Strange behaviour with output volume

  • The Profiler Model referred to in this thread is ...
    ☑️ Profiler Player

    I have plugged my player in and tunred up the monitor out volume to maximum (0 db).

    When I then play, the volume reduces automatically down...how much down varies on the rig used so looks like some kind of automatic balancing of output volume. It only moves down and never up.

    Im not aware of this behaviour at all, is this normal?

    My set up is a player, monitor out into a Harley Benton power amp into a kabinet...
