KPA Recovery Hints

The KPA may not react or boot in some rare cases. Here is a summary of my findings to get him back to life.

KPA does not react anymore Switch the main knob to off wait a few seconds switch on again If the above did not help: Switch the main knob to off wait a few seconds unplug the KPA wait 15 minutes plug switch on again

KPA does not start anymore There are different reasons why the KPA may not start anymore. The most common thing is a corrupt rig e.g. after downloading a corrupt file To reset the last used (corrupt) rig do like this: Switch the main knob to off wait a few seconds hold the 'Rig' key while still holding the 'Rig' key - switch KPA to tuner If the above did not help: There are other keys to reset other parts of the KPA memory. To reset the (corrupt) Midi settings do like this: Switch the main knob to off wait a few seconds hold the 'Quick' key while still holding the 'Quick' key - switch KPA to tuner To reset the (corrupt) System settings do like this: (Note: All your system settings will be erased - but not your rigs) Switch the main knob to off wait a few seconds hold the 'System' key while still holding the 'System' key - switch KPA to tuner If the three options above did not help your KPA back to live, you may have a completly corrupted rig library or even the firmware may be corruped Check the sections below to recover from this.

Install or reinstall the firmware Switch the main knob to off Download the latest KPA firmware Get an empty fat32 formated USB stick Copy the unziped firmware file 'kaos.bin' to the root folder of the USB stick Plug the USB stick into the KPA Press and hold both '<' and '>' keys while still holding both keys - switch KPA to tuner Something like 'booting and installing' will be displayed Wait until the firmware is reinstalled

Erase the internal flash memory Note: Section removed There is no need for this anymore - it was only for older firmware versions. If you think you should do it - please contact Kemper support.

Check the KPA hardware Note: Make a backup of your rigs before you do all this. Switch the main knob to off Hold the left/top soft-key above the LCD while still holding this key - switch KPA to tuner Maintenance Module will be started In the 'Maintenance' menu goto 'Test' A lot can be tested (buttons, knobs, led, memory, ...)
