Modular Synthesis The 80s was the golden age of electronic music. Synthesizers were at their prime and almost every hit song and movie soundtrack at that time had a synth in one form or another. Modular synths have become more and more popular with professionals and enthusiasts over the years and they’re about to get even better. SYSTEM 100 121 DUAL VCF This is the Behringer SYSTEM 100 121 DUAL VCF Module. An authentic reproduction of the original “System 100M” circuitry from the 80s that can fit in a standard Eurorack case. The best part? It’s at a very affordable price. Mix the 121 DUAL VCF in with your existing rig or start your modular synth journey from here. Either way you’re sure to have a lot of fun. Inputs The 121 DUAL VCF features 3 CV inputs and 3-channel mixers per VCF; allowing you to independently mix all input signals. All of these inputs have their own attenuators to provide you more control over each signal that goes into the module. Filter Controls Each VCF has its own output accompanied by a resonance slider that boosts resonance frequencies and a cutoff control to adjust the cutoff frequency of the lowpass filter. The 121 DUAL VCF also features a 3-mode Fixed HPF switch where you can select between Off, 1 (1 kHz), 2 (2 kHz) or 3 (5 kHz). Combine this with the resonance and cutoff sliders to create intricate and interesting patches. Eurorack Ready Installing the 121 DUAL VCF is simple as it was designed to fit into a standard Eurorack case. Just connect the power cables to the power supply and screw in the module using the included screws. This allows for the 121 DUAL VCF to be mixed with other synth modules for a truly unique set up.
