●MP3 and WMA files
MP3 (MPEG Audio LAYER 3) is a standard audio compression format.

compression.
WMA (Windows Media

This format compresses audio data to a size smaller than that of the MP3 format.

●MP3 and WMA playback
• When a device containing MP3 or WMA files is connected, all files in the USB memory device are checked. Once the file check is finished, the first
MP3 or WMA file is played. To make the file check finish more quickly, we
recommend that you do not include any files other than MP3 or WMA files
or create any unnecessary folders.
• When the USB device is connected an d the audio source is changed to
USB memory player mode, the USB device will start playing the first file in
the first folder. If the same device is removed and reinserted (and the con-
tents have not been changed), the USB device will resume play from the
same point in which it was last used.
●Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and WMA
files, they will be skipped (not played).
●Playback
• To play MP3 files with steady sound quality, we recommend a fixed bit rate of at least 128 kbps and a sampling frequency of 44.1 kHz.
• There is a wide variety of freeware and other encoding software for MP3 and WMA files on the market, and depending on the status of the encoding
and the file format, poor sound quality or noise at the start of playback may
result. In some cases, playback may not be possible at all.
