About the NAD MDC2 BluOS-D

Make your NAD C 399 wireless


This module adds BluOS multi-room streaming and Dirac Live room correction to your NAD C 399.

The MDC2 BluOS-D module adds two-way BluOS streaming and Dirac Live room correction to your NAD C 399 integrated amp (sold separately). It's the first add-on in NAD's next-generation architecture of the MDC (Modular Design Components) that they introduced in 2006 to "make obsolescence obsolete."

Part of a BluOS multi-room system

This module adds compatibility with Bluesound's BluOS wireless ecosystem. That means you can integrate your C 399 into a whole-home audio system that gives you easy access to all your favorite music. Stream songs on your main hi-fi system and send the music to other Bluesound speakers and components around your home, so the tunes follow you from room to room.

Flexible streaming options

BluOS can wirelessly transmit high-res music up to 24-bit/192kHz with no lag and zero loss in sound quality. Stream music from personal local drives or from internet streaming services. The selection of supported services — including TIDAL, Spotify®, Qobuz, and Amazon Music, among others — is one of the most impressive we've seen. You can also stream via Apple AirPlay® 2 or Bluetooth with high-quality aptX® HD audio coding.

New two-way communication also lets this module stream music from your connected sources — even a turntable — to BluOS components in other rooms.

A free app with advanced control options

Operate your system via Wi-Fi® using the BluOS Controller app with your Apple® or Android™ device, or your Windows® or Mac® computer. It gives you flexible control over your entire music system. Play the same song everywhere or stream different music to different zones at the same time. You can even use your Apple Watch to control your system.

Dial in perfect sound for your space

It's rare that you find an acoustically perfect space for your system. The module's Dirac Live function lets you compensate for your room's acoustics to get clear and accurate bass and a balanced soundstage across the audio spectrum. Use the supplied mic and free user-friendly app to measure your room's acoustics, then upload correction curves to the module. Thanks to its two-way architecture, the Dirac Live room correction works for all sources connected to the amp.
