Behringer 305 EQ Mixer Output Eurorack Module

Behringer 305 EQ Mixer Output is a Eurorack module designed for modular synthesizer systems. It enables parametric equalization, signal mixing, and output monitoring for modular users, supporting audio shaping and signal routing workflows. This makes it ideal for Eurorack setups where tonal control, signal mixing, and monitoring are required.

The module combines a multi-band parametric EQ section, a mono mixer, and a headphone output amplifier in a single Eurorack module. It also includes an internal oscillator for reference tones and signal testing within modular patching environments.

Within a modular system, it can be used to shape frequencies, combine multiple signals, and route audio to monitoring outputs. Its EQ bypass and multiple output paths support patch evaluation and signal routing to mixers, interfaces, or other modules.
