I foresee no problems with turning all gear off and on using a master switch such as found on plug strips.

But what do I know, all I am is an Electronics Design Engineer and part time factory service technician for audio gear who turns his home studio on and off with one switch.

Matter of fact, my audio test bench, with all that expensive and calibrated test equipment on it, gets the same treatment daily. OFF in the evening and ON in the morning. At one place where I used to work, we turned the benches and equipment on and off daily using the circuit breakers in the panel. That way it was certain we didn't lock up and leave a possible fire to start in the night. Never hurt the sensitive audio and test equipment to do that.

And, when I worked at the old recording studio, did the same thing on a regular basis. Mic Preamps, main deck, submixers, power amps, tape transports, EQs and other goodies, all went on and off from the breaker box.

I wouldn't want to have to go around turning 24 channels of junk on and off separately. And you do not have to do that.
