Korg Nu:Tekt NTS-4 Performance Mixer Kit brings the flexibility of the Nu:Tekt series into a powerful performance mixer. With six channels, integrated effects and USB audio/MIDI connectivity, it's designed to connect, mix and perform with Korg Volcas, other Korg NTS instruments, modular gear and desktop synths in one streamlined setup.
- 6-channel analog mixer with 4 stereo and 2 mono inputs
- Eurorack-compatible mono inputs with switchable line/modular levels
- Dual stereo send effects and master total effects
- Per-channel cue and mute buttons
- USB-C MIDI and audio (48 kHz / 24-bit)
- Dedicated effects send and return connections
- Rugged aluminum chassis
Six channels, one unified setup
With four stereo channels and two mono channels, NTS-4 makes it easy to combine multiple instruments into a single performance rig, supporting up to 10 total audio signals. Each channel includes level control, mute, cue monitoring and effects send for flexible mixing and performance control. All inputs use compact 1/8" mini-jacks, ideal for Korg Volcas, Korg NTS instruments and other desktop gear. Each channel includes dedicated cue and mute controls so you can preview sounds through headphones before bringing them into the mix or create instant drops and transitions with responsive muting.
Designed for synths and modular gear
The mono inputs support both line-level and modular-level signals via a switchable attenuator, allowing seamless integration with eurorack systems. Dedicated send and return connections make it easy to expand your setup with external effects.
Shape your mix in real time
Two independent stereo effects engines provide per-channel send effects for spatial processing, while a master total effects section shapes the entire mix. Add delay, reverb, modulation, drive and compression to bring depth, movement and cohesion to your sound.
Seamless connection to your setup
USB-C provides 24-bit audio and MIDI connectivity for recording, streaming and DAW integration. Mix hardware and software together, or record directly to your computer or mobile device. MIDI received over USB can be routed through the dedicated MIDI output to control external hardware. Standard 1/4" outputs provide a reliable connection to studio and live systems.
Compact, stable and built to last
The aluminum body provides a solid foundation that stays in place even in fully patched setups. Despite its small footprint, NTS-4 is built to handle real-world performance and studio use.
Build it, make it yours
As part of the Nu:Tekt series, NTS-4 is a simple DIY kit that can be assembled in minutes. Once built, it becomes a durable, high-quality performance mixer ready for long-term use.
Designed for compact performance rigs
NTS-4 is built to sit at the center of small hardware setups, reducing cable clutter and simplifying routing so you can focus on performance.
Frequently Asked Questions: NTS-4 Performance Mixer Kit
What is the Korg Nu:Tekt NTS-4 Performance Mixer Kit?
The NTS-4 is a six-channel DIY performance mixer kit from Korg's Nu:Tekt series that assembles in minutes with no soldering required. It combines an analog mixer, dual stereo send effects, master effects, and USB-C audio and MIDI connectivity in a rugged aluminum chassis built for compact hardware setups.
Who is the Korg NTS-4 designed for?
It's built for electronic musicians running compact desktop rigs, especially anyone performing or jamming with Korg Volcas, NTS instruments, eurorack modular gear, or small desktop synths. If you want to mix multiple instruments, add effects, and record over USB from one central hub, the NTS-4 is designed for exactly that.
How many inputs does the Korg NTS-4 have, and what type?
The NTS-4 has six channel inputs: four stereo and two mono, all on compact 1/8" mini-jacks, supporting up to 10 total audio signals. The mono inputs accept both line-level and modular-level signals via a switchable attenuator, and there's also a 1/8" stereo effects return for external gear.
Does the Korg NTS-4 work with eurorack and modular gear?
Yes. The two mono inputs feature a switchable attenuator that accepts both line-level and hotter modular-level signals, so you can run eurorack voices straight into the mixer. Dedicated send and return jacks also let you patch in external effects.
What effects are built into the NTS-4?
There are two independent stereo send effects engines with chorus, delay, ping-pong delay, hall reverb, and slap reverb, applied per channel. A separate master total effects section processes the whole mix with options including low pass and high pass filters, isolator, flanger, phaser, decimator, drive, distortion, compressor, and limiter.
Can I use the NTS-4 as a USB audio interface for recording?
Yes. USB-C provides 24-bit / 48 kHz audio plus MIDI, so you can record your mix directly to a computer or mobile device, stream, or blend hardware and software in a DAW. MIDI received over USB can also be routed to the dedicated MIDI output to control external hardware.
Do I need a power supply for the NTS-4?
No, the NTS-4 is bus powered over USB-C, and a USB-C to USB-A cable is included. An optional 9V AC adapter is available separately if you prefer not to power it from a computer or USB power source.
What are the cue and mute buttons on the NTS-4 used for?
Every channel has a cue button for previewing that sound in headphones before bringing it into the mix, plus a mute button for instant drops and transitions during a performance. Together they give you DJ-style control over a live hardware set.
Is the NTS-4 hard to build?
No. Like other Nu:Tekt kits, it's a simple DIY assembly that takes minutes and requires no soldering, and the finished unit is a durable performance mixer with a solid aluminum body suited to long-term studio and live use.
Does the NTS-4 have EQ on each channel?
No, the NTS-4 does not include channel EQ or a main EQ. Tone shaping is handled instead through the master effects section, which offers low pass and high pass filters, an isolator, and other processing for sculpting the overall mix.
