Plate Amp powered by battery? (alien.top)

Would it be possible to bypass the built in 120v power supply and power the amp using dc(battery). I assume it would be possible, but want to see if anyone else has done it. Using a Soundtown STPA-G500DSP

It really depends on the IC that is doing the work. I would bet money the IC is getting more than 12v from the power supply. You’d need to see what it’s getting by measuring it with a multimeter after you ID the pins for vcc and ground.
