Noise on Dry (Direct) Output after being on a while, bug??

    Hi

    I have a KP Rack (unpowered) running latest SW version. 7.3.2.16239


    I have my recording setup wired as shown in the Kemper Outputs video. IE Main Left & R to mixing desk. I also have the Direct out going to separate channels on the desk to record the Dry signal.


    All works great for a while but after the unit has been on for a bit, anything for 10 mins to an hour, the Direct output is putting out very loud static sound, almost like white noise. It is definitely coming out the KP, nothing to do with desk, I can monitor it right back to the channel imputes. And when I power down and reboot the KP, all is well again for a while.


    Very worried if this is a hardware fault? Or is there a known issue/bug?


    Hope someone can help as it is currently useless as I have to keep rebooting to clear the noise.


    Thanks

    Mark
