But on stereo out you don't have Kone technology and imprints, right?
Looks like you can, from the manual
• Use two cabinets equipped with KEMPER Kones as a mini PA, maybe for a spontaneous party. Feed your music into the Aux Input in stereo, as classic PROFILER models activate Monitor Stereo, use a stereo power amp into the cabinets. Only the guitar-speaker-like dispersion will make your cabinets sound different to a regular PA.
• 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.
