Today’s 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 T775 is an excellent example of the NAD Design Team’s 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 expected surround formats from Dolby and DTS, as well as including NAD’s 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 T775, 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. The T775 uses five two-channel DACs rather than the usual single 8 channel DAC favored by many of today’s surround sound receivers. We have found that the sonic performance of the two-channel DACs used in a dual differential mode, is well worth the extra cost of this configuration.

The T775 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 T775, NAD has made it easy to add more speakers for listening to music in an additional room or “zone”. 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, 3 and 4 outputs to add additional amplifiers and speakers with the added benefit of independent source selection and volume control. For added flexibility the back surround amplifier channels can be assigned to Zone 2 if the main zone is 5.1. A separate second zone remote is included.

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.
