MDC2 UPGRADE SLOTS
C 3050 supports NAD’s MDC2 architecture. By enabling two-way
communications between the module and component, MDC2 opens up
the future for new upgrades.
MDC2 BLUOS-D
The optional MDC2 BluOS-D module lets listeners play music
from their favourite streaming services through the C 3050.
MDC2 BluOS-D is equipped with Wi-Fi and Ethernet and uses
the acclaimed BluOS Controller app for Android, iOS, macOS,
and Windows.
Like all BluOS-enabled products, the MDC2 BluOS-D has
integrated support for dozens of streaming services and
supports Apple AirPlay 2, Spotify Connect, and Tidal Connect.
Two-way communications also enable the MDC2 BluOS-D
to stream music from sources connected to the C 3050 to
BluOS-enabled components in other rooms.
The MDC2 BluOS-D comes with Dirac Live® Limited Bandwidth (20Hz –
500Hz) installed with the option for advanced users to upgrade to the
Dirac Live Full Frequency version. Dirac Live function lets you measure
your room’s acoustics using a supplied microphone and intuitive app, and
then upload correction curves to the MDC2 BluOS-D. By compensating for
acoustic anomalies in your listening environment, Dirac Live dramatically
improves bass clarity, imaging, and timbral accuracy. Thanks to its two-way
architecture, the MDC2 BluOS-D performs room correction for all sources
connected to your C 3050. For Dirac Live Setup guidelines, go to
support.nadelectronics.com and search for “Dirac Setup”.
