NAD Introduces Four New A/V Receivers with Improved Performance and Features

The T 773, T 763, T 753 and T 743 offer more power, upgradeability and connectivity options to ensure greater custom integration simplicity.

NAD, the highly regarded manufacturer of high -performance audio components, introduces four new A/V Receivers, the T 773, T 763, T 753 and T743 A/V Receivers during CEDIA 2003 in Indianapolis today.


Incorporating NAD's "Music First" philosophy as the cornerstone to their ambitious design goals, three A/V receivers boast major improvements over current models with the incorporation of the exclusive PowerDrive™ amplifier technology and upgradability in two models as well as increased power and performance throughout the line.

Each model is a step up from previous models offering a significantly greater value. For instance, the T 743 offers many of the connectivity features only available in last year's T 752, which retailed for a much higher cost than the new T 743. The T 753 is significantly improved over its predecessor the T 752. It incorporates Zone 2 output allowing for independent source and volume control with the supplied ZR -1 remote. Additionally, the T 753 now features a sixth channel of amplification (6 x70W) making this the perfect solution for a self amplified DTS EX or Dolby Digital EX home theater system. This makes way for two entirely new products with the T 763 and T 773 offering more features and power than any other A/V receiver from NAD.

The new top -of -the -line model, the T 773 is the manufacturer's first A/V Receiver to include 7 -channels of internal amplification, delivering our most powerful A/V Receiver to date. This new model provides 110wpc of continuous power with all seven (7) channels driven simultaneously at rated distortion into 4 or 8 ohms. The T 763 and T 753 are equipped with six channels of amplification for rated continuous power of 100wpc and 70 wpc, respectively. The T 743 is perfect solution for 5.1 systems delivering 50wpc (x5) where only a 5 -channel home theater is desired.

The T 773, the T763 and T 753 offer the widest array of surround formats with Dolby Digital, Dolby Digital EX, DTS, DTS ES, DTS NEO:6 decoding along with 7.1 Matrix, Dolby ProLogic II and the proprietary NAD EARS circuitry for creating natural surround sound from any format input, 7.1, 6.1, 5.1 and 2.0 stereo, digital or analog. Also included is a "Stereo Enhanced" mode that uses no processing, but allows the stereo signal to be sent to any or all of the selected 7.1 channels depending on listener preference. Of course, there is an analog bypass mode for stereo purists! Surround processing is automatically detected via the digital inputs, and the most appropriate decoding format 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 capabilities. The EARS (Enhanced Ambience Recovery System) circuitry uses DSP technology to extract the natural ambience in a stereo recording and redirect it to the surround channels, creating a warm natural reverberant effect without any artificiality.

The T 773 and T 763 are upgradeable via an RS -232 port and now offer that extra degree of "future proof" operation via software upgradeability. All models include a separate 7.1 analog input for analog multi -channel sources like DVD -Audio.

NAD has always been very conservative when quoting output power ratings, preferring to state the guaranteed minimum rather than the optimistic FTC power specs that is stated by most competitors. NAD chooses the far stricter and more conservative Full Disclosure Power rating, with all channels driven simultaneously, at any frequency 20Hz to 20kHz, with less than 0.08% THD at 8 and 4 ohms. Finally, in what we consider to be most representative of real world performance, we include Dynamic Power at 8 ohms, 4 ohms, and 2 ohms!

The exclusive NAD PowerDrive™ technology, incorporated in the T 773, T 763 and T 753, automatically adjusts the amplifier's power supply settings to meet the needs of the loudspeaker, resulting in e remarkably dynamic and distortion -free performance, even with demanding 4 -ohm loads. 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.

All the new A/V Receivers are extremely flexible, providing a full suite of inputs and outputs to accommodate all the latest digital audio and video products.

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. In the case of the T 763, T 753 and T 743 their internal amplifiers can be used for 6/5 channels of amplification and an additional amplifier can be added for the extra channel(s). There are two subwoofer outputs as well to support the most ambitious Home Theater setups.

With all four A/V Receivers, NAD has made it easy to add stereo speakers to an adjacent room for shared source music listening. 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.

Each model provides three 12 -volt triggers to automatically switch remote zone amplifiers on and off. Custom friendly features like discrete On and Off codes, direct access to inputs and FM station presets facilitate their seamless integration into elaborate remote control systems.

The three 12V output triggers also allow for automatically switching remote zone components such as amplifiers, video projectors and screens (even lights) on and off. IR inputs and output make it easy to integrate with popular control systems like Aegis, Xantech and Niles. Discrete ON and OFF commands, and direct access to inputs and FM presets make it possible to integrate with popular remote keypad systems.

NAD took special measures to ensure that operation of all the new receivers was logical and straightforward. Initial system setup is accomplished using the simple On Screen Display (OSD) on any video monitor system. Five A/V Presets can be stored for instant recall with unique speaker configuration, level, distance, surround mode and tone control settings for instant recall. This allows a user to set up one type of playback for multi -channel music and a completely different setup for movie soundtracks. Channel level settings for Sub, Center, and Surround can be adjusted on the fly via the supplied HTR -2 Remote Control without entering any setup menus for maximum convenience.

The FM tuner includes 30 favorite station presets that can be custom named, or if the station supports the Radio Data System (RDS) an automatic stream of information about the station and music being played is displayed.

The HTR -2 Home Theater Remote can operate up to 8 different devices. The buttons feature illumination with adjustable time -out for easy operation in low light environments. Remote commands for products not already included in the HTR -2's memory can be easily learned by the HTR -2. Plus the HTR -2's Macro function allows up to sixty -four individual commands to be triggered by any of 36 assignable keys. Layout is logical and intuitive enough to operate most functions by tactile feel alone.

The T 773 and T763 will be available in late October at an MSRP of $1799 and $1399 respectively. The T 753 and T743 will be available in late November at an MSRP of $999 and $699 respectively. These A/V Receivers will be on display with NAD's other new products in Booth # 308 in the Indianapolis Convention Center during CEDIA EXPO 2003.
