The NAD C 389 HybridDigital DAC Amplifier delivers award-winning performance, powerful HybridDigital amplification, and flexible upgradeability for modern music systems. Its 130-Watt-per-channel design and refined digital architecture bring exceptional clarity and control to every track. With dual MDC2 slots, the C 389 can be expanded with high-resolution BluOS streaming and Dirac Live Room Correction (Dirac Live® Limited Bandwidth licence and calibration microphone for room correction up to 500Hz - MDC2 BluOS-D card required). HDMI eARC, a precise MM phono stage, and versatile digital and analogue inputs complete a refined, future-ready foundation for everyday listening.
The optional MDC2 BluOS-D module lets listeners play music from their favourite streaming services through the C 389. 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 389 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 389.
