bit 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.
Volume Offset: The level of each source may be independently
