Have you try with different speakers? Mixer?

[VanGogo]

Unplug your laptop power cord and see if it stops. If it does you have ground loop hum.

Connected it to new mixer still same thing loop Hum ???

Did you check by unplugging the laptop?

Using the balanced TRS connections might help. Or you can get a hum eliminator like the Hum-x or other like these http://www.amazon.com/s/?ie=UTF8&key...l_30i6u09a7f_b
