Profiler Stage - heavy humm/noise when i connect Send1 to the amplifier input

  • Hey Everybody,


    I'm new to profiling and just did my first profiles of my sons Engl Fireball 25.

    It works and I've got good results so far BUT:

    As soon as I connect the instrument cable from Send1 to the amps input it makes a bad noise.


    The Kemper doesent profile that, so I'm happy.

    The profiles turned out quite nice - but its mean working with that noise on the studio speakers the whole time.


    I checked it with three different high quality cables - same result


    So, what am I doing wrong? Using a TRS wouldn't make any sense for the amps input isn't trs.

    Is it normal, to have a lot of humm and noise?


    By the way, Kemper tells me it detects a noise gate, (wich is very funny with that noise) even though the amps noise gate is turned off, definitly.


    Any sugestions. Thank you!
