Modular Design Construction
NAD has developed a unique new architecture that keeps pace with the fast
changing world of digital formats by allowing connectivity and feature upgrades
as new technology becomes available. This prevents premature obsolescence by
keeping pace with the latest developments in high performance audio and video
formats. Dealer installed hardware and software can add new connectivity and
features at a future date, allowing your T 775 HD2 to grow as your needs and
tastes develop. Most AV receivers require complete replacement with a new model
to get the latest features. With NAD you only replace the module you want to
upgrade – not the entire AV receiver!
Audio Performance
Today’s advanced Surround Sound receivers require quality in the digital decoding
stages, the video processing section, and in the power amplifier design for the
best overall performance. The T 775 HD2 is an excellent example of the NAD
Design Team’s expertise in all three areas. Not only that, but we have made many
ergonomic refinements to simplify operation and make it more enjoyable to get all
the performance from this magnificently capable receiver.
Using the latest Dual Core Floating Point DSP technology, NAD was able to include
the newest surround formats from Dolby and DTS, as well as NAD’s own highly
regarded music surround mode - EARS. The EARS circuit (Enhanced Ambient
Recovery System) is now optimized for 7-channel surround. Unlike the typical
artificially enhanced DSP modes like ‘Club’, ‘Stadium’, and ‘Church’, EARS uses
DSP technology to extract the natural ambience of the recording. This is redirected
to the surround channels to create natural surround sound from any 2-channel
source. This induces a warm natural reverberant effect without the hollow ‘BOING’
of artificial reverb.
The surround mode of the source material is automatically detected via the
digital inputs of the T 775 HD2, 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 carefully selected for their
performance capabilities.
NAD’s reputation for producing power amplifiers that are both potent and musical
is upheld in fine manner with the T 775 HD2. Boasting a minimum of 100 watts
continuous power per channel, the T 775 HD2 can fill even large rooms to lifelike
sound levels. NAD’s exclusive PowerDriveTM amplifier technology automatically
adjusts the power supply settings of the amplifier to the needs of the loudspeaker.
This ensures remarkably dynamic and distortion-free performance with any type
of loudspeaker, even demanding 4 ohm designs. Many less advanced receivers
prohibit the use of 4 ohm speakers. With PowerDriveTM, the performance is always
optimized for the actual operating condition and as a result, the amplifier exhibits
very low distortion and good current drive in the real world. Explosive musical
dynamics are effortlessly handled without added distortion.
Credit for the sound of NAD’s components rests squarely with our unique design
approach and our experienced and very talented design team. Most companies
design their products to a technical specification and a price point. While this
sounds logical enough, it does not address the way the product will actually be
used by the eventual owner. You don’t listen to specifications, you listen to music
and sound. While NAD products exhibit excellent technical measurements, we
have relied on our own ears and listening experience to determine the final design
of our products. Because of our unique design approach, NAD’s sound is simply
more real sounding, adding enjoyment and excitement to your favourite films and
music recordings.
Video Performance
Employing the very latest generation of advanced HDMI 1.4a Receiver and
Transmitter chips in the VM 100 3D video module ensures compatibility with the
T 775 HD2 AV Surround Sound Receiver
broad range of 3D and HD digital video sources and displays available today. NAD
engineers have utilized a powerful FPGA with our own custom software to process
the video signal, enabling the conversion of analogue video to digital video and
allowing a single cable connection to your TV for all sources while maintaining the
source’s native resolution. Interlaced video is converted to progressive scan over
HDMI allowing for complete compatibility with the latest HD TVs. NAD’s clear
and simple On Screen Display is available on all Video Monitor outputs. All audio
formats, including High Bit Rate audio from Blu-ray players, are supported by the
VM 100 3D Video Module.
The T 775 HD2 has all the flexibility required to serve as the command centre for even
the most sophisticated Home Theatre and multi-room systems. A full suite of video
switching caters to all the popular video formats (HDMI, Component Video, S-Video,
and Composite Video). Digital inputs (including a handy front panel input) and outputs
are available in both coaxial and optical formats to make it easy to attach all your digital
sources for playback and recording. Digital Inputs are converted to analogue for use
in Zone 2 and you can choose to convert unused audio/video outputs for Zone 3 and
Zone 4 use with independent source selection and volume control.
With the T 775 HD2, NAD has made it easy to add more speakers for listening to
music in additional rooms or ‘zones’. A second pair of speakers can simply be added
to the front channel amplifiers and switched on or off from the remote control or
front panel switch. More elaborate systems can also be created using the Zone 2,
3 and 4 outputs to add amplifiers and speakers with the benefit of independent
source selection and volume control. Furthermore, the Back Surround Amplifiers can
be assigned to any of these zones, allowing for a simultaneous 5.1 Home Theatre
and a powered second zone. A separate second zone remote is included.
There are also 12 volt triggers to automatically switch remote zone amplifiers on
and off, and even an RS-232 data port for connection to highly advanced automated
control systems. Thoughtful features like discrete On and Off codes, direct access
to inputs and FM station presets facilitates the integration of the T 775 HD2 into
elaborate remote control systems.
An analogue 7.1 input is also provided for attaching a DVD-Audio player or any
other yet to be developed surround decoder, ensuring that the T 775 HD2 does
not become obsolete anytime soon. Preamp outputs allow the addition of more
powerful amplifier channels.
Luxurious Simplicity
All the capability and flexibility in the world is quite useless if the receiver becomes
too complicated to be operated by every member of the family. NAD has taken
special measures to make operation of the T 775 HD2 as logical and straightforward
as possible.
Initial system setup is best accomplished using your television monitor and the clear
and simple On Screen Display (OSD), which can be configured to also give status
updates as settings are changed in everyday use. Once the T 775 HD2 is informed
of your specific system setup, all settings are stored in a non-volatile memory making
this a one time task. The informative front panel display indicates complete
information about the source being listened to or watched including selected
surround mode and volume setting. The front panel display can be easily customized
by renaming inputs and even determining what information you prefer to be
displayed and when to display it.
Audyssey Auto Calibration is available using the supplied calibrated microphone.
Simply place the microphone in the listening position and select Audyssey autocalibration and the system automatically detects which speaker is connected,
chooses the ideal crossover point to the subwoofer, checks speaker phasing, and
adjusts the levels and delays. These adjustments are made to a level of accuracy that
it would be difficult to duplicate by ear alone.
Audyssey MultEQ XT is the latest in digital sophistication, allowing for improved
frequency response in a large ‘family-sized’ sweet spot. Using the calibration
microphone to ‘hear’ your room, a series of test tones measure the speakers’
response and the room’s distorting echoes independently, and then calculates an
ideal response that minimizes the effects of the room’s echoes. While this sounds
simple, the digital technology that is required for this level of performance would
have cost many thousands of dollars just a few short years ago. But the electronic
technology is only half the story, since an advanced knowledge of acoustics is also
required to get good results from such a system. Working closely with Audyssey,
NAD’s acoustic engineers developed the final response curves that reflect our own
performance values.
Audyssey Dynamic Volume and Dynamic EQ work together to address the problem
of large jumps in volume when switching between different TV channels or when
advertisements are inserted into the program. There is also an effect caused by our
ears’ different sensation of low and high frequencies at different listening levels: as
the volume is reduced our sensation of bass frequencies is reduced more than the
midrange frequencies.
The T 775 HD2 tuner section can store a mix of your 40 favourite AM, FM and
XM (or DAB/DAB+) stations for immediate recall. These presets can be custom
named. And if your selected FM station supports the Radio Data System (RDS), it will
automatically stream information about the station and music being played. We also
include a ‘Digital Broadcast Ready’ socket on the rear panel for adding outboard DAB
or XM modules. All the control software for these formats is included, just plug in the
module and start enjoying the clear sound and expansive content selection available
with Digital Radio Broadcast.
Five independent ‘Audio Video Presets’ can store speaker level and tone control
settings for instant recall, making it easy to custom tailor your system for different
types of program material. Encoded surround modes like Dolby Digital and DTS are
automatically selected if the program is so encoded. The T 775 HD2 also remembers
your last used settings when switched in and out of Standby mode.
The T 775 HD2 offers remarkable performance and flexibility in a compact and
simple to operate package. This multi-channel powerhouse will bring your
favourite music and movies to life in your home entertainment room with an
absolute minimum of fuss and a maximum of pure enjoyment.
