Yeah, I know, the title sounds weird ... here is my setup and scenario (at home):
Guitar --> guitar cable --> Kemper Profiler (Toaster non-powered) --> Kemper Kabinet (active)
When playing in Performance mode I notice I get a "humming noise" audible from all higher gain profile. When touching the guitar cable (next to input jack) it disappears. So I assume this should be some kind of ground loop? I have tried different guitars and different guitar cables with same result.
What makes it weird is that when I switch to Browsing mode and selects the same Profile that caused the humming in Performance mode it's dead silent, no humming sound. I have not altered any settings of the profile in Performance mode. Seems to be the same regardless of which high-gain profile or Performance I select.
So, this seems strange to me. Is there any obvious setting I have missed in (like a global setting for Performance mode) that could possibly create this?
Thanks for any input in advance
