I will have to do some more troubleshooting today, but yesterday I ran into an issue with a huge amount buzzing coming from my Kemper. It started right in the middle of a practice. I swapped every cable connected anywhere, swapped out the wireless unit for a cable and swapped it. I tried going XLR and 1/4. I tried multiple guitars. It occurred on any patch with maybe three or more gain dots, so it wasn't just a high gain patch issue. Only thing I didn't do was go straight to the PA. We were practicing in the basement, since it was 89 out and our usual practice space doesn't have AC.
I'm going to troubleshoot it some more, today, but I thought I remembered doing some type of a "Kemper reset", a while back, when I was having a different problem. This reset a bunch of stuff back to factory, but kept my profiles and performances.
I saw this in the manual:
In case any inputs or outputs don’t operate as you would expect, or you experience any other unpredicted behavior,
the soft button “Init Globals” in System Settings will reset most global parameters in System Settings and Output
Section as well as returning all locks to their default state.
but I thought there was something I had to hold down while I powered the Kemper on to reset things, while keeping my profiles. Am I imagining this, or is there another type of reset that does what I am looking for? Thanks.
