Chainable Mono / Stereo Audio Utility Mixer

Mixup is a compact, versatile and expandable audio mixer for eurorack format. It has eight inputs (6 on the front panel) and two outputs. Inputs 1 and 2 are single-channel mono inputs, each with its own mute switch and level control; Input 3 is a dual-channel stereo input with a shared mute and level control; and input 4 is an auxiliary unity-gain, non-mutable stereo input.

Using bus connectors on the back panel, you can chain multiple Mixups together in series, giving you the ability to mix together even more inputs, or to create sub-mixes for routing around larger systems.

Because Mixup is designed specifically for audio (and not for CV mixing), it uses AC-coupled circuitry (which reduces the potential for ‘pops’ when muting and unmuting audio), and it uses audio-grade, logarithmic attenuators for a smooth, even response across the entire volume range.
