Behringer 1047 Multimode Filter/Resonator Eurorack Module

Designed to shape the raw sound of any oscillator, the Behringer 1047 is the 2500 series’ all-analog multimode filter and resonator module. Employing a state variable filter design, the Behringer 1047 features four independent outputs for lowpass, highpass, bandpass, and notch filter modes, providing incredible power to manipulate the timbre of your patches. Its ample controls include coarse and fine frequency adjustment, resonance Q for setting the width of the resonant peak, and a notch frequency offset knob. Plus, the Behringer 1047 offers two CV-patches for modulating the frequency parameter and one patch point for tweaking the resonance via CV. Synthesists at Music Bliss recommend the Behringer 1047 and the rest of the Behringer 2500 Series module to Eurorack novices and seasoned patch masters alike. They’re an affordable way to build the modular synth rig of your dreams!

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
