Loud Buzz through Speakers when Connecting USB to iMac

    I've had my Profiler Stage connected to my computer since I got it. This morning there is a loud buzz that comes through the external cabs I'm using when the cable is connected. It goes away when it is unplugged. This has never happened before today. Software is up to date. Ideas?

    Use the same wall outlet for all the equipment that is connected (computer, Profiler, powered cabs/speakers, ...). The buzz might be caused by a ground loop. If all equipment is hooked up to the same wall outlet and the buzz isn't gone yet:


    1. Something has died and caused this to suddenly happen.

    2. Try the Ground Lifts on your stage (OUTPUT menu page 9/9). Just make sure you never lift all at the same time!!!
