Behringer 1047 Multimode Filter Resonator Module Modular System

The Behringer 1047 is an authentic reproduction of the classic multimode filter and resonator circuit from the legendary 2500 series. This Eurorack module delivers the warm, vintage character of analog filtering with a 12dB/octave state-variable design. It provides simultaneous high-pass, band-pass, low-pass, and notch outputs, giving you extensive tonal shaping options. The cutoff frequency can be adjusted from 16 Hz to 16 kHz using coarse and fine controls, while the resonance (Q) can be set from 0 to 512 for extreme filtering effects.

In addition to standard filtering, the 1047 features a unique percussion mode. When activated, each key on a connected keyboard triggers a distinct percussive sound, with the decay rate controlled by the Final Q setting. The module includes a keyboard gate input and a frequency control CV input, allowing seamless integration with other Eurorack gear. It requires 16 CV connections and draws XX mA from -12V and XX mA from +12V rails.
