This last weekend I had a project idea pop into my head and I ordered these PCBs to use as part of it, but I'll have a 15V dual supply for power. I know I could just get away with using the positive rail for the Splitter and Mixer but for headroom purposes I'd like to use both.
@Robert looking at the Splitter schematic my plan is omit all the power components. Feed my ground, positive, and negative rails via the R101 and R102 resistor pads. The input pull-down resistor I'd put on the jack itself with the "real" ground. The output pull-downs likely are redundant and will be handled by the other boards they are connecting to. Any reason you can think of for why it might not work?
The Mixer looks like it would be the same as the mixer except there's no input "ground" pull-down, and the output pull-down (R11) could be handled similarly to the input of the Splitter.
