rate (less than 96 kbps, 44.1k, 48kHz) are played, the Supreme Setting function
restores their high frequencies so the sound quality is closer to files encoded
at a high bit rate. The processing is optimized for the compression format and
the bit rate used. When the Supreme Setting is Off, the unit plays the original
sound stored in the audio file.
