Try taking the Anthem completely out of the system. They are notorious for ground loop problems.
Transformer hum?
I have four different items in my system that use
transformers. Levinson 436 monoblocks, a Balanced
Power Technologies BP-3.5 AC Conditioner, an Anthem MCA-50 multichannel amplifier, and a
Monitor Audio FB210 Subwoofer. All of them are
emitting a low level hum except one of the Levinson
Monos. When I plug anything into the AC conditioner,
the hum gets a tiny bit louder. In the evening, with no music playing, I can hear the humming from my listening position. With music playing, the system sounds fantastic, but I've got to think it would sound better if I could get rid of this hum. It is driving me batty.
What have I got and how do I fix it?
