I have a Paradigm PS-1200. I had powered everything down and was ready to go to bed. Needed something from the kitchen, so went in and flicked on the light switch (florescent light). Kitchen and living room are one big open room. My sub was still on, due to it's auto on/off feature. THe receiver was off. When I turned on the light, I got some feedback from the sub. Sort of like it was playing one single note every time I turned the light on and off. I never noticed this before. What's causing this to happen, and will this damage my sub?
