If the noise is actually hum, then you'd probably have the same hum no matter what kind of bulbs you had. Treat the problem like an ordinary grounding problem and you'll probably solve it. > I tried setting the FD manually to filter the offending frequency, but > that is not working. What's the offending frequency?

No such thing happens with (non dimmed) incandescents. > Treat the problem like an ordinary grounding problem and you'll probably > solve it. ** No you won't !!!! >> I tried setting the FD manually to filter the offending frequency, but >> that is not working. > > What's the offending frequency? ** 120Hz plus all odd numbered harmonics - much like dimmer buzz. .....

Unplug stuff starting from the inputs until the noise goes away... You could also try turning off lights as well... As someone said, noise in sound systems from fluorescent is not normal... so it's either some cheap thing connected to it, or where you are there is a lighting equipment/wiring problem. The only time I ever had a noise problem like that in a sound system was at the local legion hall, where some yahoo ran 200' of cheap mic cable all around the walls, tied to the electrical conduit... un-balanced cheap coax... and connected it to a Radio Shack mixer!

If someone sneezed near a mic and that sneeze was heard through the peakers - he would immediately come here asking how to fix a sound system with a cold. .... Phil
