I picked up a Evans rack mount system with a Stewart PR-500 power amp in it.I can only get hum out of one speaker.Other side works fine.First time owning one of these.Any help on the wiring to the power amp would helpwould be greatly appreciated. Mike

Are you running only one cord into the left/mono input? A picture of your wiring might help here... can you swap the cord to the other input and get sound out of the other speaker(with sw in stereo mode)?
