from the manual:
• A signal on the Aux Input fed to the MONITOR OUTPUT by using the “Aux In >Monitor” control will be processed by
the KEMPER Kone intelligence as well. It will always be processed in full-range mode, even if you play your Rigs in
Speaker Imprint mode (Monitor Cab Off active).
• The ultimate KEMPER Kone setup: Play guitar along to the stereo input using the speaker imprints, while the music
plays full-range, through the same cabinets.
