Notes on playing MP3/WMA
KDC-X679/MP6025/MP625 can play MP3 (MPEG1, 2 Audio Layer 3)/WMA. Note, however, that the MP3/ WMA recording media and formats acceptable are limited. When writing MP3/WMA, pay attention to the following restrictions.
Acceptable media
The MP3/WMA recording media acceptable to this unit are CD-ROM, CD-R, and CD-RW.
When using CD-RW, do full format not quick format to prevent malfunction.
Acceptable medium formats
The following formats are available for the media used in this unit. The maximum number of characters used for file and folder name including the delimiter (".") and three-character extension are indicated in parentheses.
•ISO 9660 Level 1 (12 characters)
•ISO 9660 Level 2 (31 characters)
•Joliet (64 character; Up to 32 characters are displayed)
•Romeo (128 character; Up to 64 characters are displayed)
•Long file name (200 characters; Up to 64
characters are displayed)
•Maximum number of characters for folder name: 64 (Joliet; Up to 32 characters are displayed)
For a list of available characters, see the instruction manual of the writing software and the section Entering file and folder names below.
The media reproducible on this unit has the following limitations:
•Maximum number of directory levels: 8
•Maximum number of files per folder: 255
•Maximum number of folders: 50 MP3/WMA written in the formats other than the
above may not be successfully played and their file names or folder names are not properly displayed.
Settings for your MP3/WMA encoder and CD writer
Do the following setting when compressing audio data in MP3/WMA data with the MP3/WMA encoder.
• Transfer bit rate: MP3: 8 —320 kbps WMA: 48 —192 kbps
• Sampling frequency
MP3: 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48 kHz WMA: 32, 44.1, 48 kHz
When you use your CD writer to record MP3/WMA up to the maximum disc capacity, disable additional writing. For recording on an empty disc up to the maximum capacity at once, check Disc at Once.
8 | English
•Play mode may not be possible when portions of the functions of Windows Media Player 9 or higher are used.
Entering ID3 tag
The Displayable ID3 tag is ID3 version 1.x.
For the character code, refer to the List of Codes.
Entering file and folder names
The code list characters are the only file names and folder names that can be entered and displayed.
If you use any other character for entry, the file and folder names are not displayed correctly. They may neither be displayed correctly depending on the CD writer used.
The unit recognizes and plays only those MP3/WMA which have the MP3/WMA extension (.MP3/.WMA).
•A file with a name entered with characters not on the code list may not play correctly.
Writing files into a medium
When a medium containing MP3/WMA data is loaded, the unit checks all the data on the medium. If the medium contains a lot of folders or non-MP3/ WMA files, therefore, it takes a long time until the unit starts playing MP3/WMA.
In addition, it may take time for the unit to move to the next MP3/WMA file or a File Search or Folder Search may not be performed smoothly.
Loading such a medium may produce loud noise to damage the speakers.
•Do no attempt to play a medium containing a non-MP3/ WMA file with the MP3/WMA extension.
The unit mistakes non-MP3/WMA files for MP3/WMA data as long as they have the MP3/WMA extension.
•Do not attempt to play a medium containing non MP3/ WMA.
MP3/WMA playing order
When selected for play, Folder Search, File Search, or for Folder Select, files and folders are accessed in the order in which they were written by the CD writer.
Because of this, the order in which they are expected to be played may not match the order in which they are actually played. You may be able to set the order in which MP3/WMA are to be played by writing them onto a medium such as a CD-R with their file names beginning with play sequence numbers such as "01" to "99", depending on your CD writer.
For example, a medium with the following folder/ file hierarchy is subject to Folder Search, File Search, or Folder Select as shown below.
