Kemper Profiling Amplifier Rack BK


19" Guitar Preamp

Since the advent of modelling technology in the guitar amplifier world, guitarists have been able to access a variety of sounds and effects with relatively little effort.

But what if you want to take your own favorite sounds instead of the manufacturer's sound specifications? Prior to the release of the Kemper Profiling Amp, there were not many alternatives: either, as before the digital revolution, they dragged their entire equipment from place to place, or tried to adapt the modelled sounds of the modelling amp as far as possible to their own desires.

Kemper breaks new ground here. Instead of using predefined emulation of different amplifier models, the Profiling Amp (Nomen est Omen) creates an exact image of the sound set on the amplifier together with the connected speaker and microphone. This combines all the personal favorite sounds in one device. In addition, the sound profile can be edited with various floor effect emulations, master effects, equalizer, and so on. A separate amp fleet is not a mandatory requirement, because the Profiling Amplifier is already equipped with a large number of classic amplifier profiles. In addition, a large Kemper community has now established itself in the world where sound profiles are exchanged over the Internet.

The new generation of guitar amplifiers!

For a long time now, many guitar amp manufacturers have been on a quest to pack the sound of the world’s most legendary amplifiers into a single unit – none of them with any real success until, in 2012, Kemper opened a new chapter in amp history with its Profiling Amplifier. Using the entirely new and unique “profiling” technology, the sound of any desired amplifier can be recorded with a microphone and then further edited and shaped in the Profiling Amplifier Rack. The Kemper’s high-performance electronics and high-quality DSP effects, extensive routing options, wide selection of cab and microphone models, and intuitive user interface – styled after that of a real guitar amplifier – let you revive these legendary sounds, enhance them with contemporary features, and store them permanently: An ingenious concept that has ushered in a new era in guitar amplification.

The best guitar amps of all time, emulated to perfection

The Kemper Profiling Amplifier Rack is a dream come true for guitarists, and the search for that perfect amplifier ends here. The profiling technology not only gives guitarists countless amp models at their fingertips – it also lets them directly record and preserve the sonic characteristics of any amplifier they want: In other words, the boundaries of flexibility have now been completely re-drawn. Innumerable other digital editing options, which include substituting different speaker or cabinet types for the one used in the original recording, adding high-quality effects, and a wide variety of internal and external connection and routing possibilities make the Kemper Profiling Amplifier Rack without a doubt one of the most flexible guitar amplifiers on the market.

An ultra-flexible powerhouse for tone-chasers with pro aspirations

The Kemper Profiling Amplifier Rack comes in a studio-friendly 19” format and is ready for whatever challenges are in store, so there can be no doubt that this is a thoroughly professional piece of equipment. Fans of old vintage treasures can now harness the sound and characteristics of the originals – which are usually ruinously expensive and often very rare – and shape these to suit their own tastes without having to spend a fortune getting their hands on the real thing first. This powerhouse amp will delight tone-chasers and sound nerds alike with its extensive range of features and win over recording musicians with its impressive connectivity, which allows it to replace numerous guitar amps in the studio and ultimately save everyone a large amount of time and effort when it comes to cabling and miking.

About Kemper Amps

German firm Kemper Amps, or rather its founder Christoph Kemper, is no stranger to the music industry. His very first product, the virtual-analogue Access Virus synthesizer, was far ahead of its time and brought the company both unexpected success and an impressive reputation within the music profession. Continuing the momentum of this success, the company then developed the “Profiler” technology, which allows an astonishingly realistic reproduction of the sound of a miked amplifier to be made and thus represents the dawn of a new era in digital amplifier simulation. This technology is currently available in different variants of the Kemper Profiler system: As a basic head, as a top with a powerful Class-D power amp integrated, as a rack-mountable unit, and even as a floorboard.

The Profiler is up for anything

Whether it’s right next to the mixing desk in your studio rack, running through a power amp and speaker cab as part of your backline on stage, or in your living room for some quiet practice, the Kemper Profiling Amplifier Rack’s outstanding flexibility means that the amp’s potential knows no limits other than those of the player’s imagination. The wide range of connection options include on-board digital interfaces, such as an S/PDIF input and output and two USB outputs, which make it easy to record the Profiling Amplifier Rack’s signal to a DAW with zero loss in the studio. The Kemper Profiling Amplifier Rack comes with presets of many of the best amplifiers of all time already installed, however, so your quest for the perfect tone can begin right away.

The ideal accessory: The Kemper Remote

The Kemper Profiler Remote is a floorboard that is compatible with every amp in the Profiling series and can be used to remotely control and enhance all of the Kemper’s key functions, making it the perfect addition to any setup. It features a built-in tuner, four connections for expression pedals, and a large display that provides a clear overview of the presets and effects that are currently selected. What is more, the remote can also be used to control the Profiling Amplifier’s looper function, and its “Morph” function is a highly practical feature that can be used to seamlessly crossfade between one or more parameters – making the transition from a dry crunch to a lead sound with delay as simple as pressing a footswitch, for example.

In the spotlight: Profiling

In fundamental terms, the Kemper Profiler is primarily a highly specialised measuring device which, by means of a complicated algorithm, is capable of precisely replicating the tonal characteristics of a signal chain. Generally, this chain first and foremost includes the amplifier that is to be emulated, the cabinet to which this is connected, and the microphone that is placed in front of it. This standard setup can additionally be expanded by adding pedals, which can also be profiled as part of the chain if desired. An „amp only“ profile can of course be created, however, by connecting the amplifier to a DI box instead of a conventional speaker cabinet. To determine the characteristics of the individual signal chain, the Kemper then sends various measurement signals through the amplifier that is connected, on the basis of which it then creates a so-called “profile” – which even professional musicians have difficulty in distinguishing from the original in terms of sound and dynamics. The user can subsequently customise this profile by fine-tuning a range of different parameters before naming and saving it. In this way, players can archive their entire amplifier collection virtually without restriction and take it with them to gigs and into the studio.

Kemper Profiling Amplifier Rack BK
Valeryy 10.11.2020
The device is amazing ! I bought it for my Studio .At first, I did not immediately understand the tricky settings . Using Rig Manager greatly simplifies the task . With the connection of the MIDI controller, too, not everything worked out at once, but this is rather a lack of personal experience. Overall, the device is great, the sound is great, but it took some time to fully understand .


Best piece of guitar equipment i've ever used!!
Ian141 07.11.2015
I've been a valve amp man for over 15 years and thought i'd never stray from my Mesas and Diezels, but as i've got older it's not as easy to 1) Carry all that around to gigs, rehearsals 2) Jam or record without waking or annoying my kids or the neighbours.

The Kemper seemed like the perfect solution, and so it is. The sound quality is outstanding, truely outstanding. Yes i may take you a while to find your way around it, but once you've got things dialed in the way you want you'll not hear any difference from the real thing to the Kemper. I've profiled and bought some great profiles of my favourite amps, and every one sounds incredible and if it doesn't try it with a different cab or pop some eq on it. The options are soooo vast.

The layout is fairly straight forward, and adding effects to profiles is soo easy. With independent buttons for each effect you choose. Want some delay? Tap it in with the tap tempo button then set your mix level and save. It's as easy as that. Having owned a Mesa Dual Rectifier and Diezel Herbert, the profiles you can get are soo close you'll think you are playing the real thing.

I got the non powered rack head, and its super light. Accompanied by a Thomann rack it's bomb proof and soo much lighter to carry to gigs and rehearsal.

This is the best piece of guitar equipment i've ever owned, and the pros that are dumping their big heads and cabs for a Kemper are testimony to this.

Don't think about it, do it, and buy it from Thomann...obviously.


Kemper is an excellent complement to boutique amps, and beats AxeFx2 for amps
Anthony3107 30.01.2014
For my cleaner, plainer amp sounds, I have only ever found/tweaked a few clean patches I really liked on my AxeFx2, and nothing that every felt/sounded much like my favourites: my Dc30 or Ceriatone BM (John Mayer Type Dumble clone)

However, Straight away, on day one with the Kemper, from the free shared KPA patch database online, I have patches that are close enough to these 2 for me to enjoy. Certainly at present, simpler cleaner patches with a lot of amp feel that I would often use are more plentiful on this KPA

I was not initially too impressed with the factory-supplied cleaner or metal/rock sounds on the KPA, and the FX are a bit fiddly from the control panel (although that is compared to the dedicated main controls - volume and EQ - still easier than the AF2). Having the dedicated Bass/mid/treble/presence is such a pleasant change, along with the input gain and volume controls

As I said, the sounds I was looking for were available on day 1 with the KPA (not from the KPA-stock rigs though). The Thomann USB stick had a lot of very good sounds, the free Lasse Lammert Signature Rig Pack is exceptionally good for rock and metal, and the KPA forum has quite a few good ones. I went to specialist profiling suppliers for more ones, you can find a few online

KPA is not as heavy or solid as the AF2. Who cares though, it lives in a rack
KPA has no fan - what a relief, the AxeFx2 fan is very noisy
KPA does not try to blow your speakers when you power off if you forget to mute it first - the AF2 does create a big pop
The AxeFx2 FX are way better (delays and reverbs, pitch, etc), the PC.Mac based AF2 editor is better than using the front panel, making routing etc easy on the AF2, in comparison, the KPA is very simple and inflexible
The KPA deals with different guitars & pickups better (using the clean sense control, and the always-enabled input gain knob etc)

Overall I feel much more like I am playing and hearing a guitar amp with the Kemper, it is perfect for recording. For more ambient and effect-driven sounds, the AxeFx2 would be better


Kemper Profiler Rack
Chris2807 24.01.2017
I came from an Axe FX II to this, for use in the studio..
I like to set up my parameters from the front panel, with no computer connected, and the Axe FX was pretty tiring in this respect..
The Kemper is much easier to set up from the front, very simple in fact, and the sounds are of excellent quality..
I found the parameter system a bit alien, not much like anything I've used before.. A bar traversing the screen which increases or diminishes according the the amount of effect.. The descriptions of the parameters too, are unusual in general.. There's nothing wrong with this, but I must admit that personally, I prefer a simple numbers system, and classic parameter descriptions, as per most other multieffects. I feel more at home..
Everything sounds great, but I would have liked a parallel routing option included, and I must admit that after loading the USB amps bundle I got from Thomann, I found that there was simply too much choice.. It's pretty tedious trolling through all those amps to try and find one that suits- some sound quite similar.. but if you don't mind that, there's a mountain of choice.
I loved the automatic volume compensation on the compressor, and particularly on the amp gain.. That saves a lot of messing about.. A great feature.. add as much gain as you like, but the volume level stays the same..
I didn't use the amp profiler, as the available sounds are good enough anyway, so I can't comment on that.. I imagine this would be perfect for someone who wants to sample their own amp sound, and have it at their fingertips in a lightweight box.
This is a great product, but I'm going to change it for the Helix, which wasn't yet available at the time that I bought the Kemper. This is mainly because the set up from the front panel is so easy, and the routing options permit more inventive algorithms.. This is important to me.. However, I can highly recommend the Kemper, it is excellent..
