NAD MDC2 BluOS-D Module is an advancement in the second generation of the Modular Design Construction (MDC) platform for the C399 model. This new MDC2 design allows for the bi-directional transmission of signals between the module and host components. This significantly expands the array of upgrade possibilities for both the NAD C 399 HybridDigital DAC Amplifier and forthcoming MDC2-compatible devices.
With the incorporation of the MDC2 BluOS-D module, users can experience various advantages, including Dirac Live Room Correction, BluOS high-resolution multi-room streaming, music management, and more. Furthermore, NAD's MDC2 platform ensures that investments in components will remain compatible with upcoming advancements.
The MDC2 BluOS-D is the first expansion module offered by NAD that adds Dirac Live room correction to a two-channel component. Owners use the supplied calibrated microphone and intuitive Dirac Live app to analyze their room’s acoustics, and then upload correction filters to the MDC2 BluOS-D module. The MDC2 BluOS-D module can store up to five Dirac profiles for different listening positions and room conditions—for example, whether the drapes are open or closed.
As well as correcting peaks and dips in frequency response, Dirac Live optimizes impulse response by learning how sounds reflect off various surfaces in the listening space. The result is dramatically improved bass clarity, imaging, and timbral accuracy, on music and movie soundtracks.
The MDC2 BluOS-D module also features BluOS high-resolution music streaming. Available for iOS, macOS, Android, and Windows, the flexible BluOS Controller app provides access to hundreds of internet radio stations and more than 20 streaming services. Like all BluOS products, the MDC2 BluOS-D module supports high-resolution playback up to 24-bit/192kHz, as well as MQA. With the MDC2 BluOS-D module, users can share music from any source connected to the host component with up to 63 BluOS-enabled components on the same network. Playback can also be controlled by Alexa or Google voice commands, and from smart home control systems from Crestron, Control4, Lutron, RTI, and others.
Not only does the MDC2 BluOS-D module include the latest Wi-Fi and Ethernet protocols, but it also supports Apple AirPlay2, Spotify Connect, and Tidal Connect, and incorporates two-way Qualcomm aptX HD Bluetooth. There’s also a USB port for playing music from a connected USB drive. With an MDC2 BluOS-D module installed, MDC2-capable components can play music from a vast range of local, networked, and cloud-based sources. And thanks to its bidirectional communications architecture, MDC2 is ready for technology upgrades that have yet to be conceived.
