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?http://cloud.tapatalk.com/s/5a485924ba3d6/yamaha_m1516.pdf

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.
SIGSEGV is inevitable if you try to talk more than you know. If I say gibberish, keep in mind that my license plate is SIGSEGV.
