NU-X NAI-24 2 Channel Audio Interface

NAI-24 is designed for personal studios; it is compact and equipped with high-quality audio transformers. It features a pure Class A discrete transistor microphone preamp with up to 71dB of gain. Inspired by the classic 76 compressor, it includes a convenient and easy-to-use pure analogue compressor. With support for a sampling rate of 32‐bit/192kHz, it allows for switching between two audio interface modes to accommodate different usage environments.

Utilising the FET type 76PRE compressor circuit, it employs pure hardware circuits for better tonal quality and offers multiple preset modes through digital control for various applications. The input channel uses high-dynamic pure Class A discrete transistors, achieving a maximum gain of 71 dB. Each input channel has a built-in boost mode and 3 different compression modes.

Boost Mode: Provides an additional 8dB of gain to the overall preamp, bringing the total microphone preamp gain to 71 dB.

Vocal Compression Mode: Designed with moderate attack and release characteristics based on vocal performance, delivering a smooth sound.

Guitar Compression Mode: Fast response and smooth release specifically set for guitar/bass, resulting in a more balanced and consistent volume.

Live Streaming Compression Mode: This mode offers the fastest compression characteristics, ensuring signal integrity and clarity during live broadcasts.
