● MP3 and WMA playback
When a device containing MP3 or WMA files is plugged, all files in the
USB memory device are first 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 you do not write in any files other than MP3 or WMA files
or create any unnecessary folders.

Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and
WMA files, they will be mistakenly recognized and played as MP3 and
WMA files. This may result in large amounts of interference and damage
to the speakers.
● 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.
