Hey all,
I seem to have a strange problem. My Kemper gives off a crackling sound (Link to hear it).
Yesterday I had this for the first time and at first I thought it was my power socket, so I tried another one and same thing. Then I changed out every single cable and same thing again. Then I turned off the Kemper for a long while and let it sit for an hour and came back to it: problem was fixed and no more crackling (or so I thought). I then played for 2-3 hours and it didn't come back.
Today I'm playing and at first no crackling sound ... after about an hour of playing the crackling returns. So I then unplug everything that's not the Kemper or my monitors. Still crackling sound ... I then downgrade to firmware 1.8.2 and crackling is gone. Played 15 min and no return of the crackling.
The first time that I had it (yesterday) I also:
- Tried another guitar
- Tried another profile
- Turned of everything in a profile: still audible crackling
Could this be a firmware problem or is it maybe the heat that's been going on in Belgium or ...? Fwiw: I've had my Kemper for about a full year.
