●MP3 and WMA files
MP3 (MPEG Audio LAYER 3) is a standard audio compression format.
Files can be compressed to approximately 1 /10 of their original size using MP3
compression.
WMA (Windows Media
® Audio) is a Microsoft® audio compression format.
This format compresses audio data to a size smaller than that of the MP3 format.
There is a limit to the MP3 and WMA file standards that can be used and to the
media/formats on which the files are recorded.

●ID3 and WMA tags
ID3 tags can be added to MP3 files, making it possible to record the track title,
artist name, etc.
The system is compatible with ID3 Ver. 1.0, 1.1, and Ver. 2.2, 2.3, 2.4 ID3 tags.
(The number of characters is based on ID3 Ver. 1.0 and 1.1.)
WMA tags can be added to WMA files, making it possible to record the track
title and artist name in the same way as with ID3 tags.
●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 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 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 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 ma y not be possible at all.
