AVBASE v2

ABOUT AVBASE

A knowledge base for AV rooms, as a chat. This one is the Jackpot Room: a corporate briefing room with a documented AV install, and a senior tech who has read all of it. Ask about signal flow, gear, routing, or what's broken. Type it or say it.

How it behaves

Answers from the room's documents only. It will not invent gear it can't see on the patch sheet.
Pushes back. Ask for something this room can't do safely and it says why, then offers what works.
Flags inference. When it reasons past what's documented, it tells you that's what it's doing.

Fictional venue

All gear, routing, and show details are placeholders authored for this demo, not a real venue, equipment, or client work.

JACKPOT ROOM: GEAR

What you're looking at: a sanitized install, fictional model names standing in for the industry-standard gear each one is based on.

Fadewell FC-16: digital console (FOH)

Channels: 48 in · 16 mixes · 8 matrices · 2 stereo masters (A = house, B = broadcast)
I/O: Local In 1–16 / Local Out 1–8 at the desk · Lattice network audio
Extras: 16-ch gain-sharing automixer · onboard USB recorder

Veltrix wireless: 16 channels

Rack: 4× VX-4 four-channel receivers, tech closet
Mics: 8× VB-1 lavs (ch 1–8) · 8× VH-1 handhelds (ch 9–16)
Antennas: 2 house paddles + 1 per breakout, through an AC-2 combiner

Stage & lectern

Lectern: 2 lectern mics (ch 29–30) + lectern PC on a DI (ch 31–32), all four on one Lattice IO-4 mounted inside the lectern body. One network cable to a stage-lip floor box; moving the lectern repatches that cable and nothing at the desk.
Floor boxes A / B: 4 XLR in each (ch 41–48), two Lattice IO-2s per box. The preamp is in the endpoint; gain is remote from the console strip.
Analog stage box: 16-channel passive copper box at the stage end. SB 1–8 standing-patched to ch 33–40; SB 9–16 spare. See Inventory.

Sonaris PA

House: LN-6 hangs of 4 per side (biamped, 2 zones each) · LNS-12 sub · 2× PN-10 delays
Breakouts: 6× CX-8 ceiling boxes per room, mono distributed
Drive: SP-412 (house) / SP-26 (breakouts) system processors · 5× DA-4 four-channel amps

Lattice: the audio network

What it is: the room's audio-over-IP protocol. Audio, device control, and clock all ride one flat network on the tech-closet switch. A channel here is a subscription, not a cable.
Endpoints: IO-2s in the floor boxes · IO-4 inside the lectern · Lattice VS (virtual soundcard) on every PC source
Reach: everything but the analog stage box: wireless, floor boxes, lectern, PCs, console to processors, and the broadcast feeds

Playback, meets & recovery

Audio PC: one FOH machine, three Lattice VS pairs on their own channels: Z-Play, cue-playback software for walkup, stingers and cued audio (ch 21–22) · the announcement player, fired from ButtonControl, a button pad that triggers the clip but carries no audio itself (ch 23–24, house-only) · bg music on the machine's main out (ch 25–26)
Meets: 2 conference PCs, signed in and muted from the MeetControl panel
Recovery: UPS at desk + closet · Bexley CM-20 portable rig with its own snake and wedges

SIGNAL FLOW: JACKPOT ROOM

Console inputs (Fadewell FC-16)

Ch 1–8 / 9–16: Veltrix lavs / handhelds, over Lattice
Ch 17–20: utility PCs A–B (Lattice VS)
Ch 21–26: Audio PC: Z-Play cues · announcements (house-only) · bg music
Ch 27–28: remote-meet A / B returns
Ch 29–32: lectern: 2 mics + lectern PC, one IO-4 inside the lectern
Ch 33–40: analog stage box SB 1–8 (the copper path)
Ch 41–48: floor boxes A / B (Lattice IO-2s)

Stems & masters

Mixes 1–8 feed the house PA (wireless, PCs, playback, meets, stage, lectern), summed on Stereo A; Mixes 9–16 mirror them to the broadcast master, Stereo B. Announcements are house-only by design.

Matrices

Matrix 1 / 2: mains L / R
Matrix 3: subs (music & playback only, never mics)
Matrix 4: delays (mono sum)
Matrix 5 / 6: remote-meet mix-minus sends
Matrix 7 / 8: breakout rooms 1 / 2

PA chain: house

Matrix 1–4 ride Lattice to the SP-412 processor, then out analog in-rack to the DA-4 amps → LN-6 hangs (upper and lower zone per side), the LNS-12 sub, and the PN-10 delays.

PA chain: breakouts

Matrix 7 (breakout 1) and Matrix 8 (breakout 2) ride Lattice to the shared SP-26 processor, 3 outs per room → DA-4 #4 and #5 → six ceiling CX-8s per room, two boxes jumped per amp channel. The breakouts have no local inputs, patch points, or controls; both rooms are driven entirely from FOH.

Everything is patched over Lattice except the analog stage box, the wired last resort if the network dies.

EXTRA INVENTORY: STOCK

Not part of the install. What's on the shelf when a show needs more than the room gives you.

Copper: the analog stage box

16-channel passive box at the stage end, tied to FOH on an analog multicore. Sends labeled SB 1–16; the room standing-patches SB 1–8 into Local In 1–8, arriving as ch 33–40.
SB 9–16 are spare tails: live copper at the stage with no home at the desk. Local In 9–16 are free, so an event needing more wired inputs just patches them.
Returns RTN 1–4 come from Local Out 1–4, normally wedge feeds, but usable for any console-to-stage send.
The only audio path in the room that needs no network at all.

Portable rig

Bexley CM-20 20-channel analog mixer · 75' portable snake, 12 send / 4 return, with its own stage box
4× self-powered floor wedges (they double as the portable rig's PA) · 2× speaker stands
Column + sub playback system · 4× mini self-powered backstage monitors

Mics & stands

Wired dynamics: 5× vocal, 5× instrument, 1× kick drum · 3× rim-mount tom mics (integrated hoop clip, no stand needed)
Stands: 4× tall tripod, 4× medium tripod (all eight boom-armed), 2× straight round-base, 4× small desktop
~20 assorted mic clips (stand clips, no hoop mounts) · 2× guitar stands · 1 DJ table

DI & cable

DIs: 2× Lattice-enabled, 2× passive PC/laptop, 2× stereo, 2× mono · 2× ⅛"-to-stereo-¼" adapters · 4× XLR M-M and 4× XLR F-F turnaround barrels
XLR: 6× 10', 6× 25', 4× 50', 2× 100'
6× ¼"-to-¼" · 4× ¼"-to-XLRM · 4× ¼"-to-XLRF · 10× IEC · Edison 6× 25', 6× 50', 4× 100'

SAMPLE SHOWS: PICK ONE

Fictional client briefs. Open one and hit Set up this show to hand it to the room as a job.

Have a show doc of your own? Attach it with the paperclip and ask how to set up the room. Or send the first brief above as a PDF to watch the room read a document instead of a button.

HOUSE AL R

The Jackpot Room

New here? Start with one of these, or ask the room anything in the box below.

I've never done AV before and I have to run an event in this room. Where do I start? What feeds the house left PA? A lav is dropping out in breakout 1 but it's fine in the main room. Why? What still works if the Lattice network goes down mid-show?
