Overview

A parametric EQ, mixer/oscillator and headphone amp combo in one module.

The Behringer System 100 305 EQ/MIXER/OUTPUT Module is a parametric EQ, mixer/oscillator and headphone amp combo. It's an authentic reproduction of the original System 100M circuitry from the 80s that can fit in a standard Eurorack case. Mix the 305 in with your existing rig or start your modular synth journey.

Sculpting Your Masterpiece
The 305 allows for maximum tone shaping. Its 4-channel EQ section, complete with level, bandwidth and frequency controls, 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. You can 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 1/4” 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.
 
Whether you’re just getting into modular synths or looking to complete your collection, the 305 EQ/MIXER/OUTPUT module from Behringer is a great tool to have when creating amazing music.
