Hi, I have a GM4200 which will not raise or lower the input gain when the gain pot is adjusted.
I have cleaned the gain pot, checked for dry solder joints and no change.
I tested the amp with both phono and din input, interestingly when I use a din input the amp plays louder but the audio is distorted unless I turn the source volume down.
Using din input has no affect on the gain pot either?
