Professional AD/DA Conversion, Pure Sound Precision 
Equipped with high-quality, professional AD/DA decoding chips from the renowned manufacturer AKM (Asahi Kasei Microdevices).

A Tribute to Legends 
Utilizing 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 fastest compression characteristics, ensuring signal integrity and clarity during live broadcasts.

Audio Transformers: A High-Quality Choice 
Investing in studio-grade audio transformers at the main output (1L/2R), providing warm sound characteristics and achieving electrical isolation to avoid ground loop interference.
(Note: Even when connecting unbalanced outputs at 1L/2R, balanced output signal strength is still maintained.)

Simple and User-Friendly 
The NAI-24 is a user-friendly 2-input, 4-output audio interface, providing independent 48V phantom power control and LINE IN switching buttons. Features include HI-Z input, dual headphone independent monitoring, soft/hard monitoring mix adjustment, one-click stereo mode switching, and one-click loopback.

With an ultra-low latency of 3.17ms at 192kHz 32 sample buffer, it meets professional needs.

By long-pressing the (OUT 3/4) button, you can route the Output 3/4 signal to Headphone 2 for monitoring. (e.g., When playing backing tracks during a performance, you can set the metronome track separately to (OUT 3/4) and send it to the drummer via Headphone 2.)

One Pair? No, You Need Two Pairs 
A/B Mode: In this mode, you can connect active monitor speakers to the outputs (1L/2R and 3L/4R) simultaneously, and achieve one-click monitoring switching by pressing the (OUT 3/4) button.

Let Me Hear It 
Recording Mode: In this mode, when using the main channel (1L/2R), pressing the (OUT3/4) button allows you to monitor the sound sent to the 3/4 channels with one-click. (e.g., the sound engineer needs to temporarily monitor the tracks sent to the recording musicians.)

Add External Effects to Existing Recordings 
In recording mode, easily connect to various rack and external effect devices for re-recording
