NUX NAI-24 USB Audio Interface – 2-In/4-Out 32-bit/192kHz with Analog Compressor

The NUX NAI-24 is a compact 2-in/4-out desktop USB audio interface built for home and project studios. It pairs pure Class-A discrete transistor mic preamps with a built-in analog FET "76"-style compressor, AKM AD/DA converters and studio-grade audio transformers on the main outputs, for warm, clean recordings straight into your DAW.

Key features

• 2 inputs, 4 outputs: two XLR/6.35mm combo inputs with Mic, Line and Hi-Z (instrument) operation, main outputs 1L/2R plus auxiliary outputs 3L/4R.
• Up to 32-bit/192kHz with professional AKM AD/DA conversion and ultra-low latency (3.17ms at 192kHz, 32-sample buffer).
• Class-A mic preamps with up to 71dB of gain in Boost mode, and independent 48V phantom power per channel.
• Built-in analog FET compressor (76PRE circuit) with Vocal, Guitar and Live Streaming modes.
• Transformer-coupled main outputs for a warm character and ground-loop isolation.
• Two independent headphone outputs with routable channels, so a second player can get their own mix (for example a click track).
• A/B monitor switching: connect two pairs of studio monitors and switch between them with one button.
• Ultra-low-latency direct monitoring with adjustable mix, stereo mode and loopback for streaming.
• USB bus-powered, no external power supply needed.
• Includes a licence for Cubase 13 LE recording software.
