K-Mix is an innovation: an unbreakable, 8-in/10-out audio interface and programmable mixer. K-Mix features 2 ultra-accurate, high-efficiency low noise μPre preamps, and a precision opto-tactile control surface that was designed from the ground up for an unprecedented level of control. We've made super clean audio more accessible, so you can focus on the music.

K-Mix is a go-anywhere, fully-programmable, audio multi-tool that can meet all your needs as an artist, whether you're in the studio or on the road. With no moving parts, K-Mix can be transported in a backpack without the fear of snapping off a fader or knob, while still giving you unrivaled audio quality, mixer functionality, and control.

Programmable Mixer
K-Mix is a fully programmable mixer that features flexible routing, per-channel DSP, and can function without a computer.
