NUX NAI-24 2 Input 4 Output USB Audio Interface

NUX NAI-24 2 Input 4 Output USB Audio Interface (NAI24)

The NAI-24 is a compact, studio-grade 2-input / 4-output USB audio interface built for creators and engineers who demand professional sound in a small package. It features a pure Class-A discrete transistor microphone preamp capable of delivering up to 71 dB of gain, enhanced by a built-in analog FET-style 76PRE compressor circuit inspired by classic compressors. Choose from multiple modes—Vocal, Guitar, or Live Streaming—to match your source with optimized compression settings.

Equipped with premium AKM AD/DA converters, the NAI-24 supports sample rates up to 32-bit / 192 kHz. It also includes studio-grade audio transformers on its main outputs for enhanced warmth and electrical isolation, reducing unwanted noise and ground loop issues. The interface offers flexible routing with dual headphone outputs (each independently routed), independent phantom power per channel, HI-Z input, line input switching, loopback, ultra-low latency (3.17 ms @ 192 kHz), and versatile 3/4 output mode for monitoring or routing external signals. Plus, you get Cubase LE included to get started right out of the box.
