Sony CDP-CX455 Primary Operating Instructions Manual page 4

Notes
• With formats other than ISO 9660 level 1, folder names or
file names may not be displayed correctly.
• When naming, be sure to add the file extension ".MP3" to
the file name.
• If you up the extension ".MP3" to a file other than MP3, the
unit cannot recognize the file properly and will generate
random noise that could damage your speakers.
• The following discs take a longer time to start playback.
– a disc recorded with complicated tree structure.
– a disc recorded in Multi Session.
– a disc to which data can be added (non-finalized disc).
Cautions when playing a disc that is recorded in Multi
Session
CD-DA (audio) data or MP3 files stored on a Multi Session
CD may be subject to some restrictions on playback.
– If the disc begins with a CD-DA session, it is recognized
as a CD-DA (audio) disc, and playback continues until an
MP3 session is encountered.
– If the disc begins with an MP3 session, it is recognized as
an MP3 disc, and playback continues until a CD-DA
(audio) session is encountered.
– The playback range of an MP3 disc is determined by the
tree structure of files produced by analyzing of the disc.
– A disc with a mixed CD format will be recognized as a
CD-DA (audio) disc.

follows:

3
5
6
6
7

Tree 1 Tree 2 Tree 3
Notes
• A folder that does not include an MP3 file is skipped.
• When you insert a disc with many trees, it takes a longer
time to start playback.
We recommend that you make only one or two trees for
each disc.
• Maximum folder number: 150 (including root folder and
empty folders)
• Maximum total number of MP3 files and folders: 300
• The CD player can play the MP3 files in a folder whose
depth in the folder tree is up to 8.
Tip
To specify a desired playback order, before the folder or file
name, input the order by number (e.g., "01", "02"), then
record contents onto a disc. (The order differs depending on
the writing software.)
Note on playback of MP3 files
Depending on the encoding/writing software, recording
device, or the recording media used at the time an MP3 file is
recorded, you may encounter such problems as disabled
playback, sound interruptions, and noise.
