Behringer 923 Filters – Classic Analog Dual Filter Module for Eurorack Dive into the analog world of vintage synthesizers with the Behringer 923 Filters – an authentic replica of classic 70s circuits like the Modular 35 and 15. This module is made for fans of modular synthesis, vintage tone, and sound designers seeking full control over audio filtering. Product Features Independent low-pass and high-pass filters with separate audio inputs and outputs. Each filter includes its own cutoff frequency knob (10 Hz to 10 kHz), enabling precise tonal shaping. Additionally, the module offers two noise types (white and pink) with independent outputs – perfect for filtered noise and percussion textures. Optimized for Modular Systems Built with a solid metal panel and ergonomic knobs, this 8 HP module fits easily into any Eurorack case (~35 mm depth). Fully compatible with Eurorack systems, it integrates smoothly with other modules and is ideal for vintage signal shaping and noise generation. Applications Perfect for noise sculpting, ambient soundscapes, subtle signal cleaning, or vintage tonal coloration. Use the filters in series or parallel to create bandpass effects or dense harmonic textures. Popular in modular synthesis, ambient music, rock, jazz, and experimental electronics. Technical Specifications Format: Eurorack (8 HP, ~35 mm depth) Current draw: +12 V – 35 mA, –12 V – 45 mA Low-pass filter: cutoff from 10 Hz to 10 kHz High-pass filter: cutoff from 10 Hz to 10 kHz Noise generator: white and pink noise with independent outputs No voltage control (manual only) Materials & Build A point-to-point replica of classic Moog circuits using JRC4580 ICs and 330 nF film capacitors. Built in a solid steel enclosure with design cues from the original. Note: knob response may feel stepped near the edges.
