Additional Information

About MP3
An MP3 file is audio data compressed by using the
MPEG1 audio layer-3 file-coding scheme. We call
files that have the ".mp3" file extension "MP3 files".
The unit can not read an MP3 file that has not ".mp3"
file extension.
About WMA
An WMA file is a Microsoft audio compression
technology.
WMA(Windows Media Audio) offers double the audio
compression of the MP3 format.
MP3/WMA Disc compatibility with this unit is
limited as follows:
1. Sampling Frequency / 8 - 48kHz(MP3),
32 - 48kHz(WMA)
2. Bit rate / 8 - 320kbps(MP3),48-320kbps(WMA)
3. CD-R physical format should be "ISO 9660"
4. If you record MP3/WMA files using the software
which cannot create a FILE SYSTEM, for example
"Direct-CD" etc., it is impossible to playback MP3
files. We recommend that you use "Easy-CD
Creator", which creates an ISO9660 file system.
