SOUND SYSTEM
Technical data and operating conditions
for MP3 files are as follows:
❒
adopted CD-ROM shall be mastered
according to ISO9660 Standard;
❒
music files shall be renamed as “.mp3”
otherwise they cannot be played;
❒
sampling frequencies are: 44.1 kHz,
stereo (96 to 320 kbit/s) - 22.05 kHz,
mono or stereo (32 to 80 kbit/s);
❒
it is possible to play variable bit-rate
tracks (files).
IMPORTANT Characters: blank, ‘ (apos-
trophe), ( and ) (open and closed brack-
ets) are not admitted in MP3 track names.
When sampling MP3 CD you must not
use these characters to name files other-
wise the sound system will not be able to
play it.
DIRECTORY NAME DISPLAY
The MP3 directory name shown on the
display corresponds to the name with
which the directory is stored on the CD,
followed by an asterisk.
Example of full MP3 directory name:
“BEST OF *”.
TRACK NAME DISPLAY
MP3 track can be named with the follow-
ing two procedures:
❒
if the track selected has ID3-TAG, MP3
track is named as follows:
– the first part of the track name cor-
responds to the track stored in ID3-
TAG, followed by an asterisk;
– the second part of the name identi-
fies the name of the author stored in
ID3-TAG, followed by an asterisk.
❒
If the selected track has no ID3-TAG,
the track name (not named “MP3”)
corresponds to the file name with
which the track is stored in the CD, fol-
lowed by an asterisk (e.g.: “TITLE1*”).

MP3 MODE
In addition to standard audio CDs, the
sound system can also play audio files in
MP3 format. Sound system will operate as
described in the previous section (“Sound
system with Compact Disc player”) when
inserting a conventional audio CD.
For optimal playing use only top quality
CDs mastered at the as low as possible
speed.
MP3 CD files are structured by directo-
ries, with sequential lists of all directories
containing MP3 tracks (directories and
sub-directories are all brought to the same
level), directories not containing MP3
tracks cannot be selected.
