Behringer 121 Dual VCF Module

Bring back the sounds of the '80s with the Behringer 121 Dual VCF Module, an authentic reproduction of the original System 100M circuitry. This powerful dual VCF module is designed to fit seamlessly into your Eurorack setup, offering two lowpass filters, each with highpass filter options for creative flexibility. Whether you're sculpting smooth tones or crafting complex effects, this module is built to deliver.

MODULAR SYNTHESIS

The 1980s marked a golden era for electronic music, where synthesizers took center stage in countless iconic tracks and soundtracks. The System 100M was one of the standout modular systems of the time, widely regarded for its rich analog character and versatility. The Behringer 121 DUAL VCF brings that legendary sound and workflow to modern modular setups at an accessible price point.

SYSTEM 100 121 DUAL VCF

The 121 DUAL VCF features two independent lowpass filters, each with cutoff frequency and resonance controls, providing total control over your signal. With three audio inputs and three CV inputs per filter, this module allows you to create rich, evolving sounds with ease. For added creative potential, each filter includes a switchable 3-mode highpass filter, giving you even more tonal shaping possibilities.

INPUTS

The 121 DUAL VCF is built with versatile input options. Each filter has 3 CV inputs and a 3-channel mixer, enabling independent mixing of all input signals. Each input comes equipped with its own attenuator, providing precise control over the modulation and mixing of your signals.

FILTER CONTROLS

Each VCF has its own output, complete with a resonance slider that emphasizes the frequencies around the cutoff point, and a cutoff control to shape the filter’s frequency range. The 3-mode fixed HPF switch lets you select from Off, 1 (1 kHz), 2 (2 kHz), or 3 (5 kHz), offering a variety of highpass filtering options. Combine these features for rich, dynamic filtering effects that can evolve and shift in real time.

EURORACK READY

The 121 DUAL VCF is designed for easy integration into any standard Eurorack case. Simply connect the power cables and mount the module with the included screws. This allows for smooth integration with other synth modules, enabling endless creative possibilities.
