INFORMATION AND ADVICE
The audio system can only play fi les with ".mp3", ".wma" or ".wav"
extensions.
A high compression level can degrade the sound quality.
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.
Playlists accepted are types .m3u and .pls.
The system can recognise up to 5 000 fi les in 500 folders on 8 levels.
308
On a given disc, the CD player can read up to 255 MP3 fi les spread
over 8 levels. However, it is advisable to keep to a limit of two levels to
reduce the access time before the CD is played.
The folder structure is not observed during playback.
In order to be able to play a recorded CDR or CDRW, when recording
it is preferable to select standards ISO 9660 level 1.2 or Joliet.
If the disc is recorded in another format, it may not be played correctly.
It is recommended that the same recording standard is always used
for a given disc, with as low a speed as possible (4x maximum) for
optimum sound quality.
In the particular case of a multi-session CD, the Joliet standard is
recommended.
