Beyla
Beyla
Beyla is the music server that powers KNOB, Noisebridge's 24/7 internet radio station. It's a small hexagonal mini PC sitting on top of the primary audio amplifier in the RNA Lounge -- the one with MC Escher on top (little green duck, gold chain, knitted cap).
Finding and Turning On Beyla
Beyla lives in the RNA Lounge, upstairs. Look for the amplifier with the green rubber duck on top -- that's MC Escher, and Beyla is the small hexagonal box sitting on the amp.
Beyla has a fancy little LED stripe light that indicates it's on. If Beyla appears to be off, look for a small round button on its side. Press it to power on.
Give it a minute to boot and the stream should come back up automatically.
Physical Audio Distribution
Beyla's 1/8" output jack is split three ways. Each output is converted to balanced audio over ethernet via an audio balun (RCA → ethernet cable → RCA), allowing the signal to travel cleanly over long cable runs to amplifiers distributed around the space.
The three amplifiers:
| Amp | Location | Notes |
|---|---|---|
| Primary (MC Escher) | RNA Lounge, on this amp's top | Beyla sits directly on top of this one. MC Escher (RDG) is permanently affixed to the amp. |
| RNA Lounge / Stairs | On top of the old NB podium, top of the stairs | The FM transmitter lives inside the podium body; the amp sits on top. |
| Hallway | Next to the kitchen, across from the Electronics Lab door |
Volume is controlled independently on each amplifier — each area sets its own level.
Technical Stack
- Liquidsoap -- audio routing, scheduling, and mixing engine
- Icecast 2 -- streaming media server
- Custom web dashboard -- zero-dependency Python HTTP server for now-playing info
The system uses a priority-based fallback chain: live DJ input always takes precedence, then scheduled programming, then a SomaFM internet radio fallback if all local sources fail.
