Acceptance of the fi les
Some blank CDs may not be played
by your equipment (quality, recording
speed...).
When you burn a CD-R or CD-RW,
select the ISO 9660 level 1.2 or Joliet
burning standard.
To obtain the best acoustic quality pos-
sible, select the lowest burning speed.
The MPEG1 and MPEG2 standards
are accepted.
Transmission speeds between 32 and
320 kbits/s and scans between 16 kHz
and 48 kHz are accepted.
To display the title information (the
name of the artist, the title of the album,
etc...), the information contained in the
ID3 Tags or the WMA Tags must be in-
cluded in the MP3/WMA fi les burned
onto the disc.
What is the MP3/WMA fi le format?
MP3 is the abbreviation of MPEG-1 Audio
Layer 3 and MPG is the abbreviation of
Motion Pictures Experts Group, a digital
video data compression standard used on
media such as video CDs.
The MP3 compression reduces the
number of bytes in a song by eliminat-
ing the long sound waves in the range of
frequencies which are imperceptible to
the human ear, so producing high quality
audio fi les with a low volume of data.
This compression divides the size of
the content of a conventional audio CD
by approximately 10, which means that
the content of 10 audio CDs can be re-
corded onto a single CD-R or CD-RW.
WMA is the abbreviation of Windows
Media Audio, another audio data com-
pression standard offered by Microsoft.
It can be used to create and save audio
fi les at a compression rate higher than
that of the MP3 format.
Windows Media and Microsoft Corpo-
ration are trademarks registered in the
United States and/or other countries. When the MP3/WMA CD
is inserted in the player,
playing of the tracks is
automatic.
The tracks cannot be record-
ed onto the music server.
You can play CDs with up
to 8 levels, 255 folders and
400 fi les maximum.
