8. Network Audio Streaming
8.1 UPnP™ Streaming
NAC-N preamplifiers can play audio stored on any device
that incorporates UPnP™ server software (provided that
device is on the same network as the NAC-N preamplifier).
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 preamplifier:
•
Ensure Windows Media™ Player version 11 or above is
installed.
•
Enable Windows Media™ Player file sharing. From
the Media Player Options dialogue select Library >
Configure Sharing… then select Share my media.
• Ensure the firewall is configured to allow file sharing.
8.1.1 Audio File Compatibility
The audio files 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 preamplifier
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 files and iTunes
library content from UPnP™ media players.
The manner in which the UPnP™
server is set up will define how the
audio files and playlists it holds are
listed and displayed. In most cases
the default setup will list and display
files by artist and album, but list by genre and predefined
playlists may also be available.
Note: Playlists cannot be generated or stored on the
NAC-N preamplifier. 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 preamplifier 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, buffer level, track
elapsed time and stream (audio file) information.
Note: Buffer level indicates the quantity of stored data
and reflects the ability of the network to provide data at
the necessary rate.
In addition to enabling internet radio to be played, a NAC-N preamplifier network connection enables audio files stored on
UPnP™ servers, audio streams from Spotify
® Connect devices, and audio streams from other Naim streamers to be played.
Your NAC-N preamplifier must be connected, either wirelessly or via network cabling, to a network router. If the router
provides an internet connection it should incorporate a firewall.
