Main outputs, suddenly no sound

  • Here's an odd one. I was playing away for about 30 minutes and then suddenly no sound output from the main stereo outs. The unit was fully functional otherwise (no freeze).


    I rebooted and all was good again, but a bit worrying, especially troublesome if it happens during a gig !

  • I had this problem with the original fw, have you updated yours?

    Yes, I am now on version 7012 that Kemper sent to me by email just today. Also I can force this bug to happen if I turn the character of the cab back and forth a few times....very consistent bug. I have reported to them.

  • Same problem today with last firmware while tweaking the cab settings, had to turn off the kpa to get the sound back

  • Please guys, would you be so kind to submit this problem to support using the contact form on the webpage? ...I mean all of you.
    This looks to be a confirmed bug.

  • yepp, I've had that since day one...waiting for the kemperpeople to solve it. only positive thing is that it has never happened while playing :S

    If you don't edit the cab it does not happen, something wrong in those settings...

  • I have the same problem.The guys from Kemper have been able to replicate the problem and are now looking into it. I've received an email about that.


    --Nothing scientific from this side sowever what I've noticed is that the issue occurs whenever you select a Rig which has been profiled directly from the DI of the amp (i.e. no cab miking involved) and then you try to tweak its cab parameters. That's what I think it's happening to me at least...

  • NO SOUND when making adjustments to cabs!!! :thumbdown:
    I'm on 7034 beta! Reported to support!
    It's time for a new fixed firmware!!!

  • And then? Don't edit Cabinet-Parameter forever??? If you change the Low & High-Shift & Character parameter, the KPA crashed with NO SOUND!!!
    I reported this bug from firmware 6985 - 7034!!!
    We need a fixed firmware!!!
