AUDIO CONTROLS TILT EQ

Controls the amount of tilt equalization applied to the audio output connectors labeled Front L/R, Center and Subwoofer. This parame- ter setting affects the entire frequency spectrum with a hinge point at 1kHz. As the setting is increased, frequencies higher than 1kHz are boosted, while frequencies lower than 1kHz are simultaneously cut. As the setting is decreased, frequencies higher than 1kHz are cut, while frequencies lower than 1kHz are simultaneously boosted. The graph on the next page illustrates the frequency response of TILT EQ parameter settings.

Note:

Pressing and holding the S2 button while pressing and releasing the Blue button sets the BASS, TREBLE, and TILT EQ parameters to +0.0dB.

LOUDNESS ON, OFF

AUDIO CONTROLS LOUDNESS

Controls the amount of low-frequency boost that is automatically applied to the audio output connectors labeled Front L/R, Center and Subwoofer. When set to ON, loudness compensation is auto- matically applied based on volume level. As volume level increases, the amount of boost automatically decreases. The loudness contour is optimized for sources calibrated to THX reference levels. When set to OFF, no loudness compensation is applied. The graph on the next page illustrates the frequency response that is automatically applied when the LOUDNESS parameter is set to ON and the vol- ume level is adjusted.

Note:

The graph on the next page displays the Loudness parameter settings between -30dB and 0dB in 1dB increments. The top- most line represents the curve at -30dB.
