    Audible high-pitched noise on USB output of mixer

    My Q1002USB desk is connected to my Windows 10 PC via the USB port. There is an audible noise, considerably worse than the connection of my Steinberg USB audio interface. Is this noise to be expected given the low cost of this mixer?

    Sometimes you can get a ground loop between the pc and usb device. This happens mostly with laptops.

    Are your outlets properly grounded?
