Introducing the T 778 A/V Surround Amplifier

BluOS Enabled 4K Ultra HD Receiver with Immersive Sound

NAD’s reference Audio Video Receiver (AVR) is a cutting-edge powerhouse for state of the art music and home theater. Well known for our high value/ high performance reputation in the AVR category, the brand’s reference model builds on that legacy with an expansion of unwavering philosophy of real-world performance, simplicity of operation, and future upgradeability.

Efficient Distortion-free Amplification

The T 778 features the latest developments in NAD’s Hybrid Digital technology to create 9 high current/high power channels of amplification with improved efficiency. Designed with NAD’s full disclosure approach to power ratings, the NAD AVR conservatively delivers 85W FDP and 9 x 140W FTC, all channels driven at rated distortion. For flexibility, the amp channels are configurable to be used for surround or second zone audio. The silent black background and explosive dynamics afforded by this amplifier technology adds lifelike realism, drama and excitement to all your music and movies.
