Hi
I'm hoping someone here can help me out with a problem. When I connect my Boss GT-100 to my iMac and connect my Presonus Sceptre 6 monitors I am getting a lot of scratchy static. It's not the usb cables as I've tried a few different cables. It's not the iMac cause when I connect a Duet 2 interface there's no static. It happens as soon as I connect the usb cable to the GT-100. I don't even have to turn the GT-001 on and it happens.
Anyone got any ideas on how I can fix this.
Cheers
Michael

appogee Duet is USB Powered - therfore its immune to  USB Ground Loop noise from an external Audio interface power supply

Since the GT-100 must be powered from AC Mains supply - you can experience USB Ground Loop noise
