MDC2 BluOS D module
  • MDC2 BluOS D module

    NAD Electronics is proud to announce the next generation of our innovative future-proof Modular Design Construction technology, allowing NAD component owners to add exciting new features by simply performing a software upgrade and installing a hardware module into an MDC slot on the rear panel to slide. Modular Design Construction2 features a completely new design that enables bi-directional communication between the module and the host component, creating a much wider range of upgrade options.

    Dirac Live Room Correction

    The weakest link in most sound systems is the listening environment. Room temperatures can cause boomy, uneven bass response; and reflections of sounds from surfaces in the room can blur transients and distort the stereo image. Dirac Live analyzes the room acoustics and then loads compensation filters to the MDC2 BluOS-D module. The MDC2 BluOS-D module corrects peaks and dips at frequencies up to 500Hz, the area where room modes are most problematic; a license for the full-bandwidth version of Dirac Live is available as an option. Dirac Live also optimizes impulse response by analyzing how sounds are reflected from room surfaces.

    When Dirac Live is enabled, listeners will enjoy greatly improved bass clarity, imaging and timbral accuracy across all sources. The MDC2 BluOS-D module can store up to five Dirac profiles for different listening positions or room conditions - for example whether the curtains are open or closed.

    The MDC2 BluOS-D module is NAD's first module to enable Dirac Live room correction on a two-channel component - a testament to the versatility of the MDC2 platform. A calibrated microphone is included for taking room measurements.

    BluOS Music Streaming

    The MDC2 BluOS-D module features BluOS, a high-resolution multi-room streaming platform that is praised for its versatility and ease of use. With the MDC2 BluOS-D module installed, owners of the C 399 and future components that support MDC2 will have access to hundreds of Internet radio stations and more than 20 streaming services, including several that provide high-resolution lossless audio. MDC2's bidirectional architecture allows users to share audio from any source with up to 63 other BluOS-compatible components on the same network.
