Thanks to everyone that replied. I tried to disconnect the signal input from the back of the sub and waited 1 hour after turning
everything off. The green LED light stayed on. It was my understanding from talking to a Klipsch Rep. that the LED should either
go out or turn red when in stand by mode? I guess not? As long as it's not hurting anything or shortening the life of the sub, I
don't care if the LED is on or not. I just thought it would be drawing more power if it was on rather than in stand by mode even
if no signal was being sent? Thanks again for your responses.
