frequency response of the cabinet. Also, the characteristic impedance curve of the speaker, including its
feedback to the power amp, is detected in fine detail.
In the next phase, slowly pulsating white noise is sent to the Reference amp. The volume of the white noise
is set to a level at which the reference amp starts to distort. This is how the PROFILER learns about the
dynamic distortion curve of the tubes in the reference amplifier. Using this information, the PROFILER is
able to recreate that curve with the highest possible accuracy. This is also true for transistor-based and
digitally-modeled distortions.
In the third step, the PROFILER sends a complex tonal texture that follows a mathematically-based set
of rules to the reference amp. This texture creates unique interference patterns that allow the PROFILER
to take a "fingerprint" of the DNA of the reference amp's particular sound. The distortion of the speaker,
along with the partial pattern of the loudspeaker diaphragm (also known as "cone breakup") are excited
by this tonal mixture. They complete the characteristic interference pattern that the PROFILER will repro-
duce faithfully, once the measurements have been taken.
User community and support resources
There is a very interactive PROFILER user community. Registered owners have full access to our forum,
where useful tips and tricks are shared by users - the advice extending way beyond the PROFILER to all
kinds of connected gear. The forum can be found here: www.kemperamps.com/forum.
Enjoy being part of the official user Rig Exchange, where a few thousand Rigs are already available. Com-
pare tons of amps and download Rigs of fellow users, upload your own creations to the Kemper cloud, and
share them with other registered users. Starting on our home page you can find the user Rig Exchange via
