Up2Stream Plate Amp 2.1. Low volume in one speaker

Hi,

I’m having a problem with my Boom box that I can’t find a solution to, and I hope someone can help me.

I’m using an Up2Stream Plate AMP to power the speakers. The issue is that the right stereo channel has a much lower volume than the left channel. I’ve tried switching the output cables on the amplifier board, and when I do, the left speaker then plays with lower volume, so it doesn’t seem to be a problem with the speaker or the crossover.

I can’t find anything in the APC that seems to affect this, and I have already done a factory reset of the amplifier, but it didn’t help. Has anyone experienced the same issue? Could the amplifier be damaged?
