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 locally by
the NAC-N 172 XS. 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
),
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
search the list alphabetically.
Once playback is underway the NAC-N 172 XS 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, track genre and stream (audio file)
information.
Note:
Buffer level indicates the quantity of stored data
within the NAC-N 172 XS and reflects the ability of the
network to provide data at the necessary rate.
NAC-N 172 XS UPnP™ Audio Inter face
7 NAC-N 172 XS UPnP™ Audio Interface
In addition to providing the network connection required for internet radio playback,
the NAC-N 172 XS network interface enables audio files stored on UPnP™ servers to be
streamed and played. NAC-N 172 XS must be connected, either wirelessly or via Ethernet
cabling, to a network router. If the router provides an internet connection it should
incorporate a firewall. If NAC-N 172 XS is already connected to a network, begin by
selecting the UPnP™ input.
7.1 UPnP™ Servers
UPnP™ servers incorporate a software application that
allows the NAC-N 172 XS, or any other UPnP™ compatible
player, to play audio stored and streamed by another
device on the network. The UPnP™ server is usually a PC or
Mac 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
built in UPnP™ support and a variety of third party UPnP™
applications are also available that are compatible with
both Windows and Macintosh operating systems.
In the case of the Windows UPnP™ server the following
steps must be taken before music can be streamed to the
NAC-N 172 XS:
• 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.
7.2 Audio File Compatibility
The audio files stored on the UPnP™ servers attached to
the network may be in 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 Apple iTunes FairPlay system.
7.3 Scanning Servers and Playing Files
When the NAC-N 172 XS 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 Apple or Windows
PCs and provides access to
media files and iTunes library
contents from UPnP™ media
players such as NAC-N 172 XS.
