LEDs are putting static on my stereo? Answered

i wired a outlet so I could plug in a strip of LED lights that are able to run in different modes (flash, fade, different colors, etc) When I turn the LED lights on, the stereo, that is plugged into a different circut, has static that goes with the tempo of the lights. When I turn the lights off there is no static. What gives?

Here is what I got.

I used them in another part of the basement and they work good with no problem. i also checked the outlets with the 3 light tester and it says it is wired correctly.

The LEDs are being switched by high frequency signals, which are interfering with your stereo.

You need to put a bit of filtering on the cables to the LEDs

+1... Also, if they have a ground, wouldn't putting a ground lift in help as well?

Yes, maybe.

Also try a mains filter, but I doubt this is mains conducted.

Right. One thing I run into a lot is people plug their laptop with a ground into the same circuit as a soundboard. (Now first of all the soundboard and amps should both be on their own circuit.) I end up having to re-ground the laptop to something else or another circuit so that the grounds aren't interfering with each other. :(

The question should be,  is it radiated noise, conducted noise or both ??
