Axiom Home Page Forums General Discussion Advice from Axiom Owners LF "burps" from my EP500

I'll take a guess and say you have a ground loop.My 350 did the same thing,the occasional "burp".Sometimes I would fall asleep on the couch with everything turned off and the 350 would go nuts,choppers leaving Saigon loud,and shake me awake.Install cable lately ???? just a thought.
