BluOS: Featuring BluOS, the music management software developed by NAD's sister brand, Bluesound, the MDC DD BluOS module is a complete digital music solution. Thanks to the forward-thinking innovation of Modular Design Construction (MDC), you can now add MDC DD BluOS network and internet music streaming with advanced music management to your NAD C series digital integrated amp or Masters series digital preamplifier.

Wired or Wireless Network Connection: The MDC DD BluOS module allows your compatible NAD integrated amplifier or digital preamplifier to connect to your home network and Internet provider via a hardwired Gigabit Ethernet (RJ-45) jack connector or wireless WiFi (802.11 b/g/n) connection. Either network/internet connection allows you to stream music from your Windows or Mac computer and NAS drive (such as the Bluesound Vault, sold separately); as well as stream select online music services.

Bluesound Controller App: The free Bluesound Controller App turns your Apple iOS (7.0+) iPod/iPhone/iPad, Android (OS 4.0+) smartphone/tablet, Windows (Vista higher) PC or Mac (OS X 10.7+) computer into a full-featured remote control for the Bluesound wireless music system. The Bluesound Controller App on your compatible device uses your home's WiFi network to connect with Bluesound devices, so you can play all the music you love anywhere in your home for a wireless multiroom music experience. Get on-demand access to your music libraries on your home network, stream live Internet radio from almost any place in the world, or listen to one of the many music services available on Bluesound, all from the palm of your hand with the easy-to-use Bluesound Controller App.

Supported Music Formats: The MDC DD BluOS module and Bluesound eco-system supports both low-res and high-res audio files; including MP3, AAC, WMA, OGG, FLAC, ALAC, WMA Lossless, MQA, WAV, and AIFF. Bluesound has been designed to work with today's larger music collections, and has indexed libraries up to 100,000 songs in demonstrated practice (this will depend on the music's metadata & artwork). Bluesound also offers gapless playback by default for all supported file music types.

MQA (Master Quality Authenticated): Bluesound is the first wireless multiroom audio system to support MQA (Master Quality Authenticated). MQA is a revolutionary end-to-end technology that captures and delivers master quality audio in a file that's small enough to stream or download. Bluesound worked closely with MQA to implement technology inside each Bluesound component to ensure the listener will hear MQA encoded music and streams exactly like the source and the way the artist intended you to hear it when it was approved in the studio.

Online Music Services: With a network and internet connection, the MDC DD BluOS module lets you access select online music services & internet radio. The Bluesound Controller app on your Apple iOS or Android device will serve as the controller for these apps and provide song/artist information with Album Art.

• Spotify Connect: If you subscribe to Spotify Premium and have the Spotify App on your Apple iOS or Android smartphone, you can stream Spotify to the Bluesound system. Spotify is a digital music service that gives you on-demand access to one of the largest music libraries in the world (over 15 million tracks and counting). Spotify makes it easier than ever to discover, manage, and share music with your friends. You can browse music by artist, album, track, or most popular; and create your own music library with customized playlists.

The app gives you complete control of your compatible mobile device's music library with song/artist information and album art.

Computer Audio: The MDC DD BluOS module will pull music from an existing digital music library across the network on your Windows PC or Mac computer using Windows or SMB File Sharing (SAMBA) and the Bluesound Controller App for Windows & Mac.

• Windows: Music files stored on a Windows desktop or laptop can be accessed by Bluesound using Windows File Sharing. You will need to download the Bluesound Share Utility for Windows. This utility will work on Windows Vista, 7, 8 and 10.
• Mac: Music files stored on an Apple iMac or MacBook can be accessed by Bluesound using SMB File Sharing. You will need to download the Bluesound Share Utility for OS X. This utility will work on any version of Apple OS X 10.8.x and higher.

Bluetooth w/ aptX: The MDC DD BluOS module features built-in Bluetooth 4.0 with support for wireless music streaming from your Bluetooth-enabled Apple iPod/iPhone/iPad, Android smartphone/tablet, Windows PC/Phone, Mac computer/laptop, and more. You'll be able to stream stored music and music apps on your Bluetooth-enabled device to your compatible NAD digital integrated amp or digital preamp. In addition, the MDC DD BluOS module offers aptX for CD-quality sound from Android (OS 4.0+) devices. You can even distribute Bluetooth audio to the rest of your Bluesound wireless audio system throughout your home or office over WiFi.

Dual USB-A Ports: The MDC DD BluOS module features two USB (type-A) ports to directly connect your USB mass storage class (MSC) device; such as a thumbdrive or external hard-drive. The unit's USB ports support music playback from these compatible USB devices formatted in FAT 32. Not only can USB audio be played back on your compatible NAD digital integrated amplifier or digital pramplifier, but can also be wirelessly distributed to the rest of your Bluesound components throughout your home for multiroom playback. The USB port is not compatible with the direct connection of an Apple iPod/iPhone/iPad or Android devices.

Modular Design Construction: The advantages of a pure digital system are many, but one drawback is the constantly changing delivery formats for digital content. Each of these formats typically requires specialized hardware and software, often with licensed IP and content copy protection. For this reason, NAD places all digital interface circuitry on easily upgradeable modules. NAD calls this 'Modular Design Construction' or 'MDC'.
