T 785 AV Surround Sound Receiver
Video Performance
The T 785 features NAD’s newly developed HDMI repeater featuring Sigma’s
VXP Image Processor. Both analogue and digital video sources can be selectively
processed using Sigma’s advanced VXP algorithms. This is the best performing
image processing engine we could find, and the T 785 is the only AVR on the
market featuring this advanced technology usually reserved for high end preamp
processors and HT projectors.
The new VXP video board features video conversion to resolutions as high as
1080p and supports all SD and HD formats up to 2048 x 2048 pixels. Motion
adaptive de-interlacing with edge interpolation eliminates the jagged edge effects
common in lesser image processors. Film mode detection with output cadence
generation endows the video picture with a film-like smoothness of motion.
The programmable scaling engine also allows for aspect ratio conversion to
perfectly match the video source with the video display. Advanced noise reduction
and detail enhancement improve legacy analogue video sources to near HD quality.
Flexibility
The T 785 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 785, 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 785 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 785 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 785 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 785 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 auto-
calibration 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.
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 785 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 785 also remembers your
last used settings when switched in and out of Standby mode.
