16-bit 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 WMP12. FLAC files will not play on systems running Windows Media Player 11.

Some alternative UPnP server programs such as TVersity may also detect and stream FLAC files but we cannot offer support for UPnP programs beyond Windows Media Player.

Please note that 192/24 FLAC files are not Windows Media Player compatible and will not stream.

Streaming large files recorded in FLAC or WAV may be slow via a wireless connection, and particularly slow if the signal strength of the radio is less than 50%. Check your wireless strength by going to Network>Settings>Wi-Fi Strength.

24-bit FLAC files can only be played using the Aux inputs on the back panel of the unit. Not all computer soundcards will stream 24-bit audio so please confirm that the soundcard on your computer will support this resolution before trying this.

Alternatively, on Rotel products with a front USB input, you can play FLAC files from an iPod/iPhone connected to the front USB input, if that phone has an app that will play back FLAC files.
