The RDG-1520, RT-09 and RCX-1500 will play a wide variety of popular audio file formats. Depending upon the type of connection being used, and also the software involved if streaming the audio from a UPnP server will determine which files can be played. The list below details what files will play with each connection type:

• Front Panel USB Input (w/ iPod or iPhone): AAC, AAC+, AIFF, Apple Lossless, MP3, WAV
• Front Panel USB Input (w/ USB Flash Drive): AAC, AAC+, MP3, WAV, WMA
• UPnP Streaming (Windows Media Player 11): MP3, WAV, WMA
• UPnP Streaming (Windows Media Player 12): AAC, AAC+, FLAC*, MP3, WAV, WMA
• Internet Radio: AAC, AAC+, MP3, Ogg Vorbis, WAV, WMA

TVersity, EyeConnect and other third-party UPnP software programs that support additional file types will be recognized by RDG-1520, RCX-1500 and RT-09 but we do not offer support for these programs.

*FLAC files can be streamed via the UPnP server connection, but to do so requires that they be playable on Windows Media Player 12 and this may require a third party program to make them visible to WM12. Only 16-bit FLAC files are supported.
