What audio file formats are supported when playing music from a USB storage device?
The PartyBox 1000 supports MP3, WMA, and WAV file formats via USB. The USB file system must be FAT16 or FAT32. If music does not play automatically, check that your files are in one of these supported formats. (Page 11)
