Surround Yourself with Perfection

The M17 V2i carries on the enviable task of representing
NAD’s finest surround sound performance. Infinite possibilities await thanks to
the M17 V2i’s most impressive feature, Modular Design Construction (MDC), NAD’s
proven method for preventing premature obsolescence. Dolby Atmos®DTS:X and
DTS-HD Master Audio combine with Dirac Live® Room
Correction to deliver hyper-realism that captures every dimension of a performance.
Add bit-perfect 4K UHD video processing and the M17i V2i delivers the most
accurate sound and image experience you’ve ever had. The M17 V2i is
second-to-none in terms of flexibility and up-to-the-minute digital technology.

Fully Featured Surround

The M17 V2i offers full HDMI video switching and surround
sound decoding along with 11.1 balanced outputs. Brimming with a full
complement of sophisticated features like the high resolution lossless surround
formats from Dolby TrueHD, DTS: X and DTS-HD Masters Audio decoding, and now
object-based audio with Dolby Atmos, the M17 provides the highest levels of
performance. The surround mode of the source material is automatically detected
via the digital inputs of the M17 V2i, and the most advanced form of decoding,
based on your setup, is switched in. Conversion of the encoded digital
bitstream is performed with high resolution and extremely linear D/A converters
carefully selected for their performance capabilities.

Flexible Setup

The latest HDMI features, including HDCP 2.2, 4:4:4 colour
resolution, High Dynamic Range video support, and CEC/ARC, are all included.
Digital inputs and outputs are available in both coaxial and optical formats to
make it easy to attach all your digital sources. Digital inputs are converted
to analogue 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. Thoughtful features like discrete On and Off codes, direct access
to inputs and FM station presets facilitates the integration of the M17 V2i
into elaborate remote control systems.

Master Quality Authenticated

Master Quality Authenticated (MQA) is a revolutionary end-to-end
technology built into every BluOS Enabled amplifier to capture and deliver MQA
music to your speakers in the purest quality. All BluOS Enabled players and
systems include a powerful decoder and audio renderer for the millions of the
MQA encoded songs, 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.

World’s Most Sophisticated Digital Room Correction

Dirac Live® and its powerful room correction
software is built in to the M17 V2i, including its own calibrated measurement
microphone and Dirac Live Pro. Advanced users can build the perfect
listening environment that corrects for both the timing and colourations in
sound, including the ability to create custom target curves for room response
and the option to choose from a variety of third-party calibrated microphones.

the advanced operating system and music management software shared with NAD’s
sister brand Bluesound, is included in the M17 V2i. When connected to the
