L/R Audyssey Flat OFF : Optimize frequency response of speakers except front L and R speakers. : Optimize frequency response of all speakers to flat response. : Turn equalizer off. OFF Audyssey Audyssey Flat Audyssey Byp. L/R • When "Audyssey" is selected, "Audyssey MultEQ" indicator lights green. • When "Audyssey Byp. L/R" or "Audyssey Flat" is selected, or when the auto setup measuring results have changed, "Audyssey MultEQ" indicator lights red. •"Audyssey", "Audyssey Byp.

L/R" and "Audyssey Flat" cannot be selected and measurements have to be taken again to include the newly-added speakers. • When using headphones, "Room EQ" is always set to "OFF". RESTORER This function restores compressed audio signals to how they were before compression and corrects the sense of volume of the bass and treble to obtain richer playback sound. [Selectable items] OFF : Do not use RESTORER. Mode1 (RESTORER 64): Optimized mode for compressed sources with very weak highs. Mode2 (RESTORER 96): Apply suitable bass and treble boost for all compressed sources. Mode3 (RESTORER HQ): Optimized mode for compressed sources with normal highs. The default setting for "iPod" is "Mode3". All others are set to "OFF". OFF Mode 1 Mode 2 (RESTORER 64) (RESTORER 96) Mode 3 (RESTORER HQ) 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 "XM" or analog signals (including AM/FM signals) or PCM signals (fs = 44.1/48 kHz) are input. Night Mode Optimized setting for late-night listening. [Selectable items] OFF : Turn night mode off. LOW : Low setting. MID : Middle setting. HIGH : High setting. Operating from the remote control unit Press the NIGHT button. OFF LOW MID HIGH When the surround mode is set to "neural", the "RESTORER" can not be selected. 33
