How to Play USB Audio (hidden feature) on R-4B and all RSB Sound Bars.
Last Updated 5 years ago

You can insert a USB drive into the USB port in the back of the bar and play WAV and/or FLAC audio file formats.

You can use the track controls on the IR Remote to control it.


There will be NO source LED illumination on the front panel of the sound bar in this mode.

WAV and FLAC are only supported because this mode was designed for demonstration music playback by your local dealers.
