Legendary analog parametric EQ, mixer, and output module for Eurorack. A parametric EQ, mixer/oscillator, and headphone amp combo that’s an authentic reproduction of the original System 100M circuitry from the 80s, designed to fit in a standard Eurorack case. The 80s was the golden age of electronic music, with synthesizers at their prime, influencing nearly every hit song and movie soundtrack. Modular synths have gained popularity among 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, offered at a very affordable price. You can mix the 305 into 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 to 20 kHz. Using the two outputs of this section, you can patch signals to two different modules for extra modulation and waveform sculpting possibilities, and even switch between EQ’d and bypass modes for quick comparisons.
