Expand your Eurorack setup with the 4MS Listen Four — a compact, versatile 4-channel stereo mixer perfect for monitoring, summing, or final output. It features two stereo input channels and two mono input channels with pan knobs, so you can blend signals from synths, drum machines, effects, and more.
You get both a main 1/8\ output (switchable between line and modular level) and a dedicated headphone output with its own volume knob. Low noise, low crosstalk, and clean sound mean your mix stays clear and punchy. It can even be daisy-chained with other Listen modules for bigger mixing setups.
Power via Eurorack supply (not included). Ideal for live performers, studio producers, or anyone who needs a reliable, high-quality mixer in their modular system. Small footprint, big functionality. Whether you're mixing voices, processing stereo fields, or just need a clean headphone amp, the Listen Four delivers pro performance in a compact module.
