* iRadio/Streaming Services are output as 16 bit data at the appropriate
sample rate for the decompressed data. The sample rate will be 32kHz,
44.1kHz or 48kHz depending on the streams sample rate.
Incoming streams of less than 32kHz sample rate cannot be output over S/P
DIF /Toslink.
For compressed streams the true resolution of the audio is of course limited
by the encoding.
For Media content from local drives or UPnP this outputs in its native resolution
of 16- 24 bits, 32 kHz 44.1kHz 48kHz or 96kHz with bit for bit transfer.
** 88.2kHz material is not supported.
Troubleshooting
If you experience any trouble with your NP30, then you may find it useful to visit
the help section on our webpage at http://support.cambridgeaudio.com/.
If you have trouble with the UuVol service then you may also find it useful to
visit the help section at www.UuVol.com.
General Help guidelines:
If you have trouble connecting the NP30 to your network, these steps may
help to resolve the problem:
• Confirm that a connected PC can access the Internet (i.e. can browse the
web) using the same network.
• Check that a DHCP server is available, or that you have configured a static
IP address on the NP30. You can configure a static IP address on the NP30
using the menu item ‘Settings -> Network Config -> Edit Config’, and then
select ‘No’ for ‘Auto (DHCP)’. DHCP is however the recommended method.
• Check that your network’s firewall is not blocking any outgoing ports. As a
minimum, the radio needs access to UDP and TCP ports 80, 5 54, 1755,
5000, 6000 and 7070.
• Check your access point does not restrict connections to a particular MAC
addresses. You can view the radio’s MAC address using the menu item
‘Settings -> Network Config -> View Config -> MAC address’.
• If you have an encrypted Wi-Fi network, check that you have entered the
correct key or passphrase into the NP30. Remember that text-format keys
are case sensitive. If, when attempting to connect to an encrypted network,
your NP30 displays: ‘Wireless error’ followed by a 5-digit number, then please
ensure that you enter the correct passphrase for the network. If the problem
persists, then you may need to consult your network configuration.
If your NP30 can connect to the network successfully, but is unable to play
particular UuVol stations, it may be due to one of the following causes:
• The station is not broadcasting at this time of the day (remember it may be
located in a different time zone).
• The station has reached the maximum allowed number of simultaneous
listeners.
• The station is not broadcasting anymore.
• The link in our database is simply out of date.
• The Internet connection between the server (often located in a different
country) and you is slow.
• Try using a PC to play back the stream via the broadcaster’s web site.
If you can play back the station with a PC, you can use the form at
www.UuVol.com to notify us so that we can investigate.
If you have problems with UPnP playback always check the following:
• Ensure your chosen UPnP server software is capable of serving the file type
you are trying to access. Some servers do not serve FLAC for instance.
• The NP30 can only play non DRM files. Files that have DRM controls cannot
be played by the NP30. Some servers may be able to authorise and de-crypt
Microsoft Playsforsure before then serving the content to the NP30 but this
operation is not guaranteed as it is purely a function of the server.
• If attempting to play 24 bit WAV or FLAC content note a wired Ethernet
connection is normally required for reliable operation due to bandwidth
considerations.
• Check the NP30 is capable of playing back the file type you are trying to
access. WMA, AAC, MP3, Vorbis, FLAC and WAV can currently be played. The
NP30 does not support ALAC, WMA Pro, WMA lossless, RAW, AU or other file
types not mentioned.
If you have problems with Local Media playback always check the following:
• Check the NP30 is capable of playing back the file type you are trying to
access. WMA, AAC, MP3, Vorbis, FLAC and WAV can currently be played.
• The NP30 does not support ALAC, WMA Pro, WMA lossless, RAW, AU or other
file types not mentioned.
• For local media the NP30 can only play non DRM files. Files that have DRM
controls cannot be played.
• Check that your device does not require more than 500mA if it is powered
from the USB socket itself.
• Check your device is formatted in FAT32 format.
• The way you organise your local media affects the size of internal database
the NP30 needs to build dynamically as you browse content. Good practice
is to create folders for Artists within which you should have a sub folders for
each Album which then containing the tracks for that Album. Libraries with
thousands of tracks in one folder will progressively slow down the NP30s
media browsing.
