NAD AV RECEIVER UPDATE New models T785, T775 and T175
New models T785, T775 and T175
New Technology and Key Features
Modular Design Concept
All the input circuitry is contained on 5 easily removable plug-in cards. They are
1. Digital Audio and HDMI
2. Component Video
3. Analog Video
4. Analog Audio (2 Channel)
5. Analog Audio (Multi-channel)
Although this construction technique is more costly to implement, it offers several important
• Speed to market for new technology.
• Upgrade for older units
• Simple field service
HDMI and Format Conversion
We are using the very latest V1.3 HDMI chips from Analog Devices. NAD has decided to forego
video processing in order to allow the highest possible video quality. This means that we only
change formats, we do not add any artificial artifacts to the signal – pure and simple. All input
resolutions (480, 576, 720, and 1080) are supported at the output. All analog formats are cross
converted between Composite, S-Video and Component. These analog inputs are also upconverted to HDMI output. HDMI inputs are not allowed to be output as analog signals due to
copy protection restrictions. Output resolution always matches input resolution – perfectly.
Audyssey MultEQ XT
Audyssey MultEQ XT combines an “auto setup” feature with “room correction”. A calibrated
microphone is supplied and is used in combination with a special set of test tones to
automatically set speaker configuration, subwoofer crossover frequency, speaker level and
speaker distance. The user interface has a ‘wizard’ to easily walk the user through the
calibration procedure.
The room correction feature uses multiple microphone positions and a unique (and patented)
algorithm to create a “family sized” sweet spot where room reflections (standing waves) are
reduced or eliminated. NAD has worked very closely with Audyssey to create a unique “NAD
Target Curve”. The target curve represents the final frequency/time response at the listening
Made for iPod Connection
These new AVR’s will include a data jack specifically designed to control the iPod. Adding
NAD’s iPod Dock accessory will allow the iPod’s meta-data to be displayed on the OSD and be
controlled using the NAD remote control. Audio and Video connections and iPod recharging are
also featured in the iPod Dock.
DAB Ready (XM Ready in 120V Countries)
This unique NAD feature allows the addition of DAB radio now, or in the future. Simply attach
the optional DB 1 external DAB Module to the AVR. The AVR supplies power and control to the
DB 1, and the DB 1 sends DAB audio, in digital format, to be decoded by the superior DA
conversion and amplification of the NAD AVR.
Improved User Interface
We have made vast improvements over the already “best in class” UIF of the T7x3 AVR’s.
Unprecedented flexibility and simplicity add up to true ease-of-use. 10 inputs (including Tuner
which has 3 options) can be configured with any combination of audio and video, analog and
digital sources, and renamed to match the source. Unused inputs can be hidden to avoid the
confusion of the “empty” input. Navigation is fast and crisp, and there are many choices for how
the status information is displayed. This is true “mass customization” – every individual will
have a unique simple setup!
4 Zone Capability
In addition to the main zone and second AV zone, we have added the flexibility to change the
Tape Outputs to be third and fourth Audio Zones with independent source and volume
capability. There is complete flexibility in setting up these outputs.
Amplifier Channel Assign-ability
The Back Surround amplifier channels can be reassigned to Zone 2, 3, or 4, or redirected to the
Front Left and Right channels to allow bi-amping of the front speakers. This is easily
accomplished in the User Interface.
More Power, Less Distortion
A new circuit layout with input from BEE has resulted in more efficiency and less distortion than
any other AVR in NAD history. Glass epoxy PCBs, Surface Mount Devices and lead-free solder
all contribute to this exceptional performance.
New Fan Circuit
Similar to the Masters Series M25 circuit, the new AVRs use fans that are thermostatically
controlled but are silenced during quiet scenes or pianissimo passages. Additionally, the fans
are now rubber isolated and are mounted on a bottom accessible panel. In combination with
NAD’s famous ‘wave pattern’ heat sinks these AVR’s, when properly installed, can run for hours
under the most severe operating conditions. Our competitors can barely last a few minutes
under the same operating conditions!
New Remote
The T175 and T785 get a new version of the M15’s HTRM called the HTRC 1.
