and Thomson multimedia.MP3 MODE
In addition to playing regular audio CDs,
the radio is also able to play CD-ROMs on
which audio files have been recorded us-
ing the MP3 compression format. The ra-
dio will work according to the modes de-
scribed in chapter “5” when an ordinary
audio CD is loaded.
To guarantee optimal playback quality it is
advisable to use good quality CDs mas-
tered at the lowest speed possible.
The files on an MP3 CD are structured in
folders that create lists of all the folders
containing MP3 tracks (folders or sub-
folders are all displayed on the same lev-
el); the folders that do not contain MP3
tracks cannot be selected.The specifications and operating condi-
tions for playing MP3 files are the follow-
ing:
❒the CD-ROMs used should be mas-
tered in accordance with the ISO 9660
standard;
❒the music files should have the exten-
sion “.mp3”: files with a different ex-
tension will not be reproduced;
❒The sampling frequencies that can be
reproduced are: 44.1 kHz, stereo (from
96 to 320 kbit/s) - 22.05 kHz, mono or
stereo (from 32 to 80 kbit/s);
❒tracks with a variable bit-rate can be re-
produced.
IMPORTANT The track names must not
include the following characters: spaces, ‘
(apostrophes), ( and ) (open and close
brackets). During the mastering of a MP3
CD, make sure that the names of the files
do not contain these characters; if they do,
the radio will not be able to play the tracks
involved.
