This player allows you to play MP3 fi les recorded on CD-ROMs, CD-Rs
(Recordable) and CD-RWs (Rewritable).
What is MP3?
MP3, short for MPEG-1 Audio Layer 3, MPEG-2 Audio Layer 3 LSF (Low Sampling Frequency), is a standard
for compressing digital video data adopted for video CDs and similar media. It is one of the audio compression
systems covered by MPEG’s (Motion Picture Experts Group) digital audio compression standards. What it
does is reduce the number of bytes in a song without detracting from the sound quality by eliminating big
sound waves within the sound range that is imperceptible to the human ear. This compression allows you to
reduce the contents of a conventional music CD by a factor of around 10. This means that you can record the
contents of 10 music CDs on a single CD-R or CD-RW. (The fi gures refer to data recorded on a 650 MB CD-R
or CD-RW at a fi xed bit rate of 128 kbps and a sampling frequency of 44.1 kHz.)
Points to Remember When Recording an MP3 Disc
Converting (encoding) audio data to an MP3 fi le
≥
It is recommended that you set the bit rate to “128 kbps or more” and “Fixed”.
≥
Bit rate 8 kbps of MPEG-2 and sampling frequency 16 kHz of MPEG-2 can not be reproduced.
≥
VBR (Variable Bit Rate) is not supported.
≥
The playback sound quality differs depending on the encoding software and the bit rate. For details refer to
the user manual of your encoding software.
Recording MP3 fi les on a CD-R/RW
≥
Do not record fi les other than MP3s or unnecessary folders on a disc.
If many folders or fi les other than
MP3s are recorded on a disc, it may take some time before playback starts.
≥
Use ISO 9660 fi le system (Extension of the ISO 9660 fi le systems are included.) (page 63). APPLE HFS
fi le system is not supported.
If they do not conform to ISO 9660 fi le system, the fi le may not play normally,
or the fi le or folder names may not be displayed correctly.
≥
Make sure to add the “.mp3” extension to each MP3 fi le name.
A fi le with a different fi le name extension
or none at all will not play.
≥
Although Multi session recording is supported, the use of Disc-at-Once is recommended.
Make sure to
close the session when you fi nished recording on a disc.
≥
A disc recorded by the packet writing software are not supported.
≥
A playlist function is not supported.
Record fi les and folders in the order in which you want them to be played.
Some writing software lets you specify the recording order by adding a prefi x in the range of “01”
j
“99”, etc.
to the fi le name. For details refer to the user manual of your writing software.
Note:
≥
You may encounter trouble in playing MP3s or displaying the information of MP3 fi les recorded with certain
writing softwares or CD recorders (CD-R/RW drives).
≥
If a disc contains both MP3 and CD-DA, only CD-DA data is reproduced properly. (MP3 fi les are played but
no sound is output.)
Caution:
≥
Do not assign the “.mp3” fi le name extension to a fi le that is not in the MP3 format. This may
produce noise from the speakers and cause speaker damage and can damage your hearing.
Folder selection order/MP3 fi le playback order (Example)
Note:
≥
This unit counts the number of folders
irrespective of the presence or absence of MP3
fi le.
≥
If the selected folder does not contain any
MP3 fi les, the nearest MP3 fi les in the order of
playback will be played.
≥
Playback order may be different from other
MP3 players even if the same disc is used.
≥
“ROOT” appears when displaying the root
folder’s folder name.
Maximum number of fi les/folders
≥
Maximum number of trees: 8
≥
Maximum number of folders: 254 (Root folder is not included.)
≥
Maximum number of fi les: 512
Note:
If the number of fi les and folders exceeds the number mentioned above, successful playback may not be
performed.
Supported fi le systems and fi le names
Supported fi le system
Displayable folder names and fi le names
ISO 9660 Level 1/Level 2
Name fi les and folders in accordance with the standard of each fi le system.
Refer to the instructions of writing software for details.
≥
The unit recognizes only ASCII character set. Chinese characters,
accented French characters and accented Spanish characters will be
converted into an asterisk.
