1047 Multimode Filter/Resonator

The Behringer 1047 is an authentic Eurorack reproduction of the highly sought-after ARP 2500 series 1047 Multimode Filter and Resonator. This powerful module is more than just a standard filter; it's a complex sound-shaping tool offering four simultaneous filter outputs, making it incredibly versatile for creating rich, evolving timbres. With its ability to self-oscillate and function as a sine wave generator, the 1047 is a deep and musical module that can serve as the heart of a subtractive synth voice or as a powerful sound design station.

The 1047 provides simultaneous low-pass, high-pass, band-pass, and notch filter outputs, each with a 12 dB/octave slope. It features manual controls for the filter's center frequency and resonance (Q), which can be pushed into self-oscillation to create a pure sine wave. The filter frequency can be modulated by two independent CV inputs, each with its own attenuator, for dynamic filter sweeps and effects. The module's distinct architecture and sound make it ideal for everything from classic subtractive filtering to creating complex formant sounds and acting as a powerful resonator for percussive signals.
