Kemper Power Rack Input loss

  • I’ve recently bought another kemper powered rack


    The input sometimes looses volume by around half and fixes immediately when I unplug and re plug into the front guitar input- why does this happen?? easy input fix?


    Kemper want me to send it to them to get a quote to repair but it could take a while to get back- I don’t have a backup I need it to gig/ record etc!:/
