Main Manual page 115/116 explains, how the PROFILER wattage protection works and who the KEMPER Power Kabinet should be used.
The PROFILER and 200 watts KEMPER Power
Kabinet are a perfect match in terms of signal level and headroom, and the
PROFILER’s soft-clipping algorithm is perfectly aligned with the Kabinet’s
power amp. The Wattage Meter on the Kemper Kone page is perfectly calibrated to
ensure the true values are always displayed. Furthermore, a wattage protection
algorithm will automatically turn down Monitor Volume when 200 watts are
exceeded, to protect the KEMPER Kone chassis from damage. For the perfect
match, and to fully benefit from these amenities when playing loud, it’s best
to leave the volume knob of your KEMPER Power Kabinet at maximum position and
use the PROFILER’s Monitor Output Volume to control the levels instead. If you
need to get even louder, you can still increase Power Amp Boost.
If you do not set the Kabinet’s volume knob to
maximum, the soft-clipping and the protection circuit might chime in too early,
and the Wattage Meter will show exaggerated values.
For relaxed “playing at home” levels however,
it is fine to use the Power Kabinet’s volume to your liking. Just be sure to
set the Monitor Output Volume of your PROFILER to a lower level, so that the
Wattage Meter doesn’t exceed 50 or 100 watts and to prevent the protection
circuit from kicking in.
If you lower the volume pot at the KEMPER Power Kabinet and then send a loud Aux In signal, the wattae protectionn might intervene and lower Monitor Output Volume.
