Help Troubleshoot - Left Ch. Louder than Right Ch.


I need your collective troubleshooting assistance.

I just put together a new system (comprised of used gear, of course) and hooked it all up last night.

Unfortunately, the left channel is considerably louder than the right. Or - it could be that the right is much QUIETER than the left. Not to be facetious, but in actuality, the left channel seems more "appropriate" all things considered.

The amp is an Antique Sound Labs AQ-1002 (50wpc) and the preamp is a Counterpoint SA-1000. Unfortunately, I don't have any additional components to swap out and determine which piece is the culprit. Can you guys think of any other techniques that might help determine what's causing the problem?

Also, if the amp is not biased properly, could that cause one channel to play louder (or quieter) than the other? There are no Gain controls on the amp that I can see.

I need to figure out what's wrong so that I can either fix it, or seek recourse from the seller before too much time has elapsed.

Thanks guys!

Your source equipment could also be the cause. Also, the loudspeaker.(Depends on how close of a tolerance the manufacturer used w/ the drivers.)
Try swapping the left and right input cables on the back of your amp ( power it down first)
Then listen and see if the louder sound is on the same speaker or if it moved.

If the other channel is now louder the problem is in your preamp or before. IF the same channel is louder it's in the amp or speaker

Jeff, you're a genius!

I'll give that a try this evening and report back tomorrow.

If it turns out to be the amp...Does anyone have an idea of what might cause such a thing? Could it be as simple as the bias?

Thanks!
