●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 and the audio source is changed to USB
memory mode, the USB device will start playing the first file in the first folder.
If the same device is removed and reinserted (and the contents 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 mistakenly recognized and played as MP3 and WMA
files. This may result in large amounts of interference and damage to the speak-
ers.
●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.
