Another Hum question

59 views, no responses? I called Classe today, once I learn French I'll get back with you on what I was told.

Sounds like a grounding problem (hopefully) rather than a caps problem (not so good) since it goes away in balanced mode.
As to what to do about it... check your power cord and the mains plug. Failing that, I think you're better off speaking to a technician.
Of course the french explanation will prime over all of what any of us have to say.

Xlr's fixed the hum :-)

Still sounds like a ground loop somewhere. I had the same problem when I had my Bryston. My brother in law had the same problem with his Classe cdp and Bryston and for him balanced cables resolved it. For me I had the B100 which didn't have balanced and lifting the ground from my power cord solved the hum until I switched to an Octave intergrated.

So am I okay just using xlr's, or do I need to fix the ground loop problem?

B_limo you should be fine. Only if you go back to rca will you need to address the ground loop.

Xti 16,
Thanks for the reply! I was also told that I could try getting a cheater adapter thst goes from a three prong to a two prong, but I've also heard not to do that, as it may be dangerous?

Jea 48,
I stumbled upon that very site lastnight. It was a little above my head, but I'll read it again and try to figure it out! Thanks.

A cheater plug is the same as lifting the ground. Normally it isn't a problem. Key word is normally. When I had the problem I could lift the ground on either the Bryston or my Meridian G08. I chose the G08 because is has the lowest current draw. That was something I was taught when I worked for TI with very large 'current' draw devices in computer systems (yeah the big 250 lb 25 mb disc drives). I even tried using a 2KVA isolation transformer with a balanced output. It cut the hum down a hair but also changed the hum to a buzz. I think the Xlr's is the best choice.
