The NAD T 773 is heir to many generations of award
winning NAD designs. This exceptional pedigree is
evident in both the look and the feel of the T 773, and it is
unmistakable the moment you listen. It is NAD’s insistence
on creating products with remarkable sound quality at
sensible prices that has made NAD the first choice among
the most knowledgeable listeners from around the world.
NAD’s “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 773 is second to none in
terms of flexibility and up-to-the-minute digital technology.
Today’s advanced surround sound receivers require
quality in both the digital decoding stages and the
analogue amplifying stages for the best overall
performance. The T 773 is an excellent example of the
NAD Design Team’s expertise in both areas.
Using the latest high speed DSP technology, NAD
was able to include the newest surround formats from
Dolby and DTS, as well as including NAD’s own highly
regarded music surround mode, the EARS (Enhanced
Ambient Recovery Circuit) circuit. Unlike the typical
artificially enhanced DSP modes like “Club”, “Stadium”,
and “Church”, EARS uses DSP technology to extract the
natural ambience to create surround sound from any 2
channel source inducing a warm natural reverberant effect
without the artificial “BOING”. Surround processing is
automatically detected via the digital inputs of the T 773,
and the “highest” or most advanced form of decoding is
switched in. Conversion of the decoded digital bitstream
is performed with high resolution and extremely linear
D/A Converters carefully selected for their performance
NAD’s reputation for producing power amplifiers that are both
potent and musical is upheld in fine manner with the T 773.
Boasting a minimum of 110 watts continuous power per channel,
the T 773 can fill even very large rooms to lifelike sound levels.
NAD’s exclusive PowerDrive amplifier technology automatically
adjusts the power supply settings of the amplifier to the needs of
the loudspeaker. This ensures remarkably dynamic and distortionfree performance with any type of loudspeaker, even demanding 4
ohm designs. Many less advanced receivers resort to performance
robbing protection resistors to allow the use of 4 ohm speakers.
With PowerDrive, 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.
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.
The T 773 has all the flexibility required to serve as the command
center for even the most sophisticated Home Theatre systems. A
full suite of video switching caters to all the popular video formats
(Component Video, S-Video, and Composite Video). Digital inputs
and outputs are available in both coaxial and optical formats to make
it easy to attach all your digital sources for playback and recording.
With the T 773, 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 Multi-Source
output to add additional amplifiers and speakers with the added
benefit of independent source selection and volume control. 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 773 into elaborate remote control
An analogue 7.1 input is also provided for attaching a DVD-Audio
player or any other yet to be developed surround decoder, making
sure the T 773 does not become obsolete anytime soon. Preamp
outputs and main amp inputs, a long standing NAD feature, allow
the addition of more powerful amplifier channels and/or the
reconfiguring of amplifier channels. (for example adding a more
powerful external amplifier to the front channels, and using the
onboard front channel amp or back surround channels amps to
power a second music zone from the Multi-Source output.)
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 773 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 773 is informed of your
specific system set-up, 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 FM tuner includes 30 favourite station presets
that can be custom named, or if the station supports the Radio Data
System (RDS), it will automatically stream information about the
station and music being played.
Five independent “Scenario 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 773 also remembers
your last used settings when switched in and out of Standby mode.
The included HTR-2 remote handset is a model type that is
replacing the typical remotes found for TVs, VCR’s DVD players
etc... It has illuminated buttons for easy operation in low light
environments. Remote commands for products not already
included in the HTR-2’s memory can be easily “taught” to the
HTR-2. And the HTR-2’s Macro function allows up to 64 individual
commands to be triggered by the pressing just two keys. With
this feature, all of the commands required for watching a DVD,
for example, are executed automatically by the HTR-2’s Macro
The T 773 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.
