CD, USB
Information and advice
The audio system will only play files with
extension ".mp3" or ".wma" and a compression
rate that is constant or variable between
32 Kbps and 320 Kbps.
It is advisable to restrict file names to
20 characters without using special characters
(e.g. " ? ; ù) to avoid any playing or displaying
problems.
Use only USB memory sticks formatted FAT32
(File Allocation Table).
The playlists accepted are types .m3u and .pls.
The number of files is limited to 5 000 in
500 directories on a maximum of 8 levels.
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 an individual 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.
Do not connect a hard disk or USB
device other than audio players to the
USB port. This may cause damage to
your installation.
On a single disc, the CD player can
read up to 255 MP3 files spread
over 8 directory levels. However, it
is recommended that this be kept to
2 levels so as to limit the time taken to
access and play the CD.
During play, the folder structure is not
observed.
