¡

 High bit rate and high sampling frequency are recom-

mended for high quality sounds.

¡

 Selecting VBR (Variable Bit Rate) is not recommended 

because playing time is not displayed properly and sound 

may be skipped.

¡

 The playback sound quality differs depending on the 

encoding circumstances. For details, refer to the user 

manual of your own encoding software and writing soft-

ware.

¡

 Be sure to put an extension compatible with the format.

Compressed audio file writing

¡

 

Do not save an audio file (CD-DA file) and a com-

pressed audio file on the same disc. Failure to 

observe this may result in difficulty in playing.

¡

 If compressed audio files formatted with two or more 

types are saved on the same disc, each format shall 

have a different folder.

¡

 Do not write files other than compressed audio files.

¡

 Playability may depend on the combination of writing 

software and disc writer to be used.

¡

 This unit does not support the play list function.

¡

 Write files in a disc-at-once manner unless otherwise 

needed.

¡

 You can shorten the duration between data read and 

playback by decreasing the quantity of files or folders, 

or the depth of the hierarchy.

Supported file systems

ISO 9660 Level 1/Level 2, Apple Extension to ISO 9660, 

Joliet, Romeo

Note

: Apple HFS, UDF 1.50, Mix CD and CD Extra are 

not supported.

Maximum number of files/folders

¡

 Maximum depth of trees: 8 

¡

 Maximum number of files: 999 

¡

 Maximum number of files in one folder: 999 

¡

 Maximum number of folders: 

  256 (Root folder is included.) 

Notes

¡

 You can shorten the duration between data read and 

playback by decreasing the quantity of files or folders, 

or the depth of the hierar

chy. 

¡

 This unit counts the number of folders irrespective of 

the presence or absence of an MP3 file. 

¡

 If the selected folder does not contain any MP3 files, 

the nearest MP3 files in the order of playback will be 

played. 

¡

 Playback order may be different from other MP3 play-

ers even if the same disc is used. 

¡

 “ROOT” appears when displaying the root folder name.
