I hooked my new Audiogram 6 to my iMac to use with Garageband, but I am getting an annoying ground loop noise.

 

I have my Korg Kronos connected to the Audiogram 6, which is connected to the USB port of the iMac.  I have a pair of Yamaha SC50 speakers connected to the output of the Audiogram 6.

 

When I connect the Kronos directly to the Audiogram 6, there is no ground loop noise.

 

If I connect my headphones to the "PHONES" output of the Audiogram 6, there is no ground loop noise.

 

Any suggestions?

 

Thanks!
