PLAYING AN MP3 COMPILATION
Insert an MP3 compilation in the player.
The audio equipment searches for all of the music tracks, which
may take anything between a few seconds and several tens of
seconds, before play begins.
On a single disc, the CD player can read up to 255 MP3 fi les
spread over 8 folder levels. However, it is advisable to keep to
a limit of two levels to reduce the access time before the CD is
played.
While the CD is being played, the folder structure is not followed.
All of the fi les are displayed on a single level.
To play a disc which has already

INFORMATION AND ADVICE
The MP3 format, an abbreviation of MPEG 1.2 & 2.5 Audio Layer 3,
is an audio compression standard which permits the recording of
several tens of music fi les on a single disc.
In order to be able to play a recorded CDR or CDRW, when
recording, the ISO 9660 level 1.2 or Joliet fi le format is
recommended.
If the disc is recorded in another format, it may not be played
correctly.
It is recommended that the same recording format is always used
for an individual disc, with as low a speed as possible
(4x maximum) for optimum sound quality.
SOURCE
In the particular case of a multi-session CD, the Joliet format is
recommended.
The audio system will only play fi les with the extension ".mp3" with
a sampling rate of 22.05 KHz or 44.1 KHz. No other type of fi le
(.wma, .mp4, .m3u...) can be played.
It is advisable to restrict fi le names to 20 characters without using
special characters (e.g. " ? ; ù) to avoid any playing or displaying
problems.
Empty CDs are not recognised and may damage the system.
