after going over several different circuits I find that grounding the input of op amps varies.w/ diode, w/resistor, w/cap, just ground it.
I attached a sch. of the EQ filter section as well as several different grounding methods
which is perfered??
also on the subject of grounds-should I keep all the audio grounds seperate from power grounds? something called star grounding?
note the amp for this circuit is totally seperate from the EQ circuit-a seperate componet.
yhe EQ circuit has its own power supply on board. Thinking maybe put on a pcb all its own
