Modular Synthesis

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 100 305 EQ/MIXER/OUTPUT Module. A parametric EQ, mixer/oscillator and headphone amp combo that’s 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 305 in with your existing rig or start your modular synth journey from here. Either way you’re sure to have a lot of fun!


Sculpting Your Masterpiece

The 305 allows for maximum tone shaping with its 4-channel EQ section complete with level, bandwidth and frequency controls that span a wide frequency spectrum from 20 Hz all the way up to 20 kHz. Using the two outputs of this section, you can then patch signals to two different modules for some extra modulation and waveform sculpting possibilities and even switch between EQ’d and Bypass modes for a quick comparison.


Start Mixing

For added mixing capabilities, you can use the 305’s 4-input mixer with individual pan and level controls. The output signal can be in either mono or stereo via 3.5mm and ¼” jacks. Monitor your overall signal though the independent headphone output and its included level control

Eurorack Ready

Installing the 305 EQ/MIXER/OUTPUT is simple as it was 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 305 EQ/MIXER/OUTPUT to be mixed with other synth modules for a truly unique set up.
