Kemper stage latest update - High pitch crackle

  • Hello all, I have just updated my Kemper stage with the latest update and I can detect a high pitched crackle going on in all of my profiles no matter how clean or distorted they are. Any ideas how to fix that? Thanks in advance.

  • Are you using spdif?

  • Yes, spdif sync to the audio interface at 44.1kHz

    Yeah that seems to break every once in a while. Of course the short term solution is to use analog.

    Perhaps I am having the same problem? It has nothing to do with spdif as the other poster referenced. After updating my Stage last night all of the profiles are fizzy in addition to sounding like all of the bass and mids are shut off. I have not had the time yet to roll back and see if this issue persists.

    I think that you should do a factory reset of the Stage

  • Please check out OS 8.6.6 which should solve S/PDIF glitches with some sampling rates on PROFILER Stage models as well as some other issues.
