Supported audio file formats
This unit supports the following file formats. Note that some file formats are not available for playback although they are listed
as playable file formats. Also, the compatibility of file formats varies depending on the type of server. Check with your server to
ensure the compatibility of file formats supported by your server.
• If an attempt is made to play files with unsupported formats, the sound may be intermittent or be accompanied by noise. In
such cases, confirm that the file format is compatible with this unit.
• Internet Radio playback may be affected by the Internet communications environment, and in this case playback may not be
possible even with the file formats listed here.
• For WAV, FLAC, AIFF and Apple Lossless files, if music files with the same format, sampling frequency, quantization bitrate
and channel are queued up sequentially, gapless playback will be possible.
- If the format has been changed on the server (transcode), gapless playback will not be possible.
- Gapless playback is not possible in DMR mode.
