The Behringer 923 Dual Filter Module with Noise is a Eurorack-compatible low-pass and high-pass filter module based on the authentic circuit designs from the Moog Modular System 35 and 15. The discrete circuitry of the Moog Modular System has a very distinctive sound and was used by artists like Keith Emerson, Stevie Wonder, Tangerine Dream, and many other pop, rock, and jazz musicians.

The 923 Dual Filter Module features separate low- and high-pass filters, each with their own dedicated frequency cutoff controls. The low-pass filter removes high frequencies from 10 Hz to 10 kHz, while the high-pass filter removes low frequencies from 10 Hz and 10 kHz. Each filter offers dedicated 3.5 mm inputs and outputs, offering true independent signal routing.

Additionally, the 923 comes with a white and pink noise generator, each available on two parallel 3.5mm jacks. Sweeping white or pink noise signals through a filter can build tension and excitement in your songs. Noise is also a great tool for building percussive sounds. A power ribbon cable and mounting screws are included.
