62 KEMPER PROFILER
PROFILER. To ensure that you are only hearing your reference amplifier through the PROFILER, it's a good
idea to place the speaker cabinet of the reference amp in a different room (in other words, somewhere you
won't hear it) and away from the monitor system you are using for the PROFILER. Keep in mind that this
will not change the result of the profiling process in any way, but will make A/B comparisons between the
reference amp and the PROFILER much easier.
If you want to make profiles of computer-based amp simulations, but without using any kind of external
mixer for monitoring purposes, you need to be careful not to create a feedback loop. One easy way to
avoid potential feedback loops is by using only headphones to monitor the output of the PROFILER while
profiling. You can also make appropriate settings in your DAW to prevent the output signal of the PRO-
FILER from being routed back into the PROFILER.
Considerations regarding noise and hum
♦
If you're profiling a very high-gain sound, you'll probably hear a certain amount of noise from your guitar
amp. This is the well-known "high-gain hiss" and nothing unusual. However, if you detect hum, or other
noisy artifacts, from your reference amp then you probably have a ground loop. Press the GROUND LIFT
switch on the back of the PROFILER for both the MAIN OUTPUTS and the RETURN INPUT. If that does not
solve the problem, try different combinations using the other GROUND LIFT switches. It is important that
at least one of the GROUND LIFT switches is not pressed to make sure that the PROFILER has at least one
ground connection.
✔ ✔
Remember that hum and noise is undesirable and might have a negative influence on the profiling process.
Often, the best results are achieved by pressing the GROUND LIFT buttons for all outputs except for the
DIRECT OUT.
Other considerations
♦
✔ ✔
Make sure that you are hearing the previously-selected rig in the PROFILER when you set the A/B com-
parison to "Kemper amp", and the to "Reference Amp" when you switch to reference amp. If you don't, re-
connect your reference amp to the PROFILER.
✔ ✔
Playing back profiles over the MONITOR OUT using a regular guitar cabinet is one of the main features of
the PROFILER, but it is not recommend to use a guitar cabinet as a reference monitor for a profiling ses-
