My Sub 37 just quit making sound this morning.
Updated the firmware. Nothing
Re initialized. Nothing.
New Cable. Nothing.
Yes it is plugged into a regulated power source with surge protection. It just quit 
Headphones and main output gone. So now I have a really pretty 1500 dollar light show. Just wanted to let everyone know. I’ve heard of one other person with this problem. Not sure what Moog did. I hope they fix mine.
