MP3 overview

Notes on MP3:

 MP3 is short for MPEG Audio Layer 3 and refers to an audio compression technology standard.

 This product allows playback of MP3 files on CD-ROM, CD-R or CD-RW discs.

 The unit can read MP3 files written in the format compliant with ISO 9660. However it does not support

the MP3 data written by the method of packet write.

 The unit can not read an MP3 file that has a file extension other than “.mp3”.

 If you play a non- MP3 file that has the “.mp3” extension, you may hear some noise.

 In this manual, we refer to what are called “MP3 file” and “folder” in PC terminology as “track” and

“album”, respectively.

 Maximum number of directory level is 8, including the root directory. Maximum number of files and

folders per disc is 448.

 The unit may not play tracks in the order of Track numbers.

 The unit plays only the audio tracks if a disc contains both audio tracks and MP3 files.

 When playing a disc of 8 kbps or “VBR”, the elapsed playing time in the display window will not be

correct and also the intro play may not function properly. “VBR”: Variable Bit Rate.

Notes on creating your own CD-R or CD-RW containing MP3 files:

 To enjoy high quality sound, we recommend converting to MP3 files with a sampling frequency of 44.1

kHz and a fixed bit rate o f 128 kbps.

 Do not store more than 448 MP3 files per disc.

 For ISO 9660 - compliant format, the maximum allowable depth of nested folders is 8, including the root

directory (folder).

 When CD-R disc is used, playback is possible only for discs, which have been finalized.
