amp operating scenario for sizing (blocked by speaker impedance)
• Static pressure characteristic of the return air duct — passive grille into pressurized plenum could cause reverse airflow
• Has the HVAC contractor confirmed the return duct has capacity for the additional rack closet heat load?

LED Wall (Deferred — No Time Pressure)

These can wait until the LED wall decision is being actively evaluated. Most are unlocked by selecting a manufacturer/model.

• Minimum and maximum viewing distances from candidate walls (site measurement)
  • → Pixel pitch for those distances (and whether it produces native 1080p at the intended size)
• Wall construction at candidate locations (masonry, steel stud, wood frame); structural capacity confirmed?
• Select LED panel manufacturer/model — unlocks everything below:
  • → Anticipated total weight of panels + mounting structure; stamped structural analysis needed?
  • → Ceiling clearance above panel for mounting frame; conflicts with joists, HVAC, catwalks?
  • → Peak power draw per m^2 at max brightness; single circuit or multiple?
  • → LED panel power supplies: internal or external/rack-mounted?
  • → VX4S signal protocol to panels (Ethernet, fiber, proprietary); max cable run length
  • → Number of data cables VX4S requires for the panel array; conduit capacity at wall
  • → Front-serviceable or rear-serviceable panels? Rear clearance needed?
  • → Manufacturer’s recommended spare module inventory and storage location
  • → On-site warranty service and response time
  • → Ball-impact resistance rating; polycarbonate overlay needed?
  • → Horizontal viewing angle; serves spectators at extreme lateral positions?
• Distance from each candidate wall to new electrical panel; conduit routing including fire-rated penetrations (site measurement)
• Ambient illuminance at display wall with house lights on; panel brightness sufficient? (blocked by lighting design)
• Should LED wall conduit have conductors pulled now, or left empty?
• How will open conduit stub-outs be sealed during the interim (water, pests, combustion gas)?

Wireless Frequency Coordination

See audio.md — Wireless Frequency Coordination for the full regulatory analysis and recommended operating configuration.

• Local UHF TV channels for Sherwood Park — 5 UHF stations in Edmonton market documented in audio.md
• ISED regulatory compliance check — Band 6UA (626-698 MHz) is mostly PROHIBITED in Canada (600 MHz auction). Only the 652-663 MHz duplex gap remains legal. Both receivers should be restricted to band 5UA or 5US. See audio.md for details.
• Will both ACT-727a receivers operate simultaneously with wireless systems in adjacent spaces (auditorium)? — not a concern; a few hundred feet through concrete/brick walls, signal well below noise floor
• With 4 wireless channels (2x ACT-727a), is that sufficient for the largest events? Any wireless instrument transmitters or IEM packs sharing the frequency pool?
• Worst-case distance from rack closet to farthest transmitter location — reliable range without remote antennas?
