The ND-1 is the brand-new audio DAC meticulously crafted by Matrix Audio for separates Hi-Fi systems. Embracing a philosophy of simplicity, it focuses entirely on the critical aspects of D/A conversion. With sound quality as its foremost priority, the ND-1 combines a rigorously engineered circuit architecture with professional tuning to deliver a clean, transparent and low-distortion presentation. Its classic, warm tonal character faithfully reveals every detail and emotion of the music - crafted for audiophiles who seek the most authentic, delicate and lifelike reproduction of the original recording.

The ND-1 is equipped with a full range of digital inputs, including optical, coaxial, AES/EBU, IIS-LVDS, and both USB Type B and Type C. Beyond compatibility with standard S/PDIF digital signals, it also allows simultaneous connections to smartphones, tablets and PCs via different USB interfaces. All digital inputs feature electrical isolation design, effectively blocking common-mode interference and ground loop noise between the source device and the DAC circuitry, ensuring pure and stable transmission of audio data.

The ND-1 features AKM's flagship chipset combination: the premium delta-sigma modulator AK4191EQ paired with dual premium DAC AK4499EX. While the AK4191EQ handles high-precision digital processing and reclocking, the two AK4499EX chips adopt an independent channel architecture, dedicated to the digital-to-analog conversion of the left and right channels. This '1+2' array architecture effectively suppresses jitter, optimizes channel separation and phase consistency, and achieves an exceptional signal-to-noise ratio and dynamic range.

The ND-1 features a custom-build ultra-low phase noise femtosecond clock, providing a high-precision reference signal for the D/A conversion circuit. In addition, it incorporates a high-performance DPLL clock synthesis circuit derived from the brand’s flagship MS-1, supporting an external clock reference mode. When paired with the Matrix Audio SC-1 Audio Grade Reference Clock, the system’s full performance potential is fully realized—capturing the most delicate nuances and dynamic contrasts in music, and delivering a sound that is transparent, composed, richly layered, and vividly lifelike.
