I assume, that my Kemper is suddenly broken/malfunctioning. Just from one day to other it is not working properly, without changing anything.
1/ Symptoms:
- Display is flickering in red when shutting off the Kemper. This is lasting for quite a while. Even if I deplug the power cord it is still flickering for about 10-15 sec.
- The sound is awful from one day to the other. Sounds like out-of-phase, distorted, with echo, just very bad.
- Any reset and firmware update didn't help.
- No changes, when using the Kemper stand alone with only guitar and headphones plugged in.
2/ Setup:
- Kemper (black)
- KPA -> main outs (l/r) -> focusrite saffire pro 10 -> MacBook Pro via firewire -> Logic Pro 8
- Firmware: was 1.5.2.7, updated to 1.5.4 now.
- The setup worked fine for months, without any problems
3/ What I have done so far:
- Reset the Kemper as discribed in the wiKPA (tried about 5 times now)
- Deplug everything and replug only the Kemper
- Updated to newest firmware (1.5.4)
4/ Really, you haven't changed anything?
- Well, the only thing I did, is plugging in a FV500H expression pedal to "Pedal 1" with a balanced cable. But I did this already the day before, and there everything worked fine.
Any advice / hint is very much appreciated. I think I won't survive christmas break without my Kemper. Please help!
Cheers,
Knut
