Power Amplifier; Power Amp Switch; Power Amp Booster - Kemper PROFILER Bedienungsanleitung

38 KEMPER PROFILER

Power Amplifier

The optional built-in power amplifier allows you to connect your PROFILER to 4, 8, and 16 Ohm guitar
cabinets, as well as passive linear cabinets. It is internally cabled to the Monitor Output, so you can use all
the features of the Monitor Output for the power amplifier as well. Please refer to the "Output" chapter of
this manual for more detailed information.
If you intend to drive a guitar speaker cabinet, remember to activate 'MonitorCabOff' in the Master/Output
menu. This way the cabinet simulation is bypassed, and the built-in power amplifier is fed directly by the
Monitor Output signal. At the same time, the Main Outputs feed the full studio sound to the main mixing
desk of the live venue.
You will find more settings for the power amplifier on the dedicated page of the Master/Output menu:

Power Amp Switch

Switches the power for the built-in power amp. There is no specific need to switch it off when not in use;
unlike a tube power amp, the built-in Class D amp is not in any danger when you have no speaker con-
nected. Still, you may want to switch it off to reduce energy consumption.

Power Amp Booster

As mentioned, the power amp is connected to the Monitor Output, which provides enough headroom to
support even the loud attacks and transients of clean guitars. However, this comfortable headroom will
naturally lower the signal volume for the power amp, so you might not achieve the desired loudness. Turn-
ing up the Power Amp Booster will increase the volume loudness by up to 12 dB, in addition to the other
volume controls in the signal flow, such as Monitor Volume or Rig Volume. Although this will bring the
signal closer to the headroom ceiling, this is no bad thing, as this happens in tube amps as well. Very loud
signals and transients will then be compressed by a nice, organic-sounding soft-clipping circuit.
