NAD Master Series M17 (V2i) AV Surround Sound Preamp Processor

Pin It
  • Infinite possibilities await thanks to the M17 V2’s, Modular Design Construction (MDC). Dolby Atmos® and DTS-HD Master Audio combined with Dirac Live® Room Correction delivers hyper-realism that captures every dimension of a performance. Add bit-perfect 4K UHD video processing and the M17 delivers the most accurate sound and image experience. 

    With MDC, all major digital circuits can be upgraded and replaced. Future video formats and surround sound decoders can be easily accommodated. You only need to replace the module you want to upgrade, not the entire AV preamp processor.


    The M17 offers full HDMI video switching and surround sound decoding with 11.1 balanced outputs. It brims with sophisticated features like the high resolution lossless formats from Dolby TrueHD and DTS-HD Masters Audio decoding and object-based audio with Dolby Atmos. The surround mode is automatically detected and the most advanced form of decoding is switched in. Conversion of the encoded digital bitstream is performed with high resolution and extremely linear D/A converters.


    The latest HDMI features, including HDCP 2.2, 4:4:4 color resolution, High Dynamic Range video support and CEC/ARC, are included. Digital inputs and outputs are available in coaxial and optical formats. Digital inputs are converted to analog for use in Zone 2, and you can choose to convert unused tape outputs for Zone 3 and Zone 4 use with independent source selection and volume control. With BluOS® we have also made it easy to add more speakers for listening to music in additional rooms. IR repeaters, 12V triggers to automatically switch amplifiers on and off, and an RS-232 data port makes it easy to connect to highly advanced automated control systems, such as Crestron and Control4. 


    Dirac Live® and its powerful room correction software is built in, including its own calibrated measurement microphone and Dirac Live FULL. Advanced users can build the perfect listening environment that corrects for both the timing and colorations in sound, including the ability to create custom target curves for room response.


    BluOS®, the advanced operating system and music management software is included. When connected to the Internet, it has access to thousands of radio stations and over a dozen high quality music services like Spotify, Amazon Music, Tidal, Deezer, and more. With full support for Master Quality Authenticated (MQA) technology, it has the highest resolution audio performance available combined with the highest definition video performance.


    The sleek TFT touch panel offers five independent AV presets that store speaker level and tone control settings for instant recall, making it easy to  tailor your system for different types of program material. Encoded surround modes like Dolby Digital and DTS are automatically selected if the program is encoded. It also remembers your last used settings when switched in and out of Standby mode.
