Hey OUTLAW
Happy Holidays

Not to long ago i had a problem with my center channel fading out and when i touched the top of the amp it would Fix its Self Etc.

Response was (can't find any TICKET record here) Something about a Bad Cable Ground Or something like that Anyway
i replaced the cable and the fading problem seems tobe gone BUT i Have a Continuos BUZZ In the Center Channel Speaker Even when the Interconnects From the 990 to the 7500 are Removed
PLEASE HELP or Trade Even up for the 7700
^^^ HaHaHa ^^^

The best way to get Outlaw support feedback is the phone or the online support system . They're likely to see that sooner and get the information to the right person with those channels than here. In the meanwhile, check to see what cables might be near the speaker cable going to the center: if there's a power cord running in parallel for any distance, you could get a buzz similar to what you describe.

Thank You GONK
Happy Holidays
