Behringer SYSTEM 55 Modular Synthesizer with 38 Modules

The first System 55, 35 and 15 synth modules came out in the early '70s and tended to be extremely expensive. They were mainly all discrete transistor designs as op-amps at the time were very high cost. The discrete circuitry gave the modules a very distinctive sound and were used by artists like Keith Emerson, Stevie Wonder, Tangerine Dream and so many more, giving us some of the greatest records we've ever heard. Modular synths were a landmark development in electronic music and today, it's about to get better.

SYSTEM 55
Behringer is bringing back all those amazing modular synths that you've all come to know and love and they're putting them in one neat package that'll surely blow you away. Enter the Behringer SYSTEM 55. This is a pre-assembled "System 55" modular synthesizer that comes packed with 38 of their vintage sounding synth modules, mounted and fully powered in two super-sturdy EURORACK GO cases. It even comes with some extra space for another one of our favorite things...more modules!

The Ultimate Synth!
The SYSTEM 55 is an amazing tool for those who want the ultimate modular synthesizer capable of fully scoring that next cyberpunk or sci-fi movie from start to finish. This entire setup comes equipped with a 914 FIXED FILTER BANK which features 12 active bandpass filters ranging from 125 Hz to 5.6 kHz with additional Low Pass and High Pass filters and one 923 FILTER MODULE with separate Low and High Pass filters each with their own dedicated frequency cutoff controls and jacks for both pink and white noise. But that's only the start, with the SYSTEM 55 comes with so many more modules, you're sure to have hours and hours of fun creating beats that you can just lose yourself in.

All the VCAs and Envelope Generators!
Is having one VCA a bit too limiting? Then, worry no more as the SYSTEM 55 features five 902 VOLTAGE CONTROLLED AMPLIFIERS with three summed CV inputs and dual audio inputs and outputs. Each module also comes with a rocker switch that allows you to toggle between linear and logarithmic response modes while you can manually set the control voltage with the Fixed Control Voltage knob. Need more envelope generators? The SYSTEM 55 also comes with four 911 ENVELOPE GENERATORS allowing you to create a deeply contoured signal with each of their 4 independent controls for Attack (T1), Decay (T2), Release (T3) and Sustain times from 2 ms up to 10 seconds. Create snappy and percussive sounds or long evolving drones perfect for a funky groove or a brooding soundtrack to your latest techno thriller.

A Step in the Right Direction
A step sequencer has always been at the heart of every synthesizer setup, so of course we had to include one. The 960 SEQUENTIAL CONTROLLER is an 8-step sequencer with 3 rows of CV controls for adjusting the pitch of a signal at that stage. An additional 9th step can also be used to stop the sequence. More variations can be achieved by switching any of the desired Stage Mode Switches to Normal, Skip or Stop. You can even manually trigger each stage by pressing the respective Set button. "But we want more!" we hear you ask, so we decided to include the 962 SEQUENTIAL SWITCH module that transforms the 960 from an 8-step sequencer to a 24-step giant capable of more intricate sequences and beats.

Time to Flex
Adding even more flexibility to the SYSTEM 55, the 961 INTERFACE module converts V-trig to S-trig and vice versa and can even convert any audio source you plug in to a V-trig to drive other modules in your setup. The 903A RANDOM SIGNAL GENERATOR provides two white and pink noise sources that you can patch to other modules in the SYSTEM 55.

There's More!
The SYSTEM 55 also comes with a 992 CONTROL VOLTAGES MODULE that allows you to mix and switch control voltages, 904B HIGH PASS FILTER and 904A VOLTAGE CONTROLLED LOW PASS FILTER and a CM1A MIDI-to-CV converter so you can control the SYSTEM 55 with a MIDI keyboard, sequencer or DAW, to truly round out this rig. Behringer even included a few blank panels in case you want to expand the SYSTEM 55 with even more modules! You don't even have to worry about power as the included EURORACK GO cases come with their own PSUs.

Amazing Gear at an Affordable Price
Whether you're just getting into modular synths or looking to complete your collection, the SYSTEM 55 modular synthesizer from Behringer is a great tool to have when creating amazing music.
