Is that subpanel just for your audio equipment:smile:
Yep. A 50a breaker in my main panel feeds this panel via 6/3 NM. The breakers are all 15a 1/2-space GE's. I used this panel because of the offset location of the guts, which gave me room for a 4p 25a contactor I had laying around.
This contactor allows the pre/pro's 12v switched output to control four of the circuits. These feed (1) the switched electronics, which don't need standby power, (2) the stereo amplifier, (3) the five-channel amplifier, and (4) the pair of subwoofer amplifiers.
Two of the unswitched circuits supply (1) the unswitched electronics, which have clocks and/or memories, and (2) the projector. The remaining two circuits are slated for lighting if and whenever. There are two more 3-gang holes above the receptacles.
By the way, also inside the panel is a 12v reed relay that is fed by the yellow shielded cable via an RCA jack I installed in the cover of the panel. The reed relay controls a small 10a cube relay, which in turn controls the contactor.
It was necessary to cascade relays like that because the 12v output is low current, and the reed relay's 1a contact couldn't handle the contactor's coil current directly. They're mounted on perf-board in a plastic box in the panel.
