SDP-40
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
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
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
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
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.
ON, OFF
REAR L/R
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
OFF, 1 to 100ms
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
Controls the output level of the Main Zone audio output connectors
ON, OFF
labeled Side L/R.
