Kemper-Reference amp mismatch & Return Level issue

  • Hello


    I have a rack profiler (the non powered version) for the last 5 years and so far it's been an extremely smooth ride!

    I have made a lot of profiles using a lot of different amps and cabs and never had an issue.

    To day I've tried to profile a high gain amp & I run on this problem :

    "Kemper Amp" slot sounds different to the "Reference Amp" , kinda boomy with a lack of presence ,and almost clipped if I had to describe it somehow.

    Also the return level changes drastically when the profiling procedure ends .Refining the profile makes it even worse.


    I've checked my cabling & I even minimized my setup to make it easier to troubleshoot but I had no luck ..


    I'm running the latest OS software ( both kemper & rig manager)


    Kemper is connected to my UAD apollo via spdif ,locked at 44.100


    I'm not sure,but I think that the issue has to do with the latest updates.


    Has anybody experienced something like that ?
