· MP3 is short for MPEG Audio Layer 3 and refers to an audio compression
technology standard.
· This product allows playback of MP3 files on CD-ROM, CD-R or CD-RW discs.
· The unit can read MP3 files written in the format compliant with ISO 9660.
However it does not support the MP3 data written by the method of packet write.
· The unit can not read an MP3 file that has a file extension other than “.mp3”
· If you play a non- MP3 file that has the “.mp3” extension, you may hear some
noise.
· In this manual, we refer to what are called “MP3 file” and “ folder” in PC
terminology as “ track ” and “ album ”, respectively.
· Maximum number of directory level is 8, including the root directory. Maximum
number of files and folders per disc is 256.
· The unit may not play tracks in the order of Track numbers.
· The unit plays only the audio tracks if a disc contains both audio tracks and
MP3 files.
· When playing a disc of 8 kbps or “VBR”, the elapsed playing time in the display
window will not be correct and also the intro play may not function properly.
“ VBR ”:Variable Bit Rate.
· The unit supports the playback of WMA files. The playback of ID3 tags for WMA
format is not guaranteed, it depends on versions and availability of Cyrillic
alphabet.
· WMA (Windows Media Audio) -music data compression format, created by
Microsoft Corporation. This format uses coding algorithm for compression of
initial audio-record, greatly decreasing the file size, but, saving the good sound
quality even when the bit rate is low (for example, 64 Kbit/s).
· Remember that the unit may not play the tracks in order they are written on disc.
Notes on creating your own CD-R or CD-RW containing MP3 files:
·
To enjoy high quality sound, we recommend converting to MP3 files with a
sampling frequency of 44.1 kHz and a fixed bit rate o f 128 kbps.
·
DO NOT store more than 256 MP3 files per disc.
·
For ISO 9660 - compliant format, the maximum allowable depth of nested
folders is 8, including the root directory (folder).
·
When CD-R disc is used, playback is possible only for discs, which have been
finalized.
·
Make sure that when MP3 CD-R or CD-RW is burned that it is formatted as a
data disc and NOT as an audio disc.
·
You should not write non-MP3 files or unneeded folders along with MP3 files
on the disc otherwise it takes a long time until the unit starts to play MP3 files.
·
With some CD-R or CD-RW media, data may not be properly written depending
on its manufacturing quality. In this case, data may not be reproduced correctly.
High quality CD-R or CD-RW disc is recommended.
·
Up to 16 characters are displayed for the name of an Album or a Track. ID3TAG
version 1.x is required.
·
Note that the unit may not play Tracks in the order that you wrote them to the
disc.
