About “MP3”

What is the MP3?

MP3 (MPEG 1 Audio Layer-3) is a standard technology and format for compressing a sound sequence. The file is compressed to about 1/10 of its original size. Sounds outside the range of human hearing are compressed while the sounds we can hear are not compressed.

Playable “MP3” files on this

player

You can only play MP3 files recorded by following requirements.

USABLE MEDIA

CD-Rs and CD-RWs

USABLE DISC FORMAT

You can use ISO 9660 Level 1, Level 2 and Joliet extension format discs. In some cases, MP3 files that are recorded in a format other than these formats may not play normally or the file and folder names may not be displayed correctly.

The major specifications of the usable disc format are as follows:

•Maximum directory steps: 8

•Usable characters for a file/folder name: A - Z, a - z, 0 - 9, _ (underscore)

•Maximum number of characters for a file name: 64 including quotation marks and a 3-character extension code

Notes

•When naming, be sure to add the file extension “mp3” to the file name.

•If you put the extension “mp3” to a file other than an MP3 file, the player cannot recognize the file properly and will generate random noise that could damage your speakers.

•The file name does not correspond to the ID tag.

THE USABLE NUMBER OF FOLDERS/FILES

•Maximum folder number: 255

•Maximum file number: 255

SETTINGS FOR COMPRESSION SOFTWARE AND WRITING SOFTWARE

•To compress a source for an MP3 file, we recommend setting the transfer bit rate of the compression software to “44.1 kHz”, “128 kbps”, and “Constant Bit Rate”.

•To record up to the maximum capacity, set to the “halting of writing”.

•To record at one time up to the maximum capacity on media that has nothing recorded it, set to “Disc at Once”.

NOTES FOR SAVING FILES ON THE MEDIA

When the disc is inserted, the player reads all the files on that disc. If there are many folders or non-MP3 files on the disc, it may take a long time for play to begin or for the next MP3 file to start play.

Do not save unnecessary folders or files other than MP3 ones in the disc to be used for MP3 listening.

We recommend that you do not save other types files or unnecessary folders on a disc that has MP3 files.
