C 388 Hybrid Digital DAC Amplifier
The C 388 Hybrid Digital DAC Amplifier is at the top of its class in the world of affordable amplification. An incredibly powerful amp, the C 388 employs NAD technologies like Asymmetrical PowerDrive™ to ensure that even the most demanding speakers can be driven to life-like listening levels without dynamic compression. Thanks to its advanced preamplifier circuit, the C 388 gives low noise at all volume settings, ensuring that you’ll be able to listen to your music without any distractions. Another technology that’s available to the C 388 is the BluOS™ module, a music management system that can stream your music library wirelessly across your home Wi-Fi network. Connect to the C 388 instantly with Bluetooth® to give you access to various streaming services. With the ability to accommodate a variety of sources both past and present, the C 388 is a remarkably flexible product that will become a core addition to your home audio system.

Expansive Power with Unprecedented Flexibility.
The C 388 ties together all the critical elements of a top performing music system; music sources past, present, and future, in addition to providing a nearly unrestricted reservoir of power that allows your speakers to reveal every nuance of musical detail. This advanced amplifier includes many cutting edge technological breakthroughs developed by NAD over decades of creating affordable ultra-high performance audio components.
Getting the Basics Right
It is surprising how many seemingly advanced products in the market today often miss many of the most basic requirements for satisfying performance. NAD starts by getting these things precisely right and advances from there. We include an MM Phono stage with precisely accurate RIAA equalization, high overload margins, extremely low noise, and an innovative circuit to suppress infrasonic noise that is present on all LPs – all without affecting bass response. Our line inputs can accommodate all kinds of analogue source components by offering ideal input impedance characteristics with linear ultra-low-noise buffer amplifiers to prevent any sonic degradation. We include a separate headphone amplifier with low output impedance and very high output voltage capability – enough to drive even high impedance studio monitor headphones. Low impedance line outputs that can connect to other amplifiers or subwoofers extend the versatility of this well thought out amplifier.
Future-Proof Modular Design
This NAD exclusive feature allows you to customise your NAD amplifier with additional capabilities and features, now or in the future. The two available MDC slots can accommodate a variety of upgrade modules including 4K video capable HDMI switching, additional Digital Inputs, additional Analogue and Phono Inputs, and one of the most advanced Hi-Res Audio multi-room wireless systems available, the BluOS® music management system developed by Bluesound. BluOS connects to your network and is controlled via smartphone, tablet, or desktop device to manage your music collection and connect to a growing list of high-quality streaming music services.
Connected and Smart
Connect instantly to the C 388 via Bluetooth® aptX® to allow you to stream music wirelessly from any Bluetooth-enabled device with true CD-quality sound. Bluetooth can also be used to listen to other sources connected to the C 388 via wireless headphones such as NAD’s own HP70. There is also a control app that allows your mobile devices to control all functions of your C 388. Add the optional BluOS Module to provide access to your local area network via Wi-Fi or wired Ethernet connection and adds Hi-Res Audio streaming. The BluOS Module also makes the C 388 a single-zone streamer in a complete multi-room wireless music system that is fully compatible with BluOS Enabled music systems and wireless speakers.
Sophisticated Power
NAD has moved away from the old-fashioned power-hungry linear power supplies and Class AB output stages that waste nearly half of the energy consumed and produce heat rather than sound. Instead, we have developed even better performing circuits based on switch mode power supplies and Class D output stages. Once thought to be inferior to traditional topologies, NAD’s advanced work in this area has created some of the best performing amplifiers regardless of basic design principle. These new designs are very linear over a wide bandwidth and provide consistent performance into all speaker loads, providing a dramatic advance over previous models.
The power supply is capable of 150 watts continuously and over 250 watts instantaneously to allow for short-term musical transients. It can operate with any AC mains voltage from 100 to 240 volts and provides pure DC power to all the various stages of the C 388. This highly efficient supply also provides near perfect regulation of voltage across a wide range of conditions and provides a solid noise-free foundation for the amplifying stages.
The C 388 uses a customized version of the proven Hypex UcD output stage operating in a fully balanced bridge configuration. This allows for massive power with nearly immeasurable distortion and noise in the audible range. Every detail of this design has been carefully planned and perfectly executed to produce out every last drop of performance.

BluOS multi-room music streaming
Easily integrate Hi-Res Audio, network streaming, and music control. Featuring BluOS, the music management software developed by NAD’s sister brand, Bluesound, the BluOS 2i module is a complete digital music solution at an amazingly affordable price. Thanks to the forward-looking innovation of Modular Design Construction, you can now add BluOS network and internet music streaming with advanced music management to your NAD C 390DD, NAD Masters M12 and M32 or the NAD Classic models C 368 and C 388.
For Easy Integration
Compatibility
C 368, C 388, C 390DD, M32, M12
The BluOS 2 module has a new more powerful ARM Processor for a quicker, more responsive user experience. As an internal module there are no external wires or power supplies required and integration with the firmware is hand-in-glove. Both Ethernet and Wi-Fi operate in asynchronous mode for lowest jitter performance and allow connection to music stored anywhere on the local network or streamed directly from the Internet using popular music services like Spotify Connect, Tidal, and TuneIn. You can also play music from a USB drive or hard drive via the USB A port. Bluetooth® with aptX is also natively integrated so you can wirelessly connect to any smartphone, tablet, or Bluetooth-enabled device within range and stream your favourite music apps or libraries in high-fidelity.
BluOS is accessed using the local area network and free apps for mobile devices and desktops to control and manage your music BluOS also integrates with many third party home automation systems.
HANDS-FREE VOICE CONTROL WITH ALEXA.
Add the BluOS Voice Skill inside the Amazon Alexa app and enjoy hands-free voice control of personal music collections, streaming services and more using a list of simple streamlined commands. Using an Echo device you can ask Alexa to play popular songs from Tidal, queue up saved playlists, adjust the volume in different rooms, or ask what’s playing in the Kitchen. No Echo device and want to try it out? No problem. Download the Amazon Alexa app, activate the skill, tap the speech bubble in the bottom drawer of the Amazon Alexa app and say anything from the list of commands.
While the expected functions of Play/Pause/Skip are present, BluOS also brings all of your music together integrating locally stored music (like iTunes) and music streaming services. BluOS does not rely on middleware like UPnP/DLNA/AirPlay with their inherent limitations, but instead creates direct shares with music in all formats including FLAC, ALAC and WAV with data rates up to 24/192. Playlists can be created and managed right inside the BluOS App. Gapless playback is supported and the BluOS-2 module is fully compatible with Bluesound High-Res Wireless Multi-room Players to form integrated whole-house systems.
With AirPlay 2*, you can connect multiple AirPlay-enabled devices around the house and have them communicate with each other through AirPlay. Listen to your music in perfect sync as you walk room-to-room, or play different songs in different rooms, and control everything on your Apple device. You can even say the song you want to listen to and where and let Siri take control of your music experience.
Includes an external USB WiFi module to optimize signal strength.
*Apple AirPlay 2 only currently available on the C 368 and C 388 when the MDC BluOS 2i is installed.
