Hum/Buzz

I'm having a hard time removing a hum/buzz from a PA system. There's a buzz from all speakers with only the amps turned on and the inputs shorted. I've got Jensen isolation transformers on the inputs to eliminate ground loops, and a Furman PL8 II for power conditioning.

The noise is not vlolume dependent. Moving power wires away from the speaker wires has no effect.

Any ideas? Would it be worth upgrading to the Furman plus series?
