Description
The Korg NTS-4 is a compact six-channel performance mixer kit from the Nu:Tekt series, designed for modern hardware setups. With four stereo and two mono minijack inputs, built-in dual stereo effects, and USB-C audio interface capabilities, the NTS-4 brings together your synths, drum machines, and modular gear into one professional mixing hub.
Six Channels for Complete Hardware Integration
Four stereo minijack inputs accommodate your Volca units, NTS instruments, and desktop synths, while two mono minijack inputs feature switchable attenuators for Eurorack-level signals. Dedicated stereo SEND and RETURN connections let you integrate external effects into your signal chain. Main outputs use standard 1/4" phone jacks for reliable connections in any environment.
Built-in Dual Stereo Effects
The NTS-4 includes two independent stereo effects engines. Per-channel SEND FX offers delay, ping pong delay, hall reverb, slap reverb, and chorus. A master TOTAL FX engine provides filters, isolator, flanger, phaser, decimator, drive, distortion, compressor, and limiter modes. Each effect is controlled with FX Type and FX Depth parameters.
Performance Controls
Each channel features dedicated controls for level, pan (mono channels), and send FX amount. CUE buttons let you monitor any channel privately through headphones before bringing it into the mix. MUTE buttons enable quick cuts and dramatic performance breaks.
USB-C Audio & MIDI Interface
The USB-C connection delivers 48 kHz / 24-bit digital audio between the NTS-4 and your computer or mobile device. USB MIDI support bridges your digital and analog worlds, with a dedicated 3.5mm TRS MIDI OUT for controlling external hardware from your DAW.
Steel Chassis DIY Kit
Ships as a soldering-free DIY kit that assembles in minutes. The rugged steel body provides real-world stability and weight to keep the unit firmly in place during performance, even with every input occupied.
