Legendary Analog Phase Shifter/Delay/LFO Module for Eurorack

The 80's was the golden age of electronic music. Synthesizers were at their prime and almost every hit song and movie soundtrack at that time had a synth in one form or another.

This is the Behringer SYSTEM 100 172 PHASE SHIFTER/DELAY/LFO. An authentic reproduction of the original “System 100M” circuitry from the 80s that can fit in a standard Eurorack case.

The best part? It’s at a very affordable price.

Mix the 172 PHASE SHIFTER/DELAY/LFO in with your existing rig or start your modular synth journey from here. Either way you’re sure to have a lot of fun.

Phase Shifter

The 172 PHASE SHIFTER/DELAY/LFO comes with a 6-step phase shifter with Modulation Intensity, Shift Frequency and Resonance Controls. Adjusting these parameters can vary the phase effect from a slight warble to an intense swirling effect that add a sense of movement to your music.


The Analog BBD Delay on the 172 also features independent Modulation intensity, Delay Time and Resonance controls. These controls allow you to dial in some amazing chorus and flanging effects that give spaciousness to your tone.

LFO and Gate Delay

You can control when a gate triggers by plugging in a signal to the Gate Delay input on the 172. Here, you can control the gate and delay time for some creative pulse shaping.

A frequency control on the 172’s LFO allows you to change the pitch while the normal and inverted output jacks are ideal for creating ensemble and stereo effects.

Eurorack Ready

Installing the 172 PHASE SHIFTER/DELAY/LFO is easy, and it's designed to fit into a standard Eurorack case.

Just connect the power cables to the power supply and mount the module using the included screws. This allows for the 172 to be mixed with other synth modules for a truly unique set up.
