Modular Design Construction, first introduced by NAD in 2006, keeps your home audio system up to date by allowing cost effective hardware upgrades as new digital technologies are introduced. NAD’s innovative MDC technology has revolutionized the way audio systems are designed, eliminating early obsolescence due to unforeseen technological advances. Built for our Masters Series M17 AV Processor , the AM 17 features Dolby Atmos®, a technology that produces a soundstage that is both enveloping and expansive. This is achieved by adding a third dimension of height to surround sound, and evolving the 7.1 channel M17 into an eleven-channel surround processor supporting the Dolby Atmos 7.1.4 sound field. Utilizing the likes of Dirac Live™, one of the most modern room correction technologies around, the AM 17 is the perfect component for your audio system.
