I didn't mention it before but there is another reason for not turning everything on at once. Every device has a high current surge at turn on, until the filter caps charge up. Individually it's not a concern, but with multiple devices it can be enough to pop the supply breaker. Since power amps have the highest current draw multiple power amps shouldn't be all powered up at the same time.

Great point, thanks Bill. I'm think with digital routing of signals, that it changes the possibilities for Pro Audio. I'd like to move the ADC all the way onboard the instrument / microphone, and the DAC to the power amp. Keeping the signal digital as long as possible. Since that requires a network, there's lot of opportunity, and spare bandwidth, to do a lot of signalling on the same network infrastructure. My initial question about 12V triggers was dumb, because that would be a separate network. But if I have to tie everything together with ethernet anyhow, then might as well wake up all the audio appliances on the network as needed. One less thing for the sound guy to remember. This is currently done with a lot of proprietary protocols / technologies, so I'm hoping someone has insight into the standards groups to see if there's something applicable. If I brew something up from scratch, then it's not helpful as I see it, yet another standard that isn't interoperable.
