Modern version of a semi-modular classic

The ARP 2600 was an extremely popular synthesizer when it hit the market in the 1970s and is today considered a true classic. With its semi-modular structure, duophonic mode, separate keyboard and of course its wealth of sonic possibilities, the ARP 2600 was groundbreaking for its time and inspired the likes of Herbie Hancock, Vince Clark or Joe Zawinul to explore completely new possibilties of musical expression, many of which ended up in classic recordings. The Behringer 2600, a new, modernised and compact version of the original classic, was developed in collaboration with British analog guru AMSynths and retains all the sonic capabilities of its illustrious predecessor. Each original circuit has been painstakingly recreated to contemporary standards, and its format has been reduced from the original to fit in a 19" rack. The Behringer 2600 retains all the features of the original ARP 2600 and has added functionalities of its own, such as MIDI, dimmable LED faders and a digital reverb. Like the original creation by Alan R. Pearlman, the Behringer 2600 can be directly connected to other modular synthesizers and analogue sequencers, and thus become an integral part of a much larger and more powerful system.

Duophonic analogue synthesizer

The 2600 is a powerful analogue synthesizer with three oscillators and two switchable LFOs which can be assigned to a VCO or even used independently. The Behringer 2600 includes differential VCA inputs, an ADSR envelope section with scaling options, and other functions such as noise generators, S&H (Sample and Hold), an assignable low-pass filter as well as an inverter option on the voltage processor. The LFO and portamento sections, which used to be located on a separate keyboard, are also integrated into the main chassis. The original spring reverb of the ARP 2600 has been replaced by a commensurate digital emulation. The main signal path and the assignments of each modulation are conveniently controlled via faders, which can also be visualised via LED colour indicators. For greater flexibility, the signal flow can be modified via patch connections and expanded with external devices. Another features of the 2600 is its Duo Voice Mode, which uses a second oscillator to play two notes simultaneously whereas the original model was exclusively monophonic.

An affordable and successful replica

For most people, owning an ARP 2600 seemed like an unobtainable dream, until now, that is. The original units are very rarely available anymore, and when they are, they are prohibitively expensive. DIY projects do exist and crop up from time to time, but they require a lot of time and expertise to build – and also come with a high-end price tag. The Behringer 2600 offers an affordable version of the classic synth for the first time, and can be picked up by small studios or taken on tour without hesitation. This versatile synthesiser will appeal mainly to musicians who are familiar with the semi-modular concept, with a view to integrating it into a larger, more complex environment. The original ARP 2600 can be heard in many famous production recordings, whether prog rock, fusion or electronic music. This modern version will also naturally suit either style - and is also a noteworthy figure in the field of sound design and SFX - the voice of Star Wars’ robot hero, R2-D2, being a prime example.

About Behringer

The company, which was founded in Germany by Uli Behringer and now manufactures its products in China, has been known for affordable and great-value equipment since its very first product, the Studio Exciter F. An array of mixing consoles (such as the Eurodesk MX8000), signal processors, and later sound amplification and monitoring equipment, has made it possible for countless musicians to fit out their home studios, practice rooms, and mobile PAs within budget limits that were previously unthinkable. The acquisition of other companies, including Midas, Klark Teknik, and TC Electronic, meant that new product groups were added - and also resulted in the technical expertise of these companies being incorporated into product development.

Compact rack synth

As a semi-modular synthesiser, the 2600 can play to its strengths in a modular setup by expanding on them. In the studio, it will link up perfectly with a multitrack analogue sequencer to rhythmically control not only the oscillators but also an array of other functions. The Behringer 2600 can also interact with other modular systems, thereby expanding its capabilities via additional sound and control modules. The original ARP, though ‘portable’, was housed in a rather bulky and heavy ‘suitcase’ for transport. The Behringer's 2600, on the other hand, can be built into a conventional 19" transport case and easily taken to live gigs. The Behringer 2600 is also an extremely capable and expressive standalone instrument. Even outside a modular context. Its flexible and clear structure allows sound and modulation patterns to be quickly and intuitively created, either directly on the main chassis or via external performance-oriented devices.

Wanted to Love, But Typical Poor Behringer Quality
SF Matt 09.07.2021
I'm not quite sure of what to make of Behringer. I love that they are resurrecting classic analog synths, but baffled by the choice of poor quality components and poor quality control. I was very excited to receive my 2600, and it does sound great. However, out-of-the box some of the default normalizations weren't working properly and I got stuck in a rabbit hole with Music Tribe support trying to resolve. Now they are telling me that I can no longer return to Behringer, but must return to Thomann. I live in the US, and am hoping there is a US-based service center I can ship to - otherwise will be too cost-prohibitive to get repaired.

Over the last two weeks, I have a new issue with the synth - when I turn it on, there is no audio, although MIDI is passing through to a connected device and all LEDs light up, etc. I need to turn the unit on multiple times (today on and off twenty times) before the synth will make a sound. Disappointing - I would be delighted to pay many hundreds more if the gear actually worked and was built to last.


Excellent Synth
David Kellett 08.11.2021
This is a great synth. I have a modular system plus several semi modulars but the 2600 is a thing all to itsself. You can approach it as a semi modular but it’s really like a modular system in itself. Yes it can make noise straight out the box as it has normaled connections but once you get the patch cables out it really gets interesting. It’s clear to see why the original ARP was so revered the design is just so flexible and it has a “sound” all of its own.


Hippie flower power machine

Well, it took me a full day & night to figure out how to get any sound out of it. It is most exciting, once I figured out all the patching. The filter is just like from the flower power era, hippie style with no haute couture. The reverb sounds to me like more than retro vintage, but heck, that's the style of this 1970's synth hippie. I tried lots of digital synths before, returned all of them, and finally found in this 100% pure analog synth a reason to make music instead of being a computer technician.

Rob Keeble at AM Synth is the geneous behind this recreation of the ARP 2600. I honestly don't think there is a better version of it.
