Behringer 2500 Series 24 dB Low-Pass VCF and VCA Module for Eurorack

This is the Behringer 2500 series FILTAMP MODULE 1006. An authentic reproduction of the original "System 2500" circuitry from the 70's that can fit in a standard Eurorack case. The best part? Its at a very affordable price. Mix the FILTAMP MODULE 1006 in with your existing rig or start your modular synth journey from here. Either way you're sure to have a lot of fun.

The FILTAMP MODULE 1006 is a classic voltage controlled 24 dB per octave low pass filter, the filter is a matched transistor ladder design followed by a matched transistor VCA for a vintage sound. The 1006 filter is equipped with a filter frequency control, a resonance control capable of self-oscillation, 3 summed CV inputs all with independent attenuators for maximum flexibility, the 2 filter signal inputs are also equipped with 2 dedicated attenuators so act as an input mixer.

The VCA has an amplifier gain control which is summed with the CV inputs, an exponential or linear response switch and 2 summed CV inputs with attenuators. All this lets you shape your sound to perfection
