Powering part (or most) of a circuit?
« on: December 31, 2017, 02:38:41 pm »
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?

I see no reason why this board would not work without 10V and 48V. All local rails (23V and 16V) are generated from 25V on board.
