I have my system located in a room with track halogen lights. The lights are on a dimmer switch rated for 900 watts. I have an extremely noticeable buzz on my system at all times now only when the lights are on. I have tried isolating the power to the system on its own circuit breaker, changing the dimmer, but neither worked. I am running all power to the system through a Monster protector. Is there a line conditioner that will correct this? Is there a dimmer that will not give feedback? Does anyone have a solution? Any suggestions, would be appreciated. Thank you.
