More details on the NAD MDC BluOS 2

The NAD MDC BluOS 2 replaces these items:

Product Research


Compatibility: NAD's MDC BluOS 2 module allows you to easily integrate Hi-Res Audio, network streaming, Bluetooth audio, and the music control BluOS App into select NAD C series digital integrated amplifier and Masters series digital preamplifiers.

Note: Make sure the M32, M12, C 390DD, C 368, or C 388 have the latest firmware update installed.

Powerful ARM Processor: The BluOS-2 module has a new more powerful ARM Processor for a quicker, more responsive user experience than the previous MDC DD BluOS module.

BluOS: Featuring BluOS, the music management software developed by NAD's sister brand, Bluesound, the MDC BluOS 2 module is a complete digital music solution. Thanks to the forward-thinking innovation of Modular Design Construction (MDC), you can now add MDC BluOS 2 network and internet music streaming with advanced music management to your NAD C series digital integrated amp or Masters series digital preamplifier.

Note: Up to 16 Bluesound devices can be connected in a strictly wireless environment. If you want to connect more than 16 Bluesound devices, you will need to connect the Bluesound devices to your network using a wired connection. Bluesound can then control up to 64 devices in a strictly wired environment.

Wired or Wireless Network Connection: The MDC BluOS 2 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. Both Ethernet and WiFi operate in asynchronous mode for the lowest jitter performance.

Note: Included with the MDC BluOS 2 module is a WiFi dongle that must be plugged into one of the module's USB (type-A) ports for wireless connection to your network. A 41" USB extension cable is also included.

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 BluOS 2 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.

Compression File Type Sampling Frequency Bit Rate or Bit Depth
Compressed Lossy MP3 16-48kHz 192-320 kbps
Lossless WMA-Lossless up to 96 kHz up to 24-bit
FLAC 192 kHz up to 24-bit
Uncompressed AIFF up 192 kHz up to 24-bit
Note: Bluesound cannot index or play AAC files with the extension ".m4p". These files were purchased in iTunes prior to 2009 and are subject to copy protection. Apple Consumers with an iTunes Match subscription can delete and re-download these files free of charge from their iTunes Cloud

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.

Note: MQA (Master Quality  Authenticated) support will require a firmware update.

Online Music Services: With a network and internet connection, the MDC BluOS 2 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.
  • TIDAL: TIDAL is a global streaming service that offers over 30 million songs in high-fidelity CD sound quality. TIDAL has two pricing tiers; either $9.99 or $19.99 a month. Both pricing levels allow you to access TIDAL's entire music library. The $19.99 tier has the added benefit of high-fidelity sound at CD-level quality
  • TuneIn: The Bluesound eco-system includes access to more than 70,000 free internet radio streams from all corners of the globe via the TuneIn radio service. Just select the TuneIn logo from the main Music menu and browse among the 70,000 stations neatly organized into popular categories and select a station that appeals to your mood.
  • iHeart Radio: iHeartRadio is a free, all-in-one digital radio and music streaming service that lets you listen to thousands of live stations from across the country and allows you to create personalized custom stations featuring songs from the artist you select and similar music.
  • Napster: Napster is a streaming music subscription service (starting a $10 per month) that allows you to play the full-length songs you choose on demand from a collection of over 10 million songs, without ads and without having to purchase or download the music.
  • Slacker: Get the sound quality that you deserve with the new Slacker Radio® music library available in high-quality AAC audio on Bluesound. Listen to music streams at a bitrate of 320kbps and enjoy all your favorite Slacker stations in pristine MP3-quality.
Note: Availability of online music services may vary by region. Not all services may be available at time of purchase. Some services may be added or discontinued from time to time based on decisions of the music service providers or others.

Music Library From Your Mobile Device: From the Bluesound Controller App, you can stream music directly over WiFi from your Apple iOS or Android device to your compatible NAD digital integrated amplifier or digital preamplifier and the rest of your Bluesound components around your home. 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 BluOS 2 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 BluOS 2 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 BluOS 2 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.

Note: The included Bluetooth antenna must be screwed into the DD BluOS module.

Dual USB-A Ports: The MDC BluOS 2 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.

Note: There is also a mini-USB (type-B) port that is used for service purposes only (not for consumer use). Only authorized service personnel can access this USB port.

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'.

1 question already asked

How is MDC BluOS 2 module different from module that comes with C368 BluOS?
[ Oleg  Mar 02, 2018 ]
4 answers
When researching on NAD website it appeared that the BluOs 2 was an updated product so I purchased the amp and module separately. It was a little more expensive that way but I thought it would be better to have the most current version. I love my DAC C 388
[ hal  Mar 05, 2018 ]
The BluOS 2 module is the same as the original except for a faster processing chip. The functionality is the same but it works a little faster and some problems I had with hi-rez 192 MQA files went away when I upgraded.
[ Ron  Mar 04, 2018 ]
If the module that comes with the C368 is the original BluOS module , then I believe the only difference is a new processor.
[ Jim  Mar 02, 2018 ]
I don't know what the difference is but the Bluos 2 is the latest version. Same cost to buy it separate. I installed it myself in the C368. Easy.
[ Alan  Mar 02, 2018 ]
