Korg’s NTS-4 is a compact solderless DIY kit for users who want a small analog mixer in a desktop hardware setup. The steel-chassis, palm-sized unit sits in the Nu:Tekt line and is presented as a performance mixer rather than a simple routing device.

The six-channel layout provides four stereo minijack inputs and two mono minijack inputs compatible with Eurorack-level signals. The mono inputs include an internal attenuator for switching between line and Eurorack level, and every channel has Cue and Mute buttons so signals can be checked privately in headphones before entering the main mix or cut immediately during performance.

Dedicated stereo Send and Return connections support external effects, while the main left/right outputs use standard unbalanced quarter-inch jacks. Two independent stereo effects engines can run at the same time: channel Send FX offers seven options including delays, reverbs and chorus, while Total FX on the main output provides 10 processing choices including filters, isolator, modulation, decimator, drive, distortion, compressor and limiter; the listed price is $249 USD.
