Notes On Playing Mp3 Files - Kenwood KDC-MP6090R Instruction Manual

Notes on playing MP3 files

This unit can play MP3 files.
Note, however, that the MP3 file recording media and formats
acceptable are limited.
When writing MP3 files, pay attention to the following
restrictions.
Acceptable media
The MP3 file recording media acceptable to this unit are CD-ROM,
CD-R, and CD-RW.
Acceptable medium formats
The medium formats acceptable to this unit are ISO 9660 Level 1
and Level 2 excluding the extended formats. When reading an MP3
file written in a format other than ISO 9660 Level 1 or Level 2, the
unit may fail to play the file normally or display the file or folder name
correctly.
The major specifications of ISO 9660 Level 1 and Level 2 are as
follows:
• Maximum number of directory levels: 8
• Maximum number of files and folders per directory level:
• Characters available to file and folder names:
• Maximum number of characters in file names :
Level 1: 12 (including a separator "." and a 3-character extension)
Level 2: 31 (including a separator "." and a 3-character extension)
Settings for your MP3 encoder and CD writer
When you use your MP3 encoder to compress audio data to an MP3
file, set the transfer bit rate of the
encoder to fixed 128 kbps.
When you use your CD writer to record
MP3 files up to the maximum disc
capacity, disable additional writing. For
recording on an empty disk up to the
maximum capacity at once, check Disc
at Once.
Entering ID3 tag
Displayable ID3 tag is ID3 version 1 and
1.1; the character code is ASCII (see A
List of Codes).

Entering file and folder names
When entering file and folder names, use the alphanumeric
characters described above only. 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 files which have the
MP3 filename extension (.MP3). MP3 files should therefore be saved
with the MP3 extension.
Writing files into a medium
When a medium containing MP3 data is loaded, the unit checks all
the files on the medium. If the medium contains a lot of folders or
non-MP3 files, therefore, it takes a long time until the unit starts
playing MP3 files.
In addition, it may take time for the unit to move to the next MP3 file
or a file search or folder search may not be performed smoothly.
You should not write non-MP3 files or unneeded folders along with
MP3 files on the medium.
2CAUTION
When playing MP3 files on a medium which also contains non-MP3
files or folders, observe the following precautions. Loading such a
medium may produce loud noise to break the speakers.
• Do no attempt to play a medium containing a non-MP3 file with the
MP3 extension.
The unit mistakes non-MP3 files for MP3 files as long as they have
the MP3 extension.
• Do not attempt to play a medium containing non MP3 file.
MP3 file 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 to be recorded does not
match the order in which they are played. You may be able to set the
order in which MP3 files 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.
