I had attenuated my left speaker with two pushes of the left balance control button (2db correction).Reorienting my speakers, I no longer need the attenuation. I've tried several pushes on the right channel button, but the green light remains ON for the left channel. (Pushing the left channel button doesn't help!)
I've tried unplugging the unit and letting it sit for some time. This doesn't help.
How do I get back to the factory-set balance?
