Kemper Stage - Aux HUM / BAD HISS

  • So I have plugged I do a lot of tracking and playing along to tracks as well. I have a Kemper Powered Head and a Kemper Stage. When I put a stereo split cable in return 1 and 2 of the Stage, and plug it into my computer there is a buzzing / hiss sound that is really, really annoying. When I do the exact same thing on my power head - there is dead silence. Is there a fix for this for the Kemper Stage, Kemper?
