USB MP3/WMA Overview

Note on Mp3
MP3 is short for MPEG Audio Layer 3 and
refers to an audio compression technology
standard.
This product allows playback of MP3 files on CD-
ROM, CD-R or CD-RW discs.
The unit can read MP3 files written in the format
compliant with ISO 9660. However it does not sup-
port the MP3 data written by the method of packet
write.
The unit can not read an Mp3 file that has a file
extension other than ".mp3".
If you play a non- MP3 file that has the " .mp3
" extension, you may hear some noise.
In this manual, we refer to what are called
"MP3 file" and "folder " in PC terminology as
"track" and "Album," respectively.
Maximum number of directory level is 8, inclu-
ding the root directory. Maximum number of
files and folders per disc is 256.
The unit may not play tracks in the order of
Track numbers.
The unit plays only the audio Tracks if a disc
contains both audio tracks and MP3 files.
When playing a disc of 8kbps or VBR
elapsed playing time in the display window will
not be correct and also the intro play may not
function properly.

Note on creating your own CD-Rs or
CD-RWs containing MP3 files
To enjoy high quality sound, we recommend
converting to MP3 files with a sampling fre-
quency of 44.1 kHz and a fixed bit rate of 128
kbps.
DO NOT store more than 256 MP3 files per
disc.
For ISO 9660 -compliant format, the maximum
allowable depth of nested folders is 8, inclu-
ding the root directory (folder).
When CD-R disc is used, playback is possible
only for discs which have been finalized.
Make sure that when MP3 CD-R or CDRW is
burned that it is formatted as a data disc and
NOT as an audio disc.
You should not write non-MP3 files or unnee-
ded folders along with MP3 files on the disc
otherwise it takes a long time until the unit
starts to play MP3 files.
With some CD-R or CD-RW media, data may
not be properly written depending on their
manufacturing quality . In this case, data may
not be reproduced correctly. High quality CD-
R or CD-RW disc is recommended.
Up to 16 characters are displayed for the name
of an Album or a Track. ID3 TAG version 1.x is
1
, the
required.
Note that the unit may not play Track in the
order that you wrote them to the disc.
