KM has made super clean audio more accessible, so you can focus on the music. This is a next generation audio multi-tool that can meet all your needs as an artist, whether you're in the studio or on the road.

K-Mix features 2 ultra-accurate, high-efficiency, low noise μPre preamps, and a precision opto-tactile control surface designed from the ground up for an unprecedented level of control. 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.

Three essential devices in one portable package!
The K-Mix is a Swiss Army Knife for the studio and stage. It works as a high quality audio interface to get your music into and out of your computer. It is a fully programmable digital mixer with onboard effects, custom configurable presets, and no moving parts to break off in your bag. It’s a MIDI control surface with three banks so you can control parameters of your DAW or external hardware synths and effects right from the board!

Professional Sounding High Quality Audio
The analog front end of K-Mix boasts ultra-low distortion and noise combined with a flat frequency response out to 40kHz. This preserves the crystal clear harmonic content of the source material when mixing and recording. KM uses high end AKM convertors for the highest quality sound. Amazingly, the whole thing can be run on USB bus power, which is simply a marvel of modern engineering and component design.

"It’s an entire console in the smallest portable package ever” - Joe Chiccarelli (Producer, Frank Zappa, White Stripes)

"This is about the coolest thing EVER!" - Sylvia Massy (Producer, RHCP, Tool)

"K-Mix is an extremely usable, compact console that would be equally at home at the centre of a DAW setup, as a PA mixer for a solo artist, duo or small band, or as a submixer in a keyboard or modular synth setup… a very attractive option for many musicians." - Sound On Sound (July 2016)

“If you are looking for a control surface, a surround-capable audio interface, and a digital mixer with DSP, K-Mix is an extraordinary bang-for-the-buck synergy of all three.” - Electronic Musician Magazine (July 2016)
