HybridDigital Hypex nCORE Amplification
Trickled down from NAD’s Masters Series, the C 399’s HybridDigital nCore amplifier is highly efficient and remarkably powerful. It can deliver 180 watts per channel of continuous power, and 250 watts per channel of instantaneous power, allowing the C 399 to reproduce musical transients effortlessly. The HybridDigital nCore design is renowned for its wide bandwidth, flat frequency response, clean clipping behavior with instant recovery, high-current capability, and stability into demanding low-impedance speaker loads. Noise and distortion are vanishingly low under all operating conditions. The minute levels of harmonic distortion are dominated by sonically benign second and third harmonics. These refinements enable the C 399 to produce neutral, distortion-free sound even at very high listening levels, with thrilling dynamics, exquisite detail, and superb portrayal of space.
High-Resolution ESS Sabre DAC
Also trickled down from the Masters Series is the ESS Sabre 9028 high-resolution DAC, a design noted for its wide dynamic range, ultralow noise and distortion, and near-zero levels of clock jitter. This premium DAC enables the C 399 to reproduce all your digital sources with amazing musicality, precise sound staging, and stunning clarity.
MDC2
MDC2 is the second generation of NAD Electronics’ innovative Modular Design Construction futureproofing technology. Introduced in 2006, MDC lets owners of NAD components add exciting new capabilities such as Dolby Atmos immersive audio, 4K video switching, and BluOS multiroom music streaming. Debuting on the NAD C 399, MDC2 features an all-new architecture that allows signals to be passed back and forth between the module and host component. This opens a far wider range of upgrade options for the C 399, and future MDC2-enabled components.
MDC 2 BluOS-D
Included with this model is the optional MDC2 BluOS-D module, which lets listeners play music from their favourite streaming services through the C 399. 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 theMDC2 BluOS-D to stream music from sources connected to the C 399 to BluOS-enabled components in other rooms. BluOS supports music streaming to up to 63 zones.
Dirac Live Room Correction
The MDC2 BluOS-D comes with Dirac Live Limited Bandwidth (20 Hz to 500 Hz) 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 399.
Smart Home Control
The C 399 comes equipped with IR remote, 12V trigger in and out, IR in and out, and an RS-232 serial port to allow seamless integration with smart home control systems such as Control4, Crestron, RTI, URC, Push, Lutron, iPort, and Elan.
