doggiehowser, on the lower right rear of the F113, next to where the power cord plugs in, there is a switch that allows you to choose "grounded" or "isolated." Does the sub still hum when this is set to isolated?

I noticed mine had a slight hum/buzz when I plugged in power but it buzzed even without any RCA/XLR connection plugged in. And this is with the grounding set for RCA.
No fan in JL Subs.

Yes. I tried both grounding settings. Still the same.

doggiehowser, I hate to say it, but since "isolated" lifts the ground and you have a high pitched buzz rather than a hum, it sounds like an amp problem.

I'm thinking the issue I had was with the amp---I was sleeping in a dead quiet room at 4am and then I thought one of our smoke alarms was going off--woke me from a dead sleep--it was not a subtle hum--it was a moderately loud buzz--took me a minute to discover it was from one of my F113s--mine was only a few months old--had never had any problem--the unit was switched on and receiving NO signal at the time the buzz began. I disconnected the XLR cables--cutoff the unit--turned it back on--same loud buzz. I wish I had received a repair diagnostic but they did not send one. My units are on dedicated 20amp circuits.

Mine isn't high pitched. Just a low hum or buzz.

doggiehowser, please forgive this question, but is there any chance the ARO test is running or the demo mode is on?

Also, sorry about not being attentive enough and thinking it was a high pitched noise.

It's my fault for not being clear when I borrowed the thread I was still a newbie and couldn't create a new thread.

It's a noticeable when there's nothing running but not really an issue when I am watching a movie. I am powering it off a PurePower. Maybe that's causing the issue. I didn't have a long enough power cord to try it direct to the mains to see if that could fix the problem

Failing that, I am going to get an electrician to run a direct line from the circuit breaker for my hifi gear. Hope that works.
