Behringer 172 Phase Shifter Delay LFO Eurorack Module

Behringer 172 Phase Shifter Delay LFO is an analog Eurorack effects and modulation module designed for modular synthesis systems and studio environments. It enables phase shifting, short delay processing, gate timing, and low frequency modulation for musicians and sound designers, supporting signal processing and modulation workflows. This makes it ideal for modular setups where time-based effects and modulation control are critical.

The module operates by routing audio and control signals through dedicated analog phase shifter, delay, gate, and LFO circuits. Modulation depth, timing, resonance, and frequency parameters are controlled from the front panel, with separate inputs for audio and control voltage. Normal and inverted modulation outputs allow interaction with other Eurorack modules.

This configuration supports creating modulation movement, short delay effects, and gated signal shaping within a single module. It can be used for ensemble effects, rhythmic modulation, and signal transformation. The module integrates into standard Eurorack systems using common power and mounting formats.
