Any ideas why my amp buzz's......

Any ideas why my amp buzz's when I hook my tv up to my Integrated amplifier? I use two different pair of speakers: Triangle Zerius and Quad 12L Pro Actives. It only buzzes when the Quads are hooked up not with the Triangles. The Quads have 40/60 watt amplifiers built in and they are hooked via pre out on my integrated using analysis-plus interconnects right into the back of the Quads. Any comments or suggestions would be a big help till I buy a pre amp for the Quads.

Thanks,
Tom

Ground loops via CATV co-ax are very common. For a cheap fix, get a ground isolation transformer for the co-ax line from Rat Shack. For a more expensive fix, a Mondial MAGIC. Fix # costs less than $10, fix #2 costs about $100.

Ground issue. Try lifting the ground on the quads or tv.

Programmergeek has the first solution you should try. By "lifting" you should put a cheater plug on the amp and see if it fixes the problem. If not, try the cheater plug elsewhere in the system, i.e., the Quads, TV, etc. I would try it first on the amp, though...let us know how you make out.
