if you're not in rented property, reconnect away from light bulbs. even if you replace dimmer switches, you may still hear buzz from bulb coils and you may still hear pop when turning lights on.
Short of running new, dedicated 15 or 20 amp lines for audio, what can I do here?
My system is plugged into outlets that share lines with lights in the room. When I turn the lights on or off via their switches, which are dimmable, I hear noise through my speakers, and especially through my sub-woofer. Any correction other than dedicated lines for the audio?
