About MP3 files
MP3 (MPEG 1 Audio Layer-3) is a standard
technology and format for compressing a sound
sequence. The file is compressed to about 1/10 of
its original size. Sounds outside the range of
human hearing are compressed while the sounds
we can hear are not compressed.
Notes on discs
You can play MP3 files recorded on CD-ROMs,
CD-Rs, and CD-RWs.
The disc must be in the ISO 9660*
1
level 1 or
level 2 format, or Joliet or Romeo in the
expansion format.
You can use a disc recorded in Multi Session*
2
.

1
ISO 9660 Format
The most common international standard for
the logical format of files and folders on a
CD-ROM.
There are several specification levels. In
Level 1, file names must be in the 8.3 format
(no more than 8 characters in the name, no
more than 3 characters in the extension
“.MP3”) and in capital letters. Folder names
can be no longer than 8 characters. There can
be no more than 8 nested folder levels. Level
2 specifications allow file names up to 31
characters long.
Each folder can have up to 8 trees.
For Joliet or Romeo in the expansion format,
make sure of the contents of the writing
software, etc.

Multi Session
This is a recording method that enables
adding of data using the Track-At-Once
method. Conventional CDs begin at a CD
control area called the Lead-in and end at an
area called Lead-out. A Multi Session CD is a
CD having multiple sessions, with each
segment from Lead-in to Lead-out regarded
as a single session.
CD-Extra: The format which records audio
(audio CD data) as tracks on session 1, and
records data as tracks on session 2.
Mixed CD: In this format, data is recorded as
track 1, and audio (audio CD data) is recorded
as track 2.
Notes
• With formats other than ISO 9660 level 1 and level 2,
folder names or file names may not be displayed
correctly.
• When naming, be sure to add the file extension
“.MP3” to the file name.
• If you put the extension “.MP3” to a file other than
MP3, the unit cannot recognize the file properly and
will generate random noise that could damage your
speakers.
• The following discs take a longer time to start
playback.
– a disc recorded with complicated tree structure.
– a disc recorded in Multi Session.
– a disc to which data can be added (non-finalized
disc).
Cautions when playing a disc that is recorded in
Multi Session
• When the first track of the first session is audio CD
data:
Non-audio CD data information (track number, time,
etc.) is displayed with no sound.
• When the first track of the first session is not audio
CD data:
– If an MP3 file is in the disc, only MP3 file(s) play
back and other data is skipped. (Audio CD data is
not recognized.)
– If no MP3 file is in the disc, “NO Music” is
displayed and nothing is played back. (Audio CD
data is not recognized.)
