is there a way of muting the amp, putting it in standby mode and switch selecting the gain settings. The amp looks like the st' eval board. Is any of these options assessable or have they been hard wired?
I got this along with a pair of "HiVi B3N" (8ohm) and a "50K Audio Taper Stereo Pot" but I couldn't get it to work. I used the pot in the output side and eventually made it go stinky. Do I use pot on input side? Which and how to wire?
a pot for volume control would be placed on the input side. Controlling volume on the speaker level side would require an l pad. You will want to use a 50k stereo pot with each input channel wired to one of the joined pots.
