Stereo audio is becoming more popular in the rack as more effects make it over to eurorack. Mixup makes is easy to combine your mono and stereo sources into a single stereo mix. You have mute and level control over the first three channels and, using a rear connector, you can chain multiple Mixups together into a hidden 5th stereo channel without using up channels on the front panel.

Mixup is a versatile, 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.
