Korg Nu:Tekt NTS-4 Performance Mixer Kit

Korg Nu:Tekt NTS-4 DIY Mixer Kit

The Korg NTS-4 is a compact DIY performance mixer designed to bring multiple instruments together in one streamlined setup. Built for volca units, NTS instruments, modular gear, desktop synthesizers, and other compact electronic instruments, it offers flexible routing, integrated effects, and USB audio/MIDI connectivity for modern music production and live performance.

Featuring four stereo channels and two mono channels, the NTS-4 can mix up to ten audio signals simultaneously. Every channel includes dedicated level, mute, CUE monitoring, and FX send controls, making it easy to build dynamic performances while maintaining complete control over your mix.

Two independent stereo SEND FX engines provide per-channel effects, while a master TOTAL FX processor adds delay, reverb, modulation, filtering, drive, compression, and more to the overall mix. Designed with Eurorack compatibility, USB-C connectivity, and a rugged steel chassis, the NTS-4 is equally at home in the studio or on stage.
