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.

Note that for any given audio codec, there are 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.

Codec	Maximum supported data rate
AAC (LC)	320 kbits/sec
LPCM (1)	1.536 Mbits/sec
MP3	320 kbits/sec
WAV (1)	1.536 Mbits/sec
WMA (2)	320 kbits/sec

All codecs support 2-channel (stereo) coded ﬁles only.

All codecs support sample rates up to 48 kbits/sec (includes 32 and 44.1 kbits/sec).

Files which have Digital Rights Management (DRM) protection applied will not be playable on your radio.

(1)The maximum supported bit-rate is for 48 kHz sampling, 2 channels and 16-bits per sample.

(2)WMA Lossless, WMA Voice, WMA 10 Professional, and ﬁles which have DRM protection are not supported.
