Behringer 2500 Series 12dB State Variable Filter Module for Eurorack

This is the Behringer 2500 series MULTIMODE FILTER/RESONATOR MODULE 1047. An authentic reproduction of the original "System 2500" circuitry from the 70's that can fit in a standard Eurorack case. The best part? It's at a very affordable price. Mix the MULTIMODE FILTER/RESONATOR MODULE 1047 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 MULTIMODE FILTER/RESONATOR MODULE 1047 is a classic voltage controlled 12 dB per octave state variable filter, the filter is a matched transistor design for a vintage sound. The 1047 filter is equipped with a coarse and fine filter frequency controls, a resonance (Q) control which acts on all 4 filter outputs, a resonance limit switch prevents signal overload when high levels of resonance are used, the notch frequency/fc control allows the notch frequency to be adjusted up or down from fc as set by the frequency controls, 2 summed frequency CV attenuators and a resonance (Q) CV attenuator for maximum flexibility, the signal input is also equipped with an attenuator. All this gives you endless possibilities of filter curve shape to create the ultimate sound.

The 1047 is the heart of the ARP 2500. Behringer have done an amazing job of recreating this iconic unit. Although not exactly the same as the original, the B1047 has a unique sound and design. It has more resonance than any other filter I have used (like the original) and will compliment any system. Highly recommended.
