Popping when source is switched or muted HUH????

I had the same issues with a BAT preamp. Bad output capacitor...not sure if this is what's happending to you. same symptoms.

I think it is simply a ground problem. I have had that several times with various pieces of equipment. Just get yourself a $2 adapter that has a 3 prong female on one end and a two prong male on the other. This will lift the ground. Put it on your source and I can bet your popping will disappear like magic!

You will probably get your Rotel back and still have the popping sound.

Hey Arther,
Boy when I saw your post my eyes got big and I rushed downstairs and hooked one on, no change, so I went a step further and hooked it up to one of the Stats thinking the speaker might be helped...wrong again, but thanks alot for the idea...anyone else got a idea? I think its gonna be going off to Rotel shortly.

This clicking or popping is probably a problem with the processor. Rotel has acknoledged some processors have this problem and I think has a fix (if it is software related or will replace or fix the unit If it is a chip problem. Maybe? They had problems with QC and has resorted just recently to playing every unit for like 72 hours after importing them and sticking a green sticker on the BOX to let dealers know its been tested. At least this is what I read somewhere.

Thanks guys for all your input, a fellow Goner' is lending me his pre while my Rotel is in service...thanks again for all your help!
