AUDIO CONTROLS LOUDNESS

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.
