MP3/WMA OPERATION
MP3 and WMA (Windows Media Audio) music files are digital audio files that are compressed
to allow more files on a single CD. This unit can play MP3/WMA directly from files contained on
a CD-R/RW using the buttons on the receiver (or optional remote) as described below. Many
types of software are available for converting audio files into MP3/WMA formats. Jensen
recommends Nero, MusicMatch Jukebox or Roxio Easy CD Creator. Depending on the media
type and recording method, some CD-R/RW's may be incompatible with this unit. The unit
supports playback of MP3/WMA and CDDA (CDA), Mixed-Mode CDs and CD-Extra (including
multi-session discs), but discs on which the session has not been closed will not play.
Notes on MP3/WMA Play
This unit can play MP3 (MPEG1, 2, 2.5 Audio Layer 3). However, the MP3 recording media
and accepted formats 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, use full format rather than 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 name including the delimiter (".") and three-character extension are
indicated in parentheses.
• ISO 9660 Level 1 (11 characters)
• ISO 9660 Level 2 (31 characters)
• Joliet (31 characters)
• Romeo (31 characters)
Up to 200 characters can be displayed in the long file name format. 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 nested folders: 8
• Maximum number of files per disc: 999
• Maximum number of folders per disc: 255
MP3/WMA written in formats other than those listed above will not play successfully and their
file names or folder names will not be display properly.
MP3/WMA Encoder and CD Writer Settings
Use the following settings when compressing audio data in MP3 data with the MP3 encoder.
• Transfer bit rate : 8 - 320 kbps
• Sampling frequency : 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48 kHz
When using a CD writer to record MP3/WMA up to the maximum disc capacity, disable
additional writing. To record an empty disc up to the maximum capacity at once, select the
“disc at once” option.
Entering ID3 Tag
This unit supports ID3 tag versions 1.0 and 1.1.
For the character codes, refer to the table to the
right. The unit also supports CD-TEXT encoded
discs for Album, Track and Artist Title
information.
Entering File and Folder Names
Names using the code list characters are the only
file names and folder names that can be entered
and displayed. Using any other character will
cause the file and folder names to be displayed
incorrectly. The unit recognizes and plays only
files with the MP3/WMA extension.
NOTE: A file 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 data. If the medium
contains many folders or non-MP3/WMA files, MP3/WMA play will be delayed, it may take time
for the unit to move to the next file, and searches may not be performed smoothly. Loading
such a medium may produce loud noise and cause damage to the speakers. Do not attempt
to play a medium containing a non-MP3/WMA file with the MP3/WMA extension or a
medium containing non MP3/WMA files.
Electronic Shock Protection
• 40 seconds for CDDA (CDA)
• 120 seconds for MP3 recorded at 44.1kHz, 128kbps
• 200 seconds for WMA recorded at 44.1kHz, 128kbps
Bit Rates
The unit supports bit rates from 32 - 320 kbps.
MP3 Playing Order
When selected for play, files and folders (Folder Search, File Search or Folder Select) are
accessed in the order they were written by the CD writer. As a result, 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".
