CRJ700/900 audio system
Okay folks, here's a head scratcher for you. I've asked captains, check airmen, and some maintenance folks, and haven't gotten an answer.
Circuit breaker 2V2, on the DC Essential bus, behind the F/Os flight case, is a 5 amp circuit breaker called "AUDIO PILOT"
This breaker is part of the audio system but not in the audio/visual indicating system (not the DCU power), and does not control the capt, f/o, and ovserver panel.
Anyone know what this is?

got your answer.... this breaker along with 1q6 (fo) provide power to the audio ctrl unit. pulling 2v2 should disable the ability to use pilot side audio functions.

CB's 1Q6 (CA) & 1Q7 (FO) power associated audio from the BATT Bus. In theory you would have to lose both busses to lose CA & FO audio power.
The observer audio has two breakers as well: 2H4 & 1Q8
