to distort this sound if you want to! Inside the KPA, the "Preamp Definition" parameter has been set to the
center position, and can be modified at any time.
When it comes to crunch or high-gain sounds, the "Preamp Definition" value is automatically set to a posi-
tion that matches the reference amp. You can thus identify the virtual age of the reference amp and even
modify it on-the-fly.
When you create a new profile, "Power sagging" is set to zero by default. By increasing the amount of
power sagging, you can increase the dynamic range of your profile. This can be especially useful if you
have profiled a reference amp that had a distorted sound with a limited dynamic range.
✔ ✔
Tip: If you set "Power sagging" to the two O'clock position, and set "Preamp Definition" a little higher than
its original setting, you can make the profile of a great reference amplifier sound even better, and more dy-
namic, than the original!
The sound of the reference amp's equalizer circuitry becomes an intrinsic part of the profile, but the actual
settings of the equalizer knobs are not replicated. We assume that the sound of the reference amp is ex-
actly the tone that you want to achieve, hence the equalizer in the KPA is set to a neutral state, leaving you
free to tweak the sound to your taste.
To make another amp profile, just press the soft button labeled "Create New Profile". See? We told you it
was easy!
Profiling a rotary speaker cabinet
♦
The Kemper Profiling Amp already ships with some rotary speaker profiles and rigs which were captured
from the real thing, but if you have access to a different brand of rotary speaker, you can take your own
profiles, too.
To do this, first set up the rotary speaker as you would in a normal recording situation. Next, connect the
whole chain to the KPA, just as you would with a guitar amp. This time, however, two microphones should
be used to capture the cabinet - one for the bass rotor, and one for the tweeter horn.
Connect the microphones to a mixer, create a mono mix of the two, and send this to the KPA's RETURN
INPUT. The idea is for both microphones to be captured at the same time, resulting in a single profile.
Now, switch your Rotary speaker to high speed and start the profiling procedure. The profiling process will
ignore the rotation of the cabinet and only capture the typical sound character. The resulting profile will
