Behringer MULTIMODE FILTER / RESONATOR MODULE 1047 2500 Series 12dB State Variable Filter Module

Here's What Behringer say: 

Modular Synthesis

The first 2500 series synth modules came out in the 70s and tended to be extremely expensive. They were mainly all discrete transistor designs with some op-amps as at the time op-amps were high cost. The discrete circuitry gave the modules a very distinctive sound and were used by artists like The Who, Jean Michel Jarre, Vangelis, Kraftwerk and so many more, giving us some of the greatest records and film soundtracks we’ve ever heard. Modular synths were a landmark development in electronic music and today, it’s about to get better.

MULTIMODE FILTER/RESONATOR MODULE 1047

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.

MULTIMODE FILTER RESONATOR

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.

Features 

• Classic-sounding 1047 analog multi-mode filter and resonator module from the '70s
• Authentic reproduction of the circuitry from the "2500" Series
• Consists of a highly resonant 12 dB state-variable filter capable of proving a wide variety of formant shaping and tonal modulation
• Filter simultaneously provides high-pass, band-pass, low-pass and notch outputs
• Coarse and fine controls adjust the cut-off frequency of the filter from 16 Hz to 16 kHz with 2 external control signal inputs and attenuators
• Resonance (Q) control adjusts the level of the resonant peak from 0 to 512 with an external control signal input and attenuator
• Keyboard percussion feature allows the filter to generate a wide range of percussive sounds
• A keyboard gate signal is connected to the external input with a keyboard CV connected to a frequency control input
• Striking a key will create percussive sounds when the Keyboard Percussion mode is activated
• When the keyboard is released the filter tone damps at a rate determined by Final Q
• Eurorack specs: 16 HP, XX mA +12 V, XX mA -12 V
