Korg NTS-4 Mesa de mistura

A compact performance mixer for modern hardware setups
Build the perfect bridge for your music. The NTS-4 brings the flexibility of the Nu:Tekt series to a compact performance mixer kit designed for today’s hardware setups. With six channels (two mono and four stereo minijacks), built-in effects, and USB connectivity, the NTS-4 makes it easy to mix and perform with volca units, NTS instruments, modular gear, and other desktop synths in one place, supporting up to 10 audio signals in a single setup.

From the integrated effects to the steel chassis, every part of the NTS-4 is designed to turn your collection of instruments and gadgets into a professional-grade creative hub.

Small Footprint. Massive Control.
Designed to sit alongside the volca series and other compact instruments, the NTS-4 is ideal for small hardware setups that need a dedicated performance mixer. It features six channels (four stereo and two mono), making it easy to combine synths, drum machines, and modular gear in a single, streamlined setup.
An internal attenuator can be switched between line level and modular level, allowing the mono inputs to integrate directly with Eurorack systems. Dedicated stereo SEND and RETURN connections also make it easy to incorporate external effects into your signal chain.
To ensure reliable connections in any environment, the main outputs use standard 1/4" phone jacks. The NTS-4 simplifies routing and reduces cable clutter, so you can focus on performing and shaping your sound rather than managing your setup.

(*) The jumper pin position needs to be set to either line signal or modular signal levels before assembly.

Master your sound.
The NTS-4 includes two independent stereo effects engines designed for performance and sound shaping. Each channel features a dedicated SEND FX control for effects such as delay, reverb, and chorus, with a TOTAL FX engine on the master output, with processing such as filters, modulation, drive, and compression to shape and unify the overall mix.

Each channel also includes CUE and MUTE buttons. The CUE system lets you monitor a channel privately through headphones before bringing it into the mix, while the MUTE buttons allow for quick cuts and dramatic breaks. These hands-on controls make the NTS-4 well suited for live performance and real-time mixing.

Expanded connectivity for modern workflows.
The NTS-4 utilizes USB Type-C to integrate perfectly with modern production and streaming workflows. Along with support for both USB-C and AC bus power, the USB-C connection also enables high-quality 48 kHz / 24-bit digital audio transfer between the unit and your PC, Mac, or mobile devices. Mix hardware and software sources effortlessly, or record high-fidelity audio and video of your performance directly to your smartphone.

In addition to audio, USB MIDI support allows you to bridge your digital and analog worlds. Receive MIDI messages from your DAW and route them through the dedicated MIDI OUT output to control your hardware.
Whether you are recording in the studio, streaming, or performing a live set, the NTS-4 provides flexible connectivity for modern music production setups.

Built to stay put. Built to last.
The NTS-4 features a rugged steel body that provides real-world stability. It has enough weight to stay firmly on your desk even when every input is occupied, so you don’t have to worry about the unit shifting during a performance. Despite its compact size, it is designed to function as a reliable central mixer in a hardware setup. As part of the Nu:Tekt series, the unit is assembled by the user, with a straightforward assembly process that can be completed with ease.

Once it’s built, the NTS-4 becomes a high-quality piece of hardware that’s built for years of heavy use in the studio or on the road.
