I recently purchased a used Crown Micro-Tech 1200 power amplifier. I seem to be having a volume issue, and I'm not sure why. I have read over the operation manual and found nothing that answers my question. My situation: I am running the Micro-Tech in Stereo, and I notice that Channel 2 is noticeably louder than Channel 1, with everything else being constant. All levels set the same on the preamp, using the same 8 ohm cabinet, and using the same cables to connect everything. I also made sure the gain levels were set correctly on the back of the 1200. When running Channel 1, the Channel 1 gain was turned all the way up while the Channel 2 gain was turned down all the way and vice versa. Any insight to this problem would be most helpful.
