I have a couple channels from a Yamaha m1516 mixing console and I would like to power them up, do some signal tracing, and see how something like this works.
The board is supplied by +/-25V, +10V(led indication), and +48V(phantom power). I would be powering it with a dual bench PSU.
Is it generally safe to power the board solely with +/-25V to test the signal path?
