TURES
‘Music First’ philosophy dictates that we endow our Audio Video products with the same warm, involving sound quality that makes music
listening so rewarding with our stereo components. This stands in stark contrast to our competitors who view Audio Video components primarily
from a ‘content’ point-of-view, with sound quality far down the list of priorities. Yet the T 765 is second to none in terms of flexibility and up-tothe-minute digital technology.

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 765 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 765 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.
The AM 100 Audio Module uses 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 765, 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 765. Boasting a minimum of 80 watts
continuous power per channel, the T 765 can easily fill a room with 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 Receiver and Transmitter
chips in the VM 100 video module ensures compatibility with the broad range
of 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
T 765 AV Surround Sound Receiver
On Screen Display is available on all Video Monitor outputs, and all audio formats
including High Bit Rate audio from Blu-ray players, are supported by the VM 100.
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 765 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 765 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 have displayed and when to
display it.
Automatic Audio Setup is available using the supplied calibrated microphone.
Simply place the microphone in the listening position and select Audyssey Setup
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 would be difficult to
duplicate by ear alone.
The T 765 tuner section can store a mix of your 40 favourite AM, FM and XM (or
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 765 also remembers your
last used settings when switched in and out of Standby mode.
The included HTR 3 remote handset is in itself an engineering tour de force. Able to
control up to eight different components, the device key illuminates to clearly show
what device is being controlled. It has illuminated buttons for easy operation in a
low light environment, and the length of time the buttons are illuminated can be
easily adjusted. Remote commands for products not already included in the HTR 3’s
memory can be easily ‘taught’ to the HTR 3. And the HTR 3’s Macro function allows
up to 64 individual commands to be triggered by pressing just two keys. With this
feature, all of the commands required for watching a DVD, for example, are executed
automatically by the HTR 3’s Macro function.
Summary
The T 765 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.
