* Steep filter disabled
* 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-bit, 32kHz 44.1kHz 48kHz or 96kHz with bit for bit transfer.

If you experience any trouble with your CXN, then you may find it useful to visit

If you have trouble with the Stream Magic service then you may also find it

General Help guidelines:
If you have trouble connecting the CXN to your network, these steps may help

to resolve the problem:
• Confirm that a connected computer 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 CXN. You can configure a static IP address on the CXN

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 CXN. Remember that text-format keys

are case sensitive. If, when attempting to connect to an encrypted network,

your CXN 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 CXN can connect to the network successfully, but is unable to play

particular Stream Magic 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 computer to play back the stream via the broadcaster’s web site.
If you can play back the station with a computer, you can use the form at

www.stream-magic.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 CXN can only play non DRM files. Files that have DRM controls cannot

be played by the CXN. Some servers may be able to authorise and de-crypt

Microsoft Playsforsure before then serving the content to the CXN 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 CXN 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 CXN does not support ALAC, WMA Pro, WMA lossless, RAW, AU or

other file types not mentioned.
