8. Network Audio Streaming

8.1 UPnP™ Streaming

NAC-N preampliers can play audio stored on any device

that incorporates UPnP™ server software (provided that

device is on the same network as the NAC-N preamplier).

The UPnP™ server is usually a Windows or Apple home

computer, although some Network Attached Storage (NAS)

drives incorporate a UPnP™ application.

Note: The Naim UnitiServe and HDX hard disk music

players can operate as UPnP™ servers.

Windows Media™ Player version 11 or above incorporates

UPnP™ support and a variety of third party UPnP™

applications are also available that are compatible with both

Windows and OS X operating systems.

In the case of the Windows UPnP™ server, the following

steps must be taken before music can be streamed to a

NAC-N preamplier:

• Ensure Windows Media™ Player version 11 or above is

installed.

• Enable Windows Media™ Player le sharing. From

the Media Player Options dialogue select Library >

Congure Sharing… then select Share my media.

• Ensure the rewall is congured to allow le sharing.

8.1.1 Audio File Compatibility

The audio les stored on the UPnP™ servers attached to

the network may be in DSD (NAC-N 272 only), MP3, M4A,

ALAC, AAC, LPCM16/24, FLAC, WMA, WAV, AIFF or Ogg

Vorbis formats. Files must be free of any digital rights

management playback restrictions such as the iTunes

FairPlay system.

8.1.2 Scanning Servers and

Playing Files

When the NAC-N preamplier

UPnP™ input is selected a list of

available UPnP™ servers on the

network will be displayed. The display will automatically

enter list mode so the handset up (5), down (6) and ok/

list keys can be used to browse and

select the desired server.

Note: Allegro Media Server

(shown in the illustrations) is a

UPnP™ Media Server application

that runs on OS X or Windows

computers and provides access to media les and iTunes

library content from UPnP™ media players.

The manner in which the UPnP™

server is set up will dene how the

audio les and playlists it holds are

listed and displayed. In most cases

the default setup will list and display

les by artist and album, but list by genre and predened

playlists may also be available.

Note: Playlists cannot be generated or stored on the

NAC-N preamplier. To play a playlist it must reside on

the UPnP™ server.

Selecting one of the playlist

categories using the up (5), down

(6) and ok/list keys will display a

menu showing items that fall into

the selected category. An entire

category can be selected for playback by using the up (5),

down (6) keys followed by the play/pause ( ) key.

Alternatively, selecting a category using the up (5) and

down (6) keys followed by the ok/list key will display the

full list of tracks contained within the category. Tracks can

then be selected for playback by using the up (5), down

(6) and ok/list keys.

In long lists the handset numeric/text keys can be used to

jump through the list alphabetically.

Once playback is underway the NAC-N preamplier display

will exit from list mode and revert to normal mode where the

handset transport keys ( ) can be used to control

playback. To re-enter list mode for further list browsing and

selecting press the handset ok/list key.

During playback, pressing the handset info ( ) key will

sequentially display the server name, buer level, track

elapsed time and stream (audio le) information.

Note: Buer level indicates the quantity of stored data

and reects the ability of the network to provide data at

the necessary rate.

In addition to enabling internet radio to be played, a NAC-N preamplier network connection enables audio les stored on

UPnP™ servers, audio streams from Spotify

Connect devices, and audio streams from other Naim streamers to be played.

Your NAC-N preamplier must be connected, either wirelessly or via network cabling, to a network router. If the router

provides an internet connection it should incorporate a rewall.
