Authentic 80s analogue filtering meets modern Eurorack convenience with the Behringer SYSTEM 100 121 DUAL VCF Module. This faithful reproduction of the legendary “System 100M” circuitry brings classic filtering capabilities to your modular setup, perfect for expanding existing rigs or launching your modular synth adventure.
Each VCF section provides comprehensive control with 3 CV inputs and dedicated 3-channel mixers, allowing independent signal mixing with individual attenuators for precise level control. The module features resonance sliders that boost resonance frequencies alongside cutoff controls for adjusting the lowpass filter’s cutoff frequency, giving you detailed command over your sound shaping.
The 121 DUAL VCF includes a versatile 3-mode Fixed HPF switch offering Off, 1 (1 kHz), 2 (2 kHz) or 3 (5 kHz) settings. Combined with the resonance and cutoff controls, this creates opportunities for complex and engaging patch creation that captures the character of vintage analogue filtering.
Installation into standard Eurorack cases is straightforward – simply connect the power cables and secure with the included screws. This seamless integration allows the 121 DUAL VCF to blend effortlessly with other modular components, creating truly personalised synthesiser configurations.
