MP3 / WMA CD Mode
The DDR-43 Plus is able to play CD-R and CD-RW discs containing
MP3 and WMA files. It is assumed in this section that a file is
equivalent to a CD track.
An MP3 / WMA CD may not contain more than 511 files and not more
than 99 folders. MP3 and WMA files should be created with an audio
sample rate of 44.1kHz (this is normal for files created from CD
audio content). MP3 and WMA data rates up to 320 kilobits per second
are supported. WMA Lossless files are not supported. The unit will not
play files which include digital rights management (DRM) protection.
When burning CD-R and CD-RW discs with audio files,
various problems may arise which could lead to problems
with playback. Typically such problems are caused by poor CD writing
or audio encoding software, or by the hardware settings of the PC’s
CD writer, or by the CD being used. Should such problems arise,
contact the customer services of your CD writer or software
manufacturer or look in their product documentation for
relevant information. When you are making audio CDs, take care to
observe all legal guidelines and ensure that the copyright of third parties
is not infringed.
1. To select the CD mode press the Media button until “CD” shows on
the display, or insert a suitably prepared CD-R or CD-RW disc.
2. Insert a CD with printed side facing up into the CD slot. The disc will
be loaded automatically. The unit will check the CD type and load its
track list. The display will show “loading” and then “reading” as the
information is read.
If there are many files or folders on the CD then it may take some
tens of seconds to read all of the file and folder names and to identify
those which are playable (with .mp3 or .wma filename extension).
