    Humming sound from Monitors

    I have a Behringer XenyX Qx1202 USB mixer plugged in via USB into my computer and I have my Studio 50 USB monitors plug into the mixer via analog plugs and I keep getting a humming sound when I power the speakers on.

    But when I unplug the usb cable that runs to my USB mixer the humming stops but now my mixer is not connected to my computer so I cant hear my Studio 50USB monitors.

    Computers are known to do this. Is all of your gear connected to a grounded mains power outlet?

    Here in Europe we can turn the power connector so that we swap the live and neutral pins. Try that if possible.
