Analog low-pass VCF module for Eurorack.
The Behringer 904A Voltage Controlled Low-Pass Filter module brings the warm, rich sound of analog filters to your Eurorack rig. With real-time cutoff and resonance controls, you can shape everything from subtle tone-shaping to aggressive wah effects. The 904A's authentic circuitry replicates coveted vintage synth filters, adding analog magic to your patches. Its 3 CV inputs invite creative modulation from LFOs, envelopes and more. At just 8HP wide, it fits seamlessly into any Eurorack case or System 55 setup. Dial in the perfect tone to make your synthesizer truly sing.
Shape Your Sound With Cutoff and Resonance
The 904A gives you hands-on control over the two most important filter parameters—cutoff frequency and resonance. Adjust the cutoff knob to determine which frequencies get through, from a tight, rounded bass to a shimmering high-end. Turn up the resonance control to accentuate frequencies around the cutoff point, adding bite and presence. Having these filter essentials immediately accessible makes it easy to sculpt sounds in real time.
Get Creative With Three CV Inputs
While the knobs provide basic tone shaping, the 904A really comes alive when you start modulating the cutoff frequency CV input. Patch in an LFO to add rhythmic wah effects or use an envelope follower to have the filter respond to your playing dynamics. With two additional CV inputs, you can also control resonance or modulate between low-pass and band-pass modes. The possibilities are endless when you integrate modulation sources into the 904A's filter circuit.
Vintage Appeal in a Modern Format
Inspired by coveted vintage synths like the Minimoog, the 904A's filter design oozes retro analog character. From smooth, rounded bass to searing resonant peaks, it brings that elusive golden-era tone to your setup. Despite the old-school vibe, it fits right in with 8HP Eurorack modules and Behringer's System 55 reissues. Expand your tonal palette without taking up much space in your modular rig.
Plug In and Start Exploring
The 904A makes it simple to start using vintage-style filtering in your modular patches. With Eurorack power connectivity and a compact 8HP size, it easily integrates into new or existing systems. Dial in the perfect tone to make your synthesizer truly sing. Let the 904A bring sought-after analog flavor to your modular rig.
