I feel like one channel is stronger than the other. If I play pink noise in mono, can I safely measure at the speaker terminals with a meter? Is this DC volts?
I guess it doesn't make much sense to measure in mono. You know it's amazing how many stinking problems I seem to have. I wanna just sit back and listen, but there is always something bugging me........grrrrrr.
Switch speaker cables at the amp end and see if the other channel is louder. Also playing your system in mono should tell if one side is louder. There are many things that can cause one channel to be or seem louder. You can measure the output from the speaker jacks but it is AC voltage.
Sure. It is AC, and will only be a few volts while the signal is quite loud, so you may not be able to observe any diference between channels. However, if you feed the identical signal into both amps you can accurately measure gain difference by putting your meter from one channel's hot terminal to the other channel's hot terminal. You will probably see a few millivolts. If you also measure the amp output (either channel) you can calculate the gain difference in dB.
