Audio system
and AAC playback are CD-Rs and
CD-RWs.
Playback in some instances may not be
possible, depending on the status of the
CD-R or CD-RW. Playback may not be
possible or the audio may jump if the
disc is scratched or marked with finger-
prints.
●Compatible disc formats
The following disc formats can be used.
•Disc formats:
CD-ROM Mode 1 and Mode 2
CD-ROM XA Mode 2, Form 1 and Form 2
• File formats:
ISO9660 Level 1, Level 2, (Romeo, Joliet)
UDF2.01
MP3, WMA and AAC files written in any
format other than those listed above
may not play correctly, and their file
names and folder names may not be
displayed correctly.
Items related to standards and limita-
tions are as follows.
• Maximum directory hierarchy: 8 levels (including the root)
• Maximum length of folder names/file
names: 32 characters • Maximum number of folders: 192
(including the root)
• Maximum number of files per disc: 255
●File names
The only files that can be recognized as
MP3/WMA/AAC and played are those
with the extension .mp3, .wma or .m4a.
●Multi-sessions
As the audio system is compatible with
multi-sessions, it is possible to play
discs that contain MP3, WMA and AAC
files. However, only the first session can
be played.
●ID3, WMA and AAC tags
ID3 tags can be added to MP3 files,
making it possible to record the track
title, artist name, etc.
The system is compatible with ID3 Ver.
1.0, 1.1, and Ver. 2.2, 2.3 ID3 tags. (The
number of characters is based on ID3
Ver. 1.0 and 1.1.)
WMA tags can be added to WMA files,
making it possible to record the track
title and artist name in the same way as
with ID3 tags.
AAC tags can be added to AAC files,
making it possible to record the track
title and artist name in the same way as
with ID3 tags.
●MP3, WMA and AAC playback
When a disc containing MP3, WMA or
AAC files is inserted, all files on the disc
are first checked. Once the file check is
finished, the first MP3, WMA or AAC file
is played. To make the file check finish
more quickly, we recommend you do not
write in any files other than MP3, WMA
or AAC files or create any unnecessary
folders.
If the discs contain a mixture of music
data and MP3, WMA or AAC format
data, only music data can be played.
●Extensions
If the file extensions .mp3, .wma and
.m4a. are used for files other than MP3,
WMA and AAC files, they will be mistak-
enly recognized and played as MP3,
WMA and AAC files. This may result in
large amounts of interference and dam-
age to the speakers.
●Playback • To play MP3 file with steady sound
quality, we recommend a fixed bit rate
of 128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be
possible in some instances, depend-
