Korg NTS-2 Oscilloscope Kit with Spectrum Analyzer and Audio Tools

Korg Nu:Tekt NTS-2 Oscilloscope Kit

The Korg NTS-2 is a compact, multi-function oscilloscope kit designed for musicians, synthesizer users, and audio engineers who need a portable tool for visualizing and analyzing audio and control voltage (CV) signals. It combines an oscilloscope, spectrum analyzer (FFT), waveform generator, and tuner in a single handheld device.

Built as part of Korg’s Nu:Tekt DIY series, the NTS-2 is easy to assemble and does not require soldering. It is widely used in modular synth setups, DAWless rigs, and studio environments for signal monitoring, troubleshooting, and sound design.

Key Features

• 4-channel oscilloscope with multiple display modes
• Real-time FFT spectrum analyzer (20 Hz – 20 kHz)
• Dual waveform generator (sine, square, triangle, saw, noise, pulse)
• Built-in tuner with multiple display modes
• Supports audio and CV signal analysis
• Dual stereo inputs and outputs for flexible routing
• USB-C or AAA battery powered operation
• Compact portable design for studio and live setups

Signal Visualization and Analysis

The NTS-2 allows real-time visualization of audio waveforms and control voltages, making it useful for debugging synth patches, monitoring signal integrity, and learning sound design concepts.

Its multiple oscilloscope display modes, including XY (Lissajous) and stereo views, provide detailed insight into signal behavior across different channels.

Built-In Sound Tools

In addition to measurement functions, the NTS-2 includes a flexible dual waveform generator that can act as audio oscillators or low-frequency control sources. This makes it useful for modulation, testing, and experimental patching in modular systems.

The integrated tuner provides fast and accurate tuning for instruments and audio sources, making it practical for both studio and live environments.

Compact and Portable Design

Designed for portability, the NTS-2 is lightweight and small enough to fit into a modular synth rig or desktop setup. It can be powered via USB-C or batteries, making it suitable for both studio and mobile use cases.

Its simple interface and clear display allow quick access to signal analysis tools without complex setup.

Ideal Applications

• Modular synthesizer systems
• DAWless music setups
• Audio signal troubleshooting
• Sound design and experimentation
• Studio monitoring tools
• Educational use for audio and electronics learning
