Focusrite 18i20 2nd Gen SPDIF Coloring

    I tried various setting changes in the input/output section menus and googled the problem to no avail. It's running properly as far as I can tell except the tone is noticeably distorted and souns terrible when palm muting.

    Is this a common problem? Should I upgrade audio-interface? Thanks

    Sounds like either a clock sync issue or a digital clipping issue.


    With SPDIF, the devices on both ends must be clock synced. If your Kemper is from 2018 or later, it can slave to your soundcard's clock, otherwise the soundcard must be slaved to the Kempers clock.

    Make sure to check the SPDIF signal isn't clipping (hitting 0dB). I've noticed even some commercial profiles clipping with the SPDIF output level set at 0dB.
