5-5. Using an external device
● WMA file compatibility
• Compatible standards
WMA Ver. 7, 8, 9
• Compatible sampling frequencies
32, 44.1, 48 (kHz)
• Compatible bit rates (only compatible with 2-channel playback)
Ver. 7, 8: CBR 48 - 192 (kbps)
Ver. 9: CBR 48 - 320 (kbps)
● File names
The only files that can be recognized as MP3/WMA and played are those
with the extension .mp3 or .wma.
● 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 mode, the USB device will start playing the first file in the
first folder. If the same device is removed and reinserted (and the con-
tents 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 depending on the status of the encod-
ing 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.

Microsoft Corporation in the U.S.A. and other countries.
