SDP-40

MODE ADJUST

OUTPUT LEVELS

Opens the OUTPUT LEVELS menu, which can be used to adjust output levels for the Main Zone audio output connectors labeled Center, Subwoofer L/R, LFE, Side L/R, and Rear L/R. Refer to page 5-32 for more information.

PANORAMA ON, OFF

Selecting the ON setting extends the front stereo image to include surround channel signals, which creates a “wraparound” effect with side wall imaging.

Note:

The PLII MUSIC listening mode PANORAMA parameter should not be confused with the separate PANORAMA listening mode.

PRE-DELAY OFF, 1 to 100ms

Adjusts delay time between the direct sound and the onset of reverberation. Higher settings make the simulated space sound larger. Because some pre-delay is inherent in all source material, it is recommended to begin with the parameter set to OFF, then make adjustments accordingly.

RE-EQUALIZER ON, OFF

Simulates high-frequency rolloffs that occur in movie theaters. When ON is selected, the SDP-40 applies a high-frequency filter. When OFF is selected, the SDP-40 does not apply a high-frequen- cy filter. It is recommended to set this parameter to ON for film sources, as many films are mixed for movie theaters and might sound too bright when played back in home theaters without re-equalization.

REAR DLY OFFSET OFF, 1 to 30ms

Increases the perceived depth of the listening space by delaying the arrival time of rear speaker signals. It is recommended to increase the setting when using side and rear speakers that are located close together or when a greater sense of depth is desired in the listening space.

REAR L/R OFF, -30 to +12dB

Controls the output level of the Main Zone audio output connectors labeled Rear L/R.

RESET MODE

Restores the factory-default version of the selected listening mode, restoring all listening mode menu parameters to their factory- default settings.

ROLLOFF 500Hz to 20.0kHz, OFF

Simulates the absorption of high frequencies in real spaces. It is rec- ommended to begin with a low setting to simulate high- frequency absorptive spaces.

SIDE L/R OFF, -30 to +12dB

Controls the output level of the Main Zone audio output connectors labeled Side L/R.
