How Can I Eliminate Humming Sound?

[captnkarl]

I had the same problem and the answer I got was "get a 3prong to 2 prong thingy"...That worked great and have used it since. If you unplug your power supply to the laptop, that will eliminate it also (battery won't last for a whole show). I doubt that it is the club because I had it at every club and in my house and I know that everything is grounded right in the house because I wired it myself. Dell told me that unless lightning strikes the club I will be fine running the way I do now.
