Profiling An Amp; General Considerations - Kemper PROFILER Bedienungsanleitung

60 KEMPER PROFILER

Profiling an amp

Now we're getting to the fun stuff! Profiling your own amp, custom digital simulation, or favorite stomp
box is what sets the KemperPROFILER apart from every other digital amplifier out there. We've spent
years getting our profiling system to deliver the goods in terms of sound quality, playability, and ease of
use — all wrapped in a user-friendly interface. So while there's a lot of science and technology behind the
concept of profiling, you'll find that it's quite easy to actually do; this guide can show you the basics and
get you started right away.

General considerations

In order to make a profile, the original amplifier (which we will refer to as the "reference amp") has to be
connected to the PROFILER using the DIRECT OUTPUT and the RETURN INPUT on the back. The PRO-
FILER then sends various tones and signals into the reference amp — it will sound like warbles and static
at various pitches and intensities, in other words: not too musical! To get technical for a moment: these
dynamically-changing sounds allow the PROFILER to learn about the nonlinear behavior of the tube archi-
tecture and the dimensions of the passive components in the original amp. The PROFILER then listens to
how the reference amp reproduces these sounds and analyzes the results. These characteristics are then
recreated in the virtual signal flow of the PROFILER. Even the characteristics of the speaker cabinet and
microphones, including all the frequency buildups and cancellations, are detected and become a part of
the profile.
If that sounds a bit complicated, don't worry about it. The important thing to understand is that those
weird sounds are how the PROFILER determines the unique way that your reference amp changes the
sound of your guitar dynamically over time. With the information the PROFILER gets from those weird
sounds, it is able to create a digital profile of your reference amp.
You can also profile solid-state amps and modeling amps, although the results from profiling modeled
amps can sometimes be underwhelming. The reason for this is that some emulations try to mimic the typi-
cal tube sound using techniques that don't necessarily match the analog reality.
