I have a Capcom Impress. I get clean, normal sound from my Tetris board. It's mono.
I'd like to connect a line level source to the stereo inputs on the Impress' power amp. When I do, there is a 60 hertz hum, and if the signal gets too high, it clips. I notice that the screen brightness pulses when the clipping starts. The hum (when there is no clipping) is constant even with the monitor off.
I don't have a stereo game board to connect to troubleshoot it. Are the stereo inputs on the power amp (not) line level?
What else might it be?
