10. 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).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 multisession
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.

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.

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 the formats other than the above may not be successfully played and their
file names or folder names may not be properly displayed.
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 : 32- 320 kbps
Sampling frequency : 32,44.1,48 kHz(WMA) 16,22.05,24,32,44.1, 48kHz (MP3)
When using a 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.
Entering ID3 Tag
This unit supports ID3 tag versions 1.0 and 1.1.
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.
