DirectDigital Innovation

DirectDigital amplification offers the highest level of performance. The 35-bit data path with 24-bit coefficients and 62-bit accumulation, and dithered truncation back to 35-bits after DSP functions guarantee the overall 24-bit accuracy. With this degree of resolution, all preamp functions can be accomplished with a new level of precision all in the digital domain. Because of the super high resolution, even 24-bit files are processed without truncation or loss of information.

Uncompromised Connection

Standard inputs include AES/EBU, Asynchronous 24/192 USB, coaxial and optical digital inputs and balanced and single-ended line level inputs including a high performance MC/MM phono stage. Rounding out the picture, a pure Class-A buffer using the latest generation of Super OP Amps provide low impedance balanced and single-ended connections to power amplifiers or active loudspeakers. A remote controls all functions and IR repeaters, 12V triggers, and a serial port to make integration with advanced control systems a snap.

Fine Tune Your System

Because of the massive computing power and high-resolution signal path, some interesting features have also been incorporated to further perfect the listening experience. Want to add a subwoofer to your system? The M12 includes a second order high pass and low pass crossover with selectable frequency. You can even select different frequency knees for each filter. This level of flexibility and precision is made possible by our highly perfected DirectDigital architecture. One of NAD’s most innovative technological advancements— Modular Design Construction (MDC)—does away with obsolescence by providing a simple upgrade path to add future features and functionality. M12 owners can add an optional DD HDM-1 HDMI Module with 3 inputs and 1 output (3D video passthrough) and/or the network audio module, DD BluOS, with music management software that is controlled with an iOS or Android device.

Forward-Thinking MDC

The BluOS MDC Module allows streaming of a variety of music services, HD streaming from a NAS device, and TuneIn radio; plus it gives you full control of your music library. Integrated WiFi/Ethernet and aptX Bluetooth™ connections are also offered with the BluOS Module.

Master Quality Authenticated (MQA)

Master Quality Authenticated (MQA) is a revolutionary end-to-end technology built into every BluOS Enabled music player that captures and delivers master quality audio to any room in your home. All BluOS Enabled music players from NAD include a powerful decoder and audio renderer for the MQA system. The MQA logo shown in the BluOS app indicates that the unit is decoding and playing an MQA stream or file, and lets you know that you are hearing exactly what the artist recorded and approved in the studio.

About NAD

In 1972, a new kind of audio company was born. NAD took form when a large group of audio-industry importers in Europe, all music lovers, set out to develop products that cut through the industry hype. The goal of NAD was to prove that excellent sound quality and excellent value could exist together. It was a formidable goal – some of the most reputable electronics brands of the time were unaffordable to most, while the affordable spectrum of the market was dominated by poor quality imports from global electronics giants. NAD’s founders remained undeterred and their original vision led to an inspiring story of how a group of specialty audio mavericks took on the Goliaths of the audio industry to carve out a unique place of their own.

NAD is dedicated to innovation, performance, value, and simplicity in all their products.
