0 WMA is short for Windows Media™ Audio. WMA is able to compress audio data to about 1/2 the level of MP3.

0 The MP3/WMA player allows playback of MP3/WMA files on CD-ROM, CD-R and CD-RW discs.

Disc recordings compatible with level 1 and level 2 of ISO 9660 and with the Romeo and Joliet file system can be played back.

0 When naming a MP3/WMA file, and the corresponding filename extension (.mp3/.wma).

o The MP3/WMA player plays back files with the file name extension (.mp3/.wma) as an MP3/WMA file. To prevent noise and malfunctions, do not use this extension for files other than MP3/WMA files.

0 It is possible to play back multi-session compatible recorded discs.

o When playing discs with MP3/WMA files and audio data (CD-DA) such as CD-EXTRA and MIXED-MODE CD, CD-DA only can be played.

D Only when MP3/WMA files of 32, 44.1 and 48 kHz frequencies are played back, the emphasis function is valid. (MP3 files: 16, 22.05, 24 kHz sampling frequencies can be played back.)

D The sound quality of MP3/WMA files generally becomes better with higher bit rates. This product can play recordings with bit rates as follows: MP3 files: 64 kbps to 320 kbps WMA files: 48 kbps to 320 kbps But in order to be able to enjoy a certain sound quality, it is recommended to use only discs recorded with a bit rate of at least 128 kbps.

D The MP3/WMA player does not play back MP3/WMA files from discs recorder using packet write data transfer (UDF format). Discs should be recorded using "pre-mastering" software rather than packet-write software.
