LOUDNESS ON, OFF
Controls the amount of low-frequency boost that is automatically
applied to the Main Zone audio output connectors labeled Front
L/R, Center, LFE, and Subwoofer L/R. When ON is selected, loudness
compensation is automatically applied based on volume level. As
volume level increases, the amount of low-frequency boost
automatically decreases. The loudness contour is optimized for
input sources calibrated to THX reference levels. When OFF is
selected, no loudness compensation is applied.
The graph shown at the right indicates the frequency response that
is automatically applied when the LOUDNESS parameter is set to
ON and Main Zone volume level is adjusted.
Note:
When the Shift command bank is activated, pressing
the TV button sets the LOUDNESS parameter to ON
and pressing the SAT button sets the LOUDNESS
parameter to OFF.
