About the RESTORER function
• Such compressed audio formats as MP3, WMA (Windows Media
Audio) and MPEG-4 AAC reduce the amount of data by eliminating
signal components that are hard for the human ear to hear. The
RESTORER function generates the signals eliminated upon
compression, restoring the sound to conditions near those of the
original sound before compression. It also corrects the sense of
volume of the bass to obtain richer sound with compressed audio
signals.
• This is displayed on the "Surround Parameter" and can be set
when the input source is selected to "SIRIUS" or analog signals
(including FM/AM signals) or PCM signals (fs = 44.1/48 kHz) are
input.

For details on adjusting individual parameters, see "Adjusting the parameters" (vpage 33).
