NAD C 379 BluOS

MAXIMUM POWER AND PERFORMANCE

Every detail of the C 379 amplifier design has been refined for maximum performance. Starting with a customised version of the proven HybridDigital UcD output stage, the C 379 operates in a fully balanced bridge configuration. This allows for massive power with nearly immeasurable distortion and noise in the audible range. The power supply is capable of 80 watts continuously and over 120 watts instantaneously to allow for short-term musical transients. For even greater power, the C 379 can be bridged in mono with the C 268 to provide up to 300 watts per channel of distortion-free sound.

BRILLIANT MUSICALITY AND DETAIL

The C 379’s digital architecture is built around the critically acclaimed ESS SABRE^® ES9028 DAC, one of the industry’s highest performance 32-bit digital-to-analogue converts with unprecedented dynamic range and ultra-low distortion. It provides ultra-high-quality music playback, free from clock jitter common in digital audio systems. The results are an exceptionally wide dynamic range, ultra-low distortion, accurate sound stage and unparalleled clarity.

FUTURE-PROOF FLEXIBILITY

Since 2006, NAD has led the way in providing users the flexibility to add features as new A/V technologies are introduced to provide unparalleled performance and value. Now, with the second generation of NAD’s Modular Design Construction (MDC) technology, the C 379 is in a class of its own. It features two MDC2 slots for upgrading the amplifier’s capabilities with emerging A/V technologies and additional features, including BluOS^® high-resolution multi-room streaming and Dirac Live Room Correction.

THE POWER OF BLUOS

With the available MDC2 BluOS-D module, Dirac Live, BluOS, Apple AirPlay 2, two-way aptX^® HD Bluetooth, and more, can be added to the C 379. With BluOS, the C 379 can be connected to a home network via Wi-Fi or Ethernet to experience the most advanced multi-room wireless music management system with 24 bit/192kHz resolution. Controlled through the BluOS app for smartphone, tablet, or desktop, BluOS manages your digital music collection and connects to over 20 high-quality streaming music services including Tidal, Deezer, Qobuz, Amazon Music, Spotify, and more.

CONNECT EVERYTHING

The C 379 is well equipped with a variety of analogue and digital connectivity options including aptX HD Bluetooth, HDMI eARC, MM Phono stage, and two subwoofer outputs. aptX HD can easily support 24-bit streaming from any Bluetooth enabled device, while HDMI eARC allows you to connect the C 379 to your TV and provide seamless control from your existing remote. It also includes a built-in high-performance headphone amplifier with low output impedance and high output voltage capability, allowing it to drive a wide range of headphones.

NAD Modular Design Construction2 BluOS-Dirac Module

Compatibility

C 399 Hybrid Digital DAC Amplifier, C 389 Hybrid Digital DAC Amplifier, C 3050 Stereophonic Amplifier

NAD Electronics is proud to announce the next generation of our innovative Modular Design Construction future-proofing technology, which allows owners of NAD components add exciting new features simply by performing a software upgrade and slipping a hardware module into an MDC slot on the back panel. Modular Design Construction2 features an all-new design that enables bidirectional communications between the module and host component, allowing a dramatically wider range of upgrade options.

NAD’s first MDC2-Enabled component is the C 399 HybridDigital DAC Amplifier. The module, MDC2 BluOS-D, adds Dirac Live room correction and BluOS multi-room music streaming to all compatible products listed above.

Dirac Live Room Correction

The weakest link in most sound systems is the listening environment. Room modes can cause boomy, uneven bass response; and reflections of sounds from room surfaces can smear transients and disrupt stereo imaging. Dirac Live analyzes room acoustics, and then uploads compensation filters to the MDC2 BluOS-D module. The MDC2 BluOS-D module corrects peaks and dips at frequencies up to 500Hz, which is the area where room modes are most problematic; a license for the full-bandwidth version of Dirac Live is available as an option. Dirac Live also optimizes impulse response by analyzing how sounds are reflected off room surfaces.

With Dirac Live enabled, listeners will enjoy vastly improved bass clarity, imaging, and timbral accuracy on all sources. The MDC2 BluOS-D module can store up to five Dirac profiles for different listening positions or room conditions—for example whether the drapes are open or closed.

The MDC2 BluOS-D module is NAD’s first module to enable Dirac Live room correction on a two-channel component—a testament to the versatility of the MDC2 platform. A calibrated microphone is included for performing room measurements.

BluOS Music Streaming

The MDC2 BluOS-D module features BluOS, a multi-room high-resolution streaming platform acclaimed for its versatility and ease of use. With the MDC2 BluOS-D module installed, owners of the C 399 and future MDC2-enabled components can access hundreds of Internet radio stations and over 20 streaming services, including several that deliver lossless and high-resolution audio. Thanks to MDC2’s bidirectional architecture, users can share audio from any source with up to 63 other BluOS-enabled components on the same network.

Playback can be controlled from the intuitive BluOS Controller app, available for iOS, macOS, Android, and Windows; by Alexa or Google voice commands; and from smart home control systems such as Crestron, Control4, Lutron, and RTI. Like all BluOS devices, the MDC2 BluOS-D module supports high-resolution audio to 24-bit/192kHz, and can perform MQA hardware decoding and rendering.

Future-Friendly

The MDC2 BluOS-D module incorporates the latest Wi-Fi and Ethernet protocols, as well as two-way Qualcomm aptX HD Bluetooth. It supports Apple AirPlay 2, Siri voice control, Spotify Connect, and Tidal Connect. Listeners can also play music from their personal libraries, stored on an external drive connected to the MDC2 BluOS-D module’s USB port.

The MDC2 BluOS-D module provides a vast range of options for playing local, networked, and cloud-based content throughout your home. And with its bidirectional communications architecture, the MDC2 platform is ready for innovations that have yet to be conceived.
