Audio codecs

Your radio supports a range of audio codecs which provide compatibility with a wide range of Internet radio stations. These also allow users to stream
music from their computers or to play directly from USB fl ash memory devices.
Note that for any given audio codec, there are many variations of the codec and many streaming protocols available, and thus even if an Internet
radio station uses a supported format, this does not guarantee that every such station will work with your radio. The radio stations database to which
your radio connects is checked for compatibility so that most stations should be playable without problems. Similarly when streaming media from a
computer, while a codec may be supported, there can be many subtle variations in formats, tagging schemes and protocols (even within UPnP). In
general your radio will play the supported formats with most common UPnP servers.
The following table summarises the maximum supported bit-rates for the various audio formats that are playable on your radio. Higher rates may be
playable in some cases but performance of the product may be affected.
