Buzzing A500 (Behringer)

[kgveteran]

These little guys work well as far as headroom and sound.They handle surround duty with ease.......


.........But, the buzzing.Any other suggestions on how to stop it.I have a Lutron IR dimmer that is one source of buzzing.If I have to pull it and go back to a switch I'll do it, but i love my dimmer.

Help

have you tried cheater plugs?

have you tried using the 1/4" TRS input instead of the RCA? (an RCA to TRS adaptor will do)

I tryed the cheater plugs , but not the TRS. Thanx. I would really like to fix this rather than sell and begin looking for new amps. They do pack a punch.

The PS Audio Humbuster should cure the problem.

I've read that the RCA inputs on the A500s can indeed be noisy. I know at least one person who switched to the TRS and the noise was gone. :T

The TRS/RCA adapters, like magic.it might sound funny, but i think the buzz was getting into the mains too.it's all gone now.Thanx again
