Master Series Digital Music Player: A hybrid of NAD's renowned
Master Series M50
Digital Music Player and
M52 Digital Music Vault, the M50.2 Digital Music Player combines high-res music listening, multiroom
wireless streaming, 24-bit/192kHz storage, and CD ripping into one beautiful
Note: Pair the M50.2 Digital Music Player with one of NAD's
Master Series' preamplifiers
and power amplifiers, integrated amplifiers, stereo
receivers, or AV receivers (all sold separately).
CD Transport: The NAD M50.2 Digital Music Player features a
front-loading CD slot. The built-in CD transport can playback Audio CDs (CD-A)
only. The M50.2 will automatically start
playback of an inserted CD. Playback is different and much improved in the M50.2 over conventional
CD players. Instead of streaming directly from the disc to the output, the
M50.2 momentarily stores the data in a memory buffer where it is re-clocked to
the M50.2's high precision master clock for the lowest levels of jitter. Disc Ripping:
The M50.2's CD transport can rip an inserted
Audio CD directly to its built-in HDD thanks to NAD's own music management software. Ripping is completely
automatic. With a network connection to the Internet, this music management
software captures metadata and cover art, without the need for a computer.
Everything is organized and instantly available for playback. You can browse
your music collection using album art or category listing, and easily create
playlists on the fly. You can choose to rip your Audio CD music as MP3 or
- MP3 (default format): Standard audio compression
designed to keep bandwidth low with little degradation. Files are ripped
at 320kbps, the highest level of sound quality available to MP3 format.
- FLAC (recommended format): High quality compression
designed specifically for CD backup purposes. Files are ripped at FLAC
level 5 balancing compression and rip speed at full CD lossless levels
- Both: For Hi-fidelity quality playback with the
ability to export or download to a personal MP3 Player.
Note: For ripping of multiple CDs, insert the next disc
as soon as the current disc is ejected (it is not necessary to wait for
the encoding to be completed before the next disc is inserted). Only
Audio CDs can be ripped. It will not rip Blu-ray, DVD,
DVD-Audio, HD-DVD, or other types of Optical Disc format. The CD ripping
procedure can be stopped at any time by selecting "Eject CD".
HDTracks Ripping: You can also purchase, download, and store
high-res tracks (up to 24-bit/192kHz) from HDTracks
on the built-in HDD with no computer needed. Now, you'll be able to access
and share your entire digital music collection and stream it in studio-quality
quickly and easily.
Internal Hard Disk Drive (HDD): The NAD 50.2 Digital Music Player
features 4TB of internal redundant storage featuring RAID backup. You get 2TB of
music storage with another 2TV of mirrored back storage. Inside NAD M50.2
resides an ultra-low noise 2x 2TB (Terabyte) HDD array. These special low noise
media hard disc drives run cool and completely quiet. Unlike HDDs made for
general computing, the M50.2 drives do not require fans for cooling.
Note: Audio files stored on the HDD can be played back at the M50.2 and
wirelessly distributed to other Bluesound components in your home for multiroom playback.
RAID 5 Technology: The M50.2 Digital Music Player
provides a high level of protection for your valuable digital music collection.
Using a Redundant Array of Independent Discs (RAID 5) technology, the M52's two
2TB hard disc drives (HDD) make it nearly impossible to damage your music. Front
panel LED indicators display the status of the HDDs, and alert you if there is
an HDD failure. Even if a disc drive fails, you won't lose data; simply replace
the drive, and the system automatically reconfigures itself.
