Re: using Paia power supply to power diy modules
It depends what kind of activity there is with the module. If it is something like a preamp or mixer and only operating on audio, use the cleaner SG to the module. If it is generating clocking or pulses which could be a source of tones or clicks, use G. 9700 series modules use these in this way, with each of the two wires going to separate terminals on the module. It would work to use either because they go back to one point on the power supply, but to keep possible interaction at a minimum, they're on separate wires for the run.
