Media that can be played back with this
equipment
Usable media apart from audio CDs (CD-DA)
Usable media : CD-ROM, CD-R, CD-RW
Usable formats : ISO9660 level 1 and level 2 (excluding expanded formats)
Files that can be played back: MP3 and WMA files
Creating media for playing back on this
equipment
Compressing MP3 and WMA files
Please set up the transfer bit rate setting for the compression software when com-
pressing MP3 and WMA files as follows:
MP3 Files
: 128kbps recommended (32kbps-320kbps)
WMA Files
: 128kbps recommended (64kbps-160kbps)
This unit is compatible with 32kHz, 44.1kHz (recommended) and 48kHz samplimg
frequencies.
Categorizing folders
As MP3 and WMA files are compressed into high-quality sound files at an extremely
high rate of compression, it is possible to record several times more tracks than audio
CDs onto a single medium. It is therefore convenient to split the tracks into different
folders by genre, artist or album for retrieval and repeat playback purposes.
A maximum of 23 folders or a maximum of 200 files can be stored on a single media.
There are cases where it is not possible to save folders in the desired sequence
depending on the software being used.
Naming files
Single-byte characters between A and Z, single-byte numerals between 0 and 9, and
the single-byte underscore (_) can be used when naming files. A maximum of twelve
characters can be displayed. Ensure that the ".MP3" (MP3 files) or ".WMA" (WMA files)
extension logs are attached to all file names.
Never add the MP3 or WMA extension logs to any files other than MP3 and WMA
files. If the MP3 or WMA extension logs are added to any files other than MP3 and
WMA files, the equipment will assume that they can be played back, and this will
produce loud noises in the headphones, resulting in damage of adverse effects.
Hint for when naming folders and files
When media containing MP3 and WMA files are played back on this equipment, the
sequence in which each track is played back will be the same as the sequence in which
they were saved. It is possible to set up the playback sequence by adding numbers
from between 01 and 99 to the front of the folder and the file name when saving the file.
There are cases where it is not possible to save files in the desired sequence de-
pending on the software being used.
Additional information
Depending on the MP3 and WMA compression software in use, it is possible to save
track titles, artist names and other information together with each sound file as addi-
tional information.
Although it is possible to display pre-recorded title and artist information with this infor-
mation, it is necessary to ensure that this information has been entered in single-byte
alphanumericals (Up to a maximum of 30 alphanumericals for each.).
The method of entering title and artist information will differ in accordance with the
compression software. Refer to the compression software's instruction manual or
help file.
Confirming media and files
Check to ascertain that MP3 and WMA files can be played back correctly on the per-
sonal computer in use prior to saving them onto the media. Check to ensure that the
saved file can be played back normally.
It is not possible to confirm that files can be played back correctly while they are
being saved onto the media.
When saving files onto media
Ensure that the session is closed or finalized when data has been written on media.
There are cases where media on which the session has not be closed or finalized will
not be played back correctly with this equipment.
There are cases were the folder names and file names will not be displayed cor-
rectly depending on the software used to save them.
Do not store files or folders other than MP3 and WMA on media to be played back
with this equipment.
It is recommended that ten or less sessions are stored when recording MP3 and
WMA files onto a medium.
There are cases where playback is not possible when MP3 and WMA files (CD-
ROM) and music CD information (CD-DA) are saved on the same media.
