Just select the desired source – audio or video – set the volume, and hang onto
your hat as the M15 HD takes you deep into the essence of the music or movie you
are about to experience.
Our User Interface uses a clear front panel display as well as an ‘on screen display’
that provides setup information directly on your connected TV screen. This is where
the M15 HD can be customized to refl ect your specifi c needs and desires. Surround
format preferences, level matching of inputs (so there won’t be an annoying jump
in volume when you switch sources), and even the renaming of inputs can all be
set in these simple two layer menus.
ONE REMOTE
The M15 HD is supplied with the latest iteration of NAD’s renowned remote control,
the HTRM (Home Theatre Remote – Masters Series). This ‘smart’ remote can learn
the commands of any IR remote for any other component. The innovative learning
circuit can easily memorize any command (including many that other remotes fail
on), and can also memorize a sequence of commands (we call this a macro) to
simplify the operation of your entire audio video system.
We use a logical layout of keys that are supplemented by a two-line LCD display to
keep you informed of which component you are controlling and which command is
being sent. We strongly believe that this combination of keys and display creates
the easiest and most satisfying user interface of any remote control. Once familiar,
most operations can be completed using the sense of touch alone, allowing you to
stay focused on the video picture of your program. In darkened rooms, the HTRM
automatically illuminates its keys and display for easy viewing.
The HTRM also includes a PC interface for advanced programming and easy
backup or cloning of your particular HTRM setup. Simply connect via USB cable to
a computer running MS Windows and load the supplied program. Commands for
various components can be stored, and complex macros can be easily confi gured
and downloaded into the HTRM.
LUXURIOUS DESIGN
The design brief reads: “The industrial design must create a physical presence that
is powerful, dynamic, and solid, yet refi ned and elegant”. We wanted a design that
will still look fresh and new a decade from now a design with classic proportions
and understated details.
Intelligent use of aluminium extrusions, zinc castings, and heavy gauge steel results
in a chassis that is as rugged as it is handsome. Innovative use of specialized
coatings and plating results in a product that will retain its good looks for many,
many years to come.
COMPATIBLE AND UPGRADABLE—
MODULAR DESIGN CONSTRUCTION
The M15 HD interfaces perfectly with the majority of consumer audio and video
formats including the latest, HDMI. But we know that as digital technology
evolves there will probably be different requirements in the future. To remove
the ‘obsolescence factor’ we have placed all audio and video input circuitry on
individual modules that can be easily upgraded in the future if desired.
Additionally, the operating and decoding software can be upgraded via serial port
when new features and formats become available. The M15 HD has four times
the processing power of the original M15 and is using the latest ultra high speed
32-bit fl oating point DSPs for all decoding and post processing.
The M15 HD also supports NAD’s optional Dock for iPod, allowing complete
control of your iPod with your M15 HD remote control and On Screen Display.
With rear panel IR remote input and outputs, programmable 12V triggers, and an
RS-232 port, the M15 HD is highly compatible with many of the advanced control
systems such as AMX and Crestron.
THREE INDEPENDENT REMOTE ZONES
Three completely independent audio ‘zones’ are available, each with its own
remote control codes, as part of the M15 HD package. These line level outputs
have independent source and volume selection, and are ready to interface with
outboard amplifi ers and controllers to send music to other rooms in your home.
One zone also has an independent video feed. A small Zone Remote is provided
to control Zone 2. Zone 3 and 4 codes are included in the HTRM remote library.
POWER SUPPLIES
The heart of every electronic component is its power supply. Taking the raw current
from the wall socket and creating stable, clean DC voltages is crucial to obtain
the maximum performance of every circuit in the M15 HD. The M15 HD uses two
different power supply technologies to provide performance without compromise.
A very tightly regulated Switch Mode Supply provides the high current and stable
voltages required by the ultra high speed video and audio processing in the new
HD circuits. The audio circuits utilize a linear supply fed by a custom designed
C-Core Transformer. This feeds into independent rectifi ers and multi-stage
regulators to obtain pure and stable voltages for each individual audio circuit.
By keeping analogue and digital completely separate, any possible cross
contamination is prevented.
AUDIO PERFORMANCE FEATURES
Tone controls, AV presets, and direct access to sub, centre, and surround levels
allow unprecedented control of the sound fi eld. Centre channel tone control
operates in the ‘presence’ region of the human voice to improve the intelligibility
of dialogue. This is especially effective for many Dolby processed recordings. AV
Presets take a ‘snapshot’ of any combination of speaker selection, level, and
crossover frequency, to be recalled with just a couple of button presses of the
remote control. You could, for example, have different setups for music and movies,
or even settings for different types of music or different surround modes. Direct
access to the subwoofer, centre, and surround speaker levels, without calling up
menus, allow for ‘on-the-fl y’ adjustments without interrupting the video program.
