I have a Proton D940 receiver and love the power amp section. Years ago the tuner stopped working and then the input selector went bad. I had Proton repair both (they say) way back when they were still in biz. perhaps 15 years ago. It didn't last a year if that. Anyway, there are pre outs and ins so I continue to use the poweramp section hooked up to my computer. Problem is some stuff is just so high level that I have to adjust windows' mixer down to barely any volume. Is there a way to wire the soundcard output directly to the D940 volume control and bypass its input selector switch?
