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 256.

∙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-Rs or CD-RWs 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 of 128 kbps.

∙DO NOT store more than 256 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.

∙Make sure that when MP3 CD-R or CD-RW is burned that it is formatted as a data disc and NOT as an audio disc.

∙You should not write non-MP3 files or unneeded folders along with MP3 files on the disc otherwise it takes a long time until the unit starts to play MP3 files.

∙With some CD-R or CD-RW media, data may not be properly written depending on their manufacturing quality. In this case, data may not be reproduced correctly. High quality CD-R or CD-RW disc is recommended.
