3-2. Using the audio system
●MP3 and WMA playback
• When a device containing MP3 or WMA files is connected, all files in the
USB memory 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 recom-
mend that you do not include any file s other than MP3 or WMA files or cre-
ate any unnecessary folders.
• When the USB memory is connected an d the audio source is changed to
USB memory mode, the USB memory 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 memory 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.
