9.2-channel home theater receiver with Wi-Fi®, BluOS™, Bluetooth®, Apple AirPlay® 2, and Dolby Atmos®

Power meets simplicity

This 140-watt-per channel home theater receiver can power even the largest surround sound systems. Yet it offers an intuitive touchscreen interface that makes changing sources and dialing-in settings a smooth experience.

Sound from every corner of your room

The T 778 supports cutting-edge “object-based” surround sound formats like Dolby Atmos and DTS:X, which place sound effects in space around you with pinpoint accuracy.

You can have up to nine speakers firing simultaneously and hear the movie’s score and special effects above, behind, in front of, and beside you — just like you would in an actual theater.

Flexible music streaming

NAD has included a kit that adds support for BluOS, a premium-quality wireless streaming platform that gives you access to a wide range of music.

The kit includes dongles for both Wi-Fi and Bluetooth, so you can access streaming music from the internet and content from your phone, wirelessly. There are also a pair of USB inputs for connecting thumb drives loaded with tunes, including high-res audio files up to 24-bit/192kHz.

The free BluOS mobile app gives you easy access to services like Spotify®, Amazon Music (including HD), TIDAL, and more. And it works with additional wireless speakers from Bluesound for enjoying music in multiple rooms simultaneously.

Designed with the future in mind

Clean, powerful amplification never goes out of style, and this NAD has that in spades. But with rapidly changing audio and video technology, it can be hard to commit to new gear when the next generation of tech may be on the horizon.

That’s why NAD developed a way to upgrade parts of the T 778 without having to replace the whole thing — a unique technology called “Modular Design Construction.”

The T 778’s digital inputs and outputs are built into removable circuit boards. If something more advanced comes along down the road, you’ll have the option to upgrade your connections without buying a whole new receiver.

Legendary room correction

This receiver includes Dirac Live®, one of the industry’s best room-correction platforms. Download the Dirac software to your Windows® or Mac® computer, and connect the supplied microphone. That’s when the magic starts.

Dirac takes precise acoustic measurements of your room, and creates a customized correction curve that fine-tunes the output of your speakers and subwoofers based on the unique sonic characteristics of your space.

In other words, you get smooth, clear sound that’s tailored to your room. The before and after can be startling, which shows just how valuable room-correction technology can be.
