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 PROFILER, 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 PROFILER's RE-
TURN INPUT. The idea is for both microphones to be captured at the same time, resulting in a single pro-
file. 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 probably sound weird and uninspiring on its own, but when you engage the "Rotary speaker" stomp in
the MOD module, you'll hear the rich and animated sound of your original rotary cabinet.
✔ ✔
Tip: Although the profile is captured in mono, you can use the "Rotary speaker" stomp in the MOD or X
slot to recreate the typical stereo movement of the signal. The Rotary speaker effect will automatically
separate the bass rotor from the tweeter horn.
Under the hood
In case you enjoy reading about technical details, below is a description of what the PROFILER is doing
during the profiling process:
During the first phase, you will hear white noise with a rising amplitude. The PROFILER is now collecting
data about the frequency response of the reference amp. The frequency response will change dramatically
as the gain increases. This is how the PROFILER learns about the circuitry of the reference amp and the
