Legendary analog quad gate & multiples module for Eurorack.

The '80s 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. Modular synths have become more and more popular with professionals and enthusiasts over the years and they’re about to get even better.

This is the Behringer SYSTEM 100 173 QUAD GATE/MULTIPLES. 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 173 QUAD GATE/MULTIPLES in with your existing rig to expand its capabilities and you’re sure to have a lot of fun.

The SYSTEM 100 173 QUAD GATE/MULTIPLES Module features 4 signal gates (switches) with buffered audio inputs and outputs for immediate signal switching. This provides users the option to choose between a control gate operation, non-inverting (active high) input or an inverting (active low) input.

6-channel multiples, each with 4 floating parallel connectors, are available for optimal signal integrity. You can now send out your signal to other modules to help you create more intricate patches and deliver more compelling sounds from one source.

Eurorack Ready
Installing the SYSTEM 100 173 QUAD GATE/MULTIPLES is simple as it was designed to fit into a standard Eurorack case. Just connect the power cables to the power supply and screw in the module using the included screws. This allows for the SYSTEM 100 173 QUAD GATE/MULTIPLES to be mixed with other synth modules for a truly unique set up.
