 +===== Network switches =====
 +There are two switches in the rack, for powering AV-related escapades:
 +  * 1x 48 port 1 Gbps switch ([[https://ip.hackeriet.no/dcim/devices/76/|lydrack-sw2]]), for high-throughput applications (video, etc.) with uplink to hackeriet-sw
 +  * 1x 24 port 100 Mbps switch ([[https://ip.hackeriet.no/dcim/devices/74/|lydrack-sw]]), for low-throughput PoE applications (audio, DMX, etc.) with uplink to lydrack-sw2
 +
 +See netbox for further information.
 +
 +===== Lydrack PC =====
 +There is one PC in the audio rack, aimed at powering AV projects:
 +https://ip.hackeriet.no/dcim/devices/77/
 +
 +It has the following AV-related connections:
 +  * 1x Dedicated USB audio-card (Focusrite top-of-rack) connected to Aux send 1+2 on the mixer, for audio processing (e.g. LedFX)
 +  * 1x HDMI connection pulled to the projector in the roof
 +  * 3x UNUSED MiniDP ports for further projection units
 +
 +For display capabilities, see the project [[infra:ndi]].
 +
 +The PC runs the following software:
 +  * LedFX
 +  * TODO: music player daemon
 +  * TODO: shairport-sync (AirPlay)
 +  * TODO: Materix controller
 +  * TODO: Chromecast-MQTT bridge
  
 +Anything marked "TODO" is currently running on the "hack-radio" project pi. It is supposed to be moved to the lydrack-PC; please reach out to 404'd if you want to help.
