The Behringer System 100 305 EQ/MIXER/OUTPUT Module brings authentic 1980s “System 100M” circuitry into the modern Eurorack format at a price that won’t break the bank. This parametric EQ, mixer and headphone amplifier combination serves as both an excellent addition to existing modular setups and a brilliant starting point for newcomers to the modular synthesiser world.
At the heart of the 305 lies a comprehensive 4-channel EQ section featuring dedicated level, bandwidth and frequency controls that sweep across the entire audible spectrum from 20 Hz to 20 kHz. The dual outputs allow you to route signals to separate modules for enhanced modulation possibilities and creative waveform manipulation, whilst the handy bypass switch lets you instantly compare your EQ’d signal against the original for precise tone shaping.
The integrated 4-input mixer adds serious versatility with individual pan and level controls for each channel. Output options include both mono and stereo configurations via 3.5mm and ¼” connections, giving you flexibility for various studio and live applications. The independent headphone output with its own level control ensures you can monitor your mix privately without affecting the main signal path.
