Power Amplifier
The optional built-in power amplifier allows you to connect your KEMPER PROFILER to all kinds of 8 or 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 our "CabDriver" algorithm, by setting
"MonitorCabOff" in the Master/Output menu. CabDriver bypasses the cabinet simulation for the Monitor
Output, while the Main Outputs feed the full studio sound to the main mixing desk of the live venue. The
Monitor Output is still available and will carry the same signal that is fed to the power amp.
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 loud attacks and transients of clean guitars. However, this comfortable headroom will natu-
rally lower the signal volume for the power amp, so you might not achieve the desired loudness. Turning
up the Power Amp Booster will increase the loudness by up to 12 dB. Although this will shrink the head-
room, 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.
