Hi all!
yesterday while I was playing my sweet KPA (lunchbox green, no PA on board, bought from Davide - guitarnet70 here on the forum), the KPA emitted through the speaker a medium high pitched whistle (and no more sound from the guitar).
I had to reboot the unit and after that every input on the KPA does not work, and DSP error was lit in the top right of the display. If I pressed the key over dsp error, the KPA says "snapshot saved", so I guess it's only a notification.
The tuner (and all of the KPA) does not receive any input (front, alternative, return input)...and of course I have no output, too. Things I tried:
1) booting with system pressed on
2) updating firmware to latest (DSP error it's not showed anymore)
3) front and alternative input with different cables and guitars
4) resetting midi pedal values
5) checking spdif option and set / unset that
I did a search on the forum so I checked the most common stuff (yes, my input cable is in the right hole, unfortunately , tried profiler mode, spdif, manually setting midi volume pedal value )
I hope to be wrong, if there are other tests I can try to restore my inputs please let me know, but I think my KPA needs tech assistance
PS I sent an email to the support team few minutes ago.
