Six channels. One unified setup.
With four stereo channels and two mono channels, the 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 FX send for flexible mixing and performance control. All inputs use compact 3.5 mm mini-jacks, ideal for volca units, NTS instruments, and other desktop gear.
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 FX for spatial processing, while a master TOTAL FX section shapes the entire mix. Add delay, reverb, modulation, drive, and compression to bring depth, movement, and cohesion to your sound.
Hands-on control for live performance
Each channel includes dedicated CUE and MUTE controls. Preview sounds through headphones before bringing them into the mix, or create instant drops and transitions with responsive muting.
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 OUT to control external hardware. Standard 1/4" outputs provide reliable connection to studio and live systems.
Compact, stable, built to last.
The steel body provides a solid foundation that stays in place even in fully patched setups. Despite its small footprint, the NTS-4 is built to handle real-world performance and studio use.
Designed for compact rigs
The 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.
Build it. Make it yours.
As part of the Nu:Tekt series, the NTS-4 is a simple DIY kit that can be assembled with ease. Once built, it becomes a durable, high-quality performance mixer ready for long-term use.
