Modular Design Construction (MDC)

With MDC all major digital circuits can be upgraded and replaced to keep the T 778 forever young and capable. This NAD innovation is a unique architecture that keeps pace with the fast-changing world of digital formats by allowing connectivity and feature upgrades as new technology becomes available. MDC defies premature obsolescence, so you can keep pace with the latest developments in high-performance AV through dealer-installed modules. Your T 778 can be upgraded as your needs and tastes develop, and you only need to replace the module you want to upgrade, not the entire AV Amplifier.

Fully Featured Surround

The T 778 carries on the enviable task of representing NAD’s finest surround sound performance. It offers full HDMI video switching and surround sound decoding to 7.2.4 channels. Brimming with a full array of sophisticated features like the high-resolution lossless surround formats from Dolby TrueHD and DTS Master Audio decoding, and now object-based audio with Dolby Atmos, the T 778 provides the highest levels of performance. The surround mode of the source material is automatically detected via the digital inputs of the T 778, and the most advanced form of decoding, based on your setup, is switched in. Conversion of the encoded digital bitstream is performed with high resolution and extremely linear D/A converters carefully selected for their performance capabilities.

Efficient Distortion-free Amplification

The T 778 features the latest developments in NAD’s Hybrid Digital technology to create nine high current and high power channels of amplification. These amplifiers exhibit no ‘crossover distortion,’ and are able to provide very high peak current for dramatic crescendos and impactful action scenes. The silent black background and explosive dynamics afforded by this amplifier technology add drama and excitement to your music and movies.

Undistort Your Listening Room

DIRAC Live room correction is now featured and offers a remarkable increase in fidelity by correcting both frequency response and time-domain impulse response. When properly calibrated, DIRAC Live improves clarity, naturalness, and pinpoint imaging.

Multi-room Network Music Streaming

BluOS™, the high-resolution audio multi-room music player shared with NAD’s sister brand Bluesound, is included in the T 778 making it unique among high-end AV Amplifiers. When connected to the Internet via Ethernet or Wi-Fi the T 778 has access to thousands of Internet radio stations and over a dozen high-quality music services including Spotify, Tidal, Deezer, and many more. With full support for MQA, the T 778 has the highest resolution audio performance available combined with the highest definition video performance.

Flexible Setup

The latest HDMI features, including HDCP 2.2, 4:4:4 color resolution, High Dynamic Range, and Dolby Vision video support, plus CEC/ARC, are all included. Digital inputs are available in both coaxial and optical formats to make it easy to attach all your digital sources. With BluOS™ NAD has also made it easy to add more speakers for listening to music in additional rooms. IR repeaters, 12V triggers to automatically switch amplifiers on and off, and an RS-232 data port make it easy to connect to highly advanced automated control systems, such as Crestron andControl4. Thoughtful features like discrete On and Off codes, direct access to inputs and music presets facilitate the integration of the T 778 into elaborate remote-control systems.

Customize with AV Presets

The T 778’s sleek LCD touch panel display makes setup and control easier than ever before. Unique features like AV presets and a completely flexible input setup allow unprecedented flexibility and ease of use. The T 778 offers five independent AV presets that store speaker level and tone control 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 if the program is so encoded. The T 778 also remembers your last used settings when switched in and out of Standby mode.

Complete and Compact

The T 778 combines all the control, decoding functions, and nine channels of amplification in one compact chassis that offers many options for installation in the home. Because of its highly efficient design, the T 778 is compact, ultra-quiet, and is rack-mountable for integration into complex home entertainment systems. The T 778 is an excellent example of the NAD Design Team’s expertise in digital decoding stages, video engineering, and analog amplification to offer the best overall performance. Along with the new touch screen and ergonomic refinements that simplify operation, the T 778 can be the dream command center of your home entertainment system.
