NAD M32 Masters DirectDigital Integrated Amp / DAC

Description

As the culmination of 45 years of experience in home audio
design, the NAD M32 DirectDigital^™ DAC Amplifier redefines the
modern audio component system. Combining all pre-amplification and power
amplification functions into a single amplifying stage, the M32 is the ultimate
amp for your home entertainment system. Thanks to NAD’s MDC technology, the M32
is ready for all future upgrades, ensuring that your system will never fall
behind the times. By adding the BluOS MDC Module, the M32 becomes a member of
the BluOS^® ecosystem, thus opening the doors to your music
library regardless of whether it’s stored on hard drives or the cloud. By
minimizing both noise and distortion, the M32 allows you to hear your favorite
songs in rich, clear detail, giving you a music listening experience unlike any
other.

An Elegant, Top-of-the-line, BluOS Ready Integrated
Amplifier

Redefining the Integrated Amp

The traditional integrated amp included the preamp control
centre with the power amp in a single chassis. The downside of this was the
reduced flexibility and possible interference by the high voltage power
circuits to the highly sensitive preamp stages caused by cramming everything
into one box. In the new digital age, these limitations disappear. The signal
can stay in the digital domain right up to the speaker outputs, making the M32
preamp impervious to interference from the power stage. Concerns about limited
flexibility are erased by NAD’s innovative Modular Design Construction (MDC),
which allows a greater density of inputs as well as the flexibility to upgrade
complete circuits as future technologies unfold.

Modular Design Offers Maximum Flexibility

By placing inputs and associated circuitry on uniform
upgradeable modules, the M32 can be custom tailored to cater to your exact
requirements. There are a total of four MDC slots, with three being available
for expansion. The preinstalled module is the SPDIF Module, including AES/EBU,
2 x Coax and 2 x Optical, all 24/192 capable. Additionally there is a USB B
port for connecting computers as well.

The Preamp is Replaced By Software

When it comes to the M32 we have combined all preamp and
power amp functions into a single amplifying stage controlled by software.
Highly advanced mathematics determines all control functions including volume
and filters. This produces a dramatic reduction in noise and distortion,
bringing you much closer to both the music and the performers. Traditional
volume controls that change the gain in an active analogue circuit cannot
approach the transparency of the M32. It also allows ‘perfect’ tone controls
that only change tone, without adding phase shift or distortion. You can also
easily bi-wire or add a subwoofer(s) with the built-in electronic crossover.

Ready For Hi-Res Audio

By simply adding the optional BluOS MDC Module, the M32
becomes part of the BluOS^® wireless multi-room music ecosystem.
Unlike UPnP or AirPlay^® which rely on middleware to translate
between different platforms; BluOS is a true operating system unlimited by
reliance on middleware or computers.
As the leader in high-resolution network audio, BluOS is a
complete music management system that brings all your music together, whether
it is on hard drives or the cloud, into one easy-to-use control app for
smartphones, tablets and laptops. It is also a wireless multi-room system fully
compatible with the amazingly affordable Bluesound wireless speakers and
digital music players.

Phono and Headphones Are Not Forgotten

The M32 also has 2 x Line Inputs and a MM Phono Input that
sounds incredible with vinyl. Accurate RIAA equalization, a clever phase
cancelling infrasonic filter, and a huge overload margin combine to bring out
the best in your LPs. Furthermore, if you are a headphone enthusiast you’ll be
thrilled at the sound of our discrete headphone amplifier, which is able to drive
even planar and high impedance studio cans. With high voltage and low output
impedance, your headphones will sound their best.

DirectDigital^™ Defined

With 2 x 150W power on tap, the M32 can make almost any
speaker sing. The M32 has virtually no distortion, and a damping factor that is
off the chart. This is all due to the innovative DirectDigital^™ Feedback
Amplifier built under license from Cambridge Silicon Radio (CSR), which uses a
form of digital error correction that is incredibly fast and accurate. This is
a true digital amp (not just Class D) that is computer controlled and amplifies
entirely in the digital domain, converting to analogue at the speaker
terminals. This gives it the shortest signal path in NAD’s history.

Modern and Fresh

The all-alloy casework is elegant and practical. The single
control knob for volume is supplemented by a TFT touchscreen display, which
replaces a multitude of mechanical switches and expands the range of
adjustments possible with detailed graphical readouts (IR remote is also
included). Because the controls are all software defined, we can add new
controls and features by simply upgrading to new firmware. This is quite
revolutionary and works hand-in-hand with MDC to create a future-proof digital
music player. Rigid panels with magnetic iso-point feet provide a solid
foundation for the multi-layer circuit boards and intricate internal
construction. The M32 is a completely modern and fresh take on the traditional
stereo amplifier, with features and performance from the future.

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.
