ABOUT THE T 743

Though the T 743 is among the most technically sophisticated A/V receivers, we worked hard to make it one of the most musically transparent home-theater components available as well; this is what we mean by NAD’s “Music First” design philosophy. Here are just a few examples:

NAD’s exclusive Soft Clipping™ circuitry further enhances sound quality and dynamic potential.

High-performance components used throughout the receiver’s analog audio circuits maximize quality from all sources, including multichannel analog sources such as DVD-Audio and SACD.

Preamp output (all channels) and main-amp input jacks make potential expansion as flexible as possible.

A Second set of Speaker terminals (Speakers B) for remote listening.

Gold-surfaced connectors are employed throughout to ensure maximum signal integrity.

E.A.R.S. AND DIGITAL SURROUND

A key element of the T 743’s unique musical aptitude is NAD’s proprietary Enhanced Ambience Recovery System (EARS). In sharp contrast to many “ambience-synthesis” music-surround modes, EARS exploits the T 743’s substantial DSP power to route the ambient content that is “encrypted” in virtually all natural- acoustic recordings to the appropriate main, center and surround speakers, without resorting to artificially generated reflections or regeneration. EARS’ natural ambience yields a subtle but exceptionally effective surround mode that naturally enhances the spatial presentation in a fashion suitable for serious music listening. Dolby ProLogic II Music and DTS Neo:6 Music modes can also create enjoyable experience from 2- channel sources.

On the digital side, the T 743 combines extraordinarily high-speed DSP processing employing one of the most advanced high-speed DSP “engines” available, with fully 24-bit, 96 kHz-sampling-capable D/A converters for all channels. A single, high-precision master clock synchronizes all digital circuits to eliminate the timing errors (“jitter”) that otherwise compromise sonics. The result is legitimately state-of-the-art surround decoding from Dolby Digital and DTS sources, with genuinely superior sound quality in all modes.

EASE OF USE

Despite the effort NAD has invested in the T 743 receiver’s sonic performance, we expended no less in making it powerfully easy to use. Its design is uniquely simple for so sophisticated a component, and the HTR

2universal remote control is equally understandable, as are the T 743’s own front-panel and on-screen displays. Its simple yet powerful system of “presets” permits you to fine-tune your listening setup for different conditions, sources, or listeners, and to recall these multiple parameters with a single keypress.

INTEGRATION

The T 743 receiver offers extensive, flexible system-integration options through its configurable DC trigger outputs and input, and its standard-protocol IR communications links.
