NAD Electronics just introduced the Masters Series M15HD Surround Sound Preamplifier, a versatile component designed to serve as the brains of any surround sound system. The M15HD offers NAD's Modular Design Construction (MDC) in addition to innovative circuit designs, proprietary operating software, broadcast-quality image processing, and exceptional sonic performance and value.

NAD's "Music First" design philosophy allows the space, scale, and transparency encoded in the directional sounds of Dolby and DTS surround soundtracks to push the boundaries of a listening room. Four HDMI inputs make it a practical choice for high-definition viewing; and NAD's special Masters Series Home Theater Remote, an 8-device, illuminated learning control with an LCD display, can learn commands for additional components.

The M15HD is a new High Definition edition of NAD's M15 Surround Sound Preamplifier. It is built around NAD's exclusive new Modular Design Construction (MDC) architecture, and configured with a VXP broadcast-quality image processor by Sigma Designs. The first Masters Series component boasting MDC, the M15HD provides numerous benefits. It improves performance, functionality and ease of use while protecting against premature obsolescence. It enables users to more quickly and economically add new advanced features from NAD while also simplifying servicing.

The cornerstones of MDC are easily removable A/V modules that include the circuitry for digital audio and HDMI functions, component and analog video functions, and two-channel and multi-channel analog audio functions, plus all the inputs and outputs needed for full connectivity.

Modular Muscle
The modules for the M15HD come packed with advanced features that include dual 32-bit Aureus 7.1 high-speed DSPs by Texas Instruments; Dynamic EQ, Dynamic Volume, and MultEQ Pro room correction technologies by Audyssey; decoding for advanced audio formats, including Dolby True HD, Dolby Digital Plus and DTS-HD Master Audio; and Sigma Designs' VXP broadcast-quality image processor.

Dynamic EQ preserves the impact of movie soundtracks at all listening levels, while Dynamic Volume prevents large loudness jumps when commercials come on, and TV channels or video sources are changed. Sigma's VXP-based solutions were developed in a broadcast environment, from a broadcast heritage. Coupled with advanced image enhancement algorithms, they comprise the most advanced single-chip image processor now available, and provide every source with the highest level of 1080p HD performance.
