Modular Design Construction: The advantages of a pure digital system are many, but one drawback is the constantly changing delivery formats for digital content. Each of these formats typically requires specialized hardware and software, often with licensed IP and content copy protection. For this reason, NAD places all digital interface circuitry on easily upgradable modules. NAD calls this 'Modular Design Construction' or 'MDC'.
DD HDM-1 HDMI Module: The NAD DD HDM-1 is a HDMI upgrade module for select NAD digital integrated amplifiers and Masters series direct digital stereo preamplifiers. The DD HDM-1 offers three HDMI inputs and one output with video pass through. This opens up the possibility of using your NAD C series digital integrated amp or Masters series direct digital preamplifier as the heart of a "Video 2.0" system using the mandatory two-channel linear PCM soundtrack (up to 24-bit/192kHz) from Blu-ray or DVD to make a compelling two-channel high definition theatre presentation. Many Symphony Orchestras and some specialty music labels are also released in HD recordings on Blu-ray or DVD. The DD HDM-1 is 1080p/60Hz & 3D video compatible, but there is no surround sound decoding or video processing.
Compatibility: NAD's DD HDMI-1 module is compatible with select NAD C series digital integrated amplifiers and Masters series digital preamplifiers.
