Details The NAD T755 is heir to many generations of award winning NAD designs. This exceptional pedigree is evident in both the look and the feel of the T755, and it is unmistakable the moment you listen. It is NADs 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. NADs Music First philosophy dictates that we endow our Surround Sound 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 Surround Sound components primarily from a content point of view, with sound quality far down the list of priorities. Yet the T755 is second to none in terms of flexibility and up-to-theminute digital technology. Full Disclosure Power Ratings Inflated power specifications have been used to sell receivers as long as there have been receivers to sell. But not at NAD. Instead, we encourage our customers take a clear-eyed look at the real issues. Receivers dont make music and filmsound by driving laboratory test-loads, they do it by driving loudspeakers. And loudspeakers, whether labeled 8 or 4 in nominal impedance, are far more challenging. A speaker
that looks like an 8 resistor at some frequencies will show 4 at others, and often, 3 or even 2 at still others. Furthermore, actual loudspeaker loads are far more complex than simple test resistors. What does all this mean? Simply, that power on paper is but a poor predictor of how loud, how dynamic, how musical. Nevertheless, in a competitive market comparisons will be made. But when you make them, read the fine printall of it. At NAD we test under the most demanding, worst-case conditions, reporting the minimum power output we achieve at any frequency within human audibility (full audible bandwidth of 20Hz-20kHz), and with all channels driven and fully stressed simultaneously at clearly specified, vanishingly low distortion. Many competitors do not: they often quote single-frequency power (1 kHz) reflecting at most one associated channel (maximum 2 channels) dominating the receivers power supplyoften under a variety of deceptive power headings. And if distortion is stated at all its usually at quite high levels: 0.5 percent, 1 percentin one case, 10 percent!its easy to print big numbers that simply do not tell the true story. The bottom line: dont be fooled by specs; let your ears be the judge. PowerDrive This keystone of the NAD receivers amp-section design underpins the unique dynamic potential of every model. PowerDrives foundation is a dual-rail power supply that delivers enhanced internal voltage levels whenever unusual demands approach: dynamic peaks, big musical transients, deep-bass excursions that drive a loudspeaker into its most power-hungry impedance range. Its a little like the kickdown of a sophisticated automatic transmissionone that happens in 1/50,000th of a second. PowerDrive is one big reason why NAD AV receivers do not exhibit the dynamic compression, flattened imaging, and even tinges of harshness audiophiles so often decry as receiver sound. And PowerDrive not only makes NAD receivers sound better, it makes them cooler running, more efficient, and more reliable as well. Performance Todays 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 T755 is an excellent example of the NAD Design Teams 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 this magnificent receiver is capable of delivering. Using the latest 32 bit Dual Core Floating Point DSP technology, NAD was able to include the most popular surround formats from Dolby and DTS, as well as including NADs own highly regarded music surround mode; EARS. 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 artificial BOING of artificial reverb. The surround mode of the source material is automatically detected via the digital inputs of the T755, and the highest or most advanced form of decoding is switched in. Conversion of the encoded digital bitstream is performed with high resolution and

extremely linear Burr-Brown 24 bit/192kHz D/A Converters carefully selected for their performance capabilities. NADs reputation for producing power amplifiers that are both potent and musical is upheld in fine manner with the T755. Boasting a minimum of 80 watts continuous power per channel, the T755 can easily fill a room with lifelike sound levels. Credit for the sound of NADs 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 dont 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, NADs sound is simply more real sounding, adding enjoyment and excitement to your favorite films and music recordings. Flexibility The T755 has all the flexibility required to serve as the command center for even the most sophisticated Home Theater and multiroom 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. With the T755, 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 outputs 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 facilitate the integration of the T755 into elaborate remote control systems. An analog 7.1 input is also provided for attaching a DVD-Audio player or any other yet to be developed surround decoder, making sure the T755 does not become obsolete anytime soon. Preamp outputs allow the addition of more powerful amplifier channels. The T755 includes a data jack specifically designed to control an iPod with the addition of NADs optional iPod Dock accessory. This allows the iPods 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.

All input circuitry is contained on 5 easily removable plug in cards. Although this construction technique is more costly to implement, it offers several important advantages. 1) Speed to market for new technology. 2) Upgrade for older units 3) Simple field service. 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 T755 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 T755 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 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 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 it would be difficult to duplicate by ear alone. The FM tuner includes 30 favorite 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. We also include a Digital Broadcast Ready socket on the rear panel for adding an outboard XM module. All the control software 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 Custom Presets can store unique listening modes, DSP options, tone, speakers and display 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. The T755 also remembers your last used settings when switched in and out of Standby mode. The included HTR 3 remote handset is itself an engineering tour-deforce. Able to control up to 8 different components, the device key illuminates to clearly shows what device is being controlled. It has illuminated buttons for easy operation in low light environments, and the length of time the illumination is on can easily be adjusted. Remote commands for products not already included in the HTR 3s memory can be easily taught to the HTR 3. And the HTR 3s 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 3s Macro function. Summary The T755 offers remarkable performance and flexibility in a compact and simple to operate package. This multi-channel powerhouse will bring your favorite music and movies to life in your home entertainment room with an absolute minimum of fuss and a maximum of pure enjoyment.
