How To Profile An Amp Without A Cabinet [Direct Amp Profiles] - Kemper PROFILER Grundlagen Anleitung

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 dynamic,
than the original!
The sound of the reference amp's equalizer circuitry becomes an intrinsic part of the Profile, but the actual set-
tings of the equalizer knobs are not replicated. We assume that the sound of the reference amp is exactly the
tone that you want to achieve, hence the equalizer in the Profiler 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!

How to Profile an Amp without a Cabinet [Direct Amp Profiles]

So far, we have profiled combinations of amplifiers and cabinets. We call these "Studio Profiles". The purpose of a
Direct Amp Profile is to capture the sound of your tube-amp including its power-amp.
When this Profile is later run through the Profiler's internal class-D power-amp, or a separate solid-state power-
amp, into a guitar speaker, it will faithfully recreate the sound and feel of the original tube-amp. The Direct Amp
Profile can later be merged with the respective cabinet portion of a Studio Profile. Alternatively, Direct Amp
Profiles can be paired with arbitrary cabinet impulse-responses, imported by our CabMaker software. The result
is a complete Profile that can run a physical guitar-cabinet onstage for monitoring, and simultaneously feed the
virtual guitar-speaker sound to the main PA.
While it is relatively straightforward to capture Direct Preamp Profiles from line-level outputs of bass amps, or the
send outputs of preamps, capturing them from tube-amps that include the power tube section is a bit more chal-
lenging. It requires you to tap the sound where it is about to hit the speaker cabinet. This tap is the speaker out-
put, where high voltage and high wattage occur, meaning you will need a dedicated DI box for this purpose. This
specialized DI box is capable of scaling down the voltage to a line-level signal, suitable for the Profiler, on a XLR
output jack. The high-power signal is forwarded to the speaker cabinet through a different output jack.
