plotting a power amp build and want to put an EQ and volume control out front. basically a take on a SD powerstage. The power amp module has a built in PSU and an auxilery bipolar 12v output. I've heard people say that running an op amp circuit off of ±V instead of +V/VREF is an easy mod, but I can't seem to google the right words to find an example.
can anyone provide/point me to a schematic for such a thing? thanks
