The Built-In Power Amplifier - Kemper Profiler Main Manual

captured in the PROFILE. In regular Studio PROFILEs, the interaction is simulated. Only a solid-state amp can play
back your PROFILE in an authentic way, and imprint the original impedance behavior to your speaker, without
adding additional, unpredictable interactions and the colorations of another tube power amp.

The Built-in Power Amplifier

The optional built-in power amplifier allows you to connect your PowerHead or PowerRack to 4, 8, and 16-ohm guitar
cabinets, as well as unpowered full-range cabinets. It is cabled to the MONITOR OUTPUT internally, so all features
of the MONITOR OUTPUT are applied to the internal power amplifier as well. Please refer to the
OUTPUT chapter of this manual for more detailed information.

Power Amp Switch
"Power Amp On" activates 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 connected. Nevertheless,
you may want to switch it off to reduce energy consumption.

Power Amp Booster
As mentioned, the power amp is internally 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. Turning up the "Power
Amp Boost" 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". The "Power Amp Boost" has no further impact to the sound or
dynamics of the power amp. When the power amp is switched off, the "Power Amp Boost" is deactivated, thus
returning the full signal headroom to the MONITOR OUTPUT.
