Sharon, MA–NAD Electronics will unveil five significant new componentsT 785, T 775, T 765, and T 755 AV Receivers, as well as the T 175 Preamp-Tuner-Processor at CEDIA EXPO in Denver next month.
NAD has never been afraid to skip the heavily hyped, me-too features and concentrate on functions and technologies that really make the difference in sound and in picture, said NAD director of product development, Greg Stidsen. So these new models are classic NAD. Instead of incorporating brochure-friendly video processing, or succumbing to the lure of the wattage wars, weve focused on meaningful goals: real-world sonics and power; pristine, non-degraded video, and genuinely ergonomic design and forward-thinking features like our uniquely, proprietarily enhanced Audyssey set-up and room-correction automation.
While all five new NADs include HDMI v1.3 inputs and switching, they eschew the chip-based video-DSP upscaling. The T785, T775, and T175 pre-pro, with four HDMI inputs each, perform high-quality HDMI cross-conversion, delivering all analog-video inputs (composite, S-, or component video) to HDMI with full quality. They also deliver NADs extensive new on-screen menu/display system via all video outputs including HDMI, permitting a single-cable link to the video display. With three HDMI ins each the T 765 and T 755 provide straightforward HDMI switching (video-only), without display-on-HDMI capability, but like their more costly siblings also perform video transcoding so that signals from any analog-video input (composite, S-, or component) are always present at any of these analog outputs.
All five models route incoming HDMI signals in their original resolution, up to and including 1080p, while the three upper models also accept digital-audio via HDMI, simplifying hookup. NAD’s pure and simple approach avoids the multiple video scaling/processing stages the company says that can actually degrade video performance.
All five of new components incorporate Audyssey Auto Calibration, a simple, sophisticated system that balances and adjusts a multi-channel speaker system using the small, calibrated microphone included with each unit. Audyssey automatically detects speakers, chooses the ideal crossovers, verifies speaker phase and adjusts levels/delays. The T 785 and T 775 receivers, and T 175 pre-pro further add Audysseys MultEQ XT Room Correction. MultEQ XT exploits proprietary time-domain digital signal processing to reduce the impact of room acoustics upon sonic accuracy, with a truly unique ability to yield a family sized sweet-spot, and to accomplish real gains in accuracy.
NAD also collaborated with Audyssey to develop proprietary target curves that yield real-world response that reflect NADs commitment to music first, and genuinely accurate reproduction. The same three models also offer support to Audyssey MultEQ XT Pro the T 785 and T 775 are the first receivers to do so. Using MultEQ XT Pro software and the added processing power of a laptop computer, the custom installer/system-designer can derive even more accurate and considerably more extensive room corrections, uploading the resulting results to the T 175, T 785 or T 775, whose Audyssey processor will implement them.
The NAD T 785, T 775, and T 765 AVRs, and the T 175 pre-proshare an entirely new electro-mechanical configuration. This places important circuitry on five fully independent, modular circuit cards, including separate cards for digital audio and HDMI, component video, analog video, and 2-channel, and multichannel analog audio.
The new receivers, like every NAD design, guarantee power production under worst-case conditions: actual 4 and 8 loads, driven full bandwidth from the deepest bass to the highest overtones (20 Hz to 20 kHz), with all channels loaded and stressed simultaneously, and performing at a stated, very low (0.05%) distortion level.
