The one channel will operate properly with a load connected.
The other channel with send amp into protection with and/or without audio,once a load is connected.

OK. It's common to see 2.5v of DC on the outputs without a load on it. It doesn't generally indicate that there is a problem but if the amp is shutting down, there is likely a problem.

Do you have a scope?
