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 th e file check finish more quickly, we
recommend that you do not include an y 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 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 depend ing 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.
