MDC2 is the second generation of NAD's innovative Modular Design Construction technology. It makes it possible to expand the range of functions of numerous NAD components with optional modules - even retroactively. MDC modules with HDMI inputs, for BluOSTM Multiroom streaming, with Dolby Atmos® surround processing and other functions are currently available for the slots located on the rear of the device. First used in the NAD C 399 integrated amplifier, the MDC2 features a completely new architecture that allows data to be exchanged between the NAD component and the modules. This opens up a much wider range of upgrade options for the C 399 and future MDC2-enabled components.


The MDC2 BluOS-D module connects to the internet via WLAN and Ethernet and allows the listener to play music from numerous streaming services. This function is controlled via the BluOSTM Controller App available for Android, iOS, macOS and Windows. Like all BluOSTM-enabled products (from generation 2i), the new MDC2 module supports Apple AirPlay 2, Spotify Connect and Tidal Connect, high-resolution playback with up to 24 bit/192 kHz as well as playback of MQA data. Thanks to bidirectional communication, the MDC2 BluOS-D module can also be used to transmit music from local sources connected to the respective NAD component to up to 63 other BluOSTM-capable components in the same network. Integration into smarthome systems from Crestron, Control4, Lutron, Elan, RTI and others is also possible.


Another component of the MDC2 BluOS-D module is the innovative Dirac Live® room correction. Using an app and the microphone included in the scope of delivery, Dirac Live® measures the acoustics of the living room and then saves the correction curves in the module. Up to five Dirac profiles for different listening positions and room conditions - for example, for open or closed curtains - can be stored. Dirac Live® not only corrects peaks and dips in the frequency response, but also optimises the impulse response by analysing the reflections of the various surfaces in the listening room. The result is a dramatic improvement in bass precision, spatial imaging and soundstage balance for music and movies.


In addition to integration into WLAN or LAN networks, the MDC2 BluOS-D module is also capable of wireless reception of music data streamed from a smartphone, tablet or notebook via Qualcomm® Bluetooth® aptXTM HD. Since the Bluetooth® technology of the MDC2 module is designed to be bidirectional, music data can also be sent to Bluetooth® headphones, for example, at the same time. Finally, a USB port is available for connecting a separate USB hard disk to play the local music library. Thus, MDC2-enabled components in combination with an MDC2 BluOS-D module are able to play music from local, networked and cloud-based sources. And thanks to MDC2's bidirectional communication architecture, it is also already ready for future technologies.
