listening space. When set to REAR, the Side L/R and Rear L/R output
levels are not attenuated, preserving the intended balance of the
sound field. Available in all Logic 7 modes.
SOURCE RIGHT, LEFT & RIGHT, LEFT
Controls the perceived direction of the PANORAMA listening mode
external calibration source signal. When RIGHT is selected, the
sound is perceived to come from the right of the primary listening
position. When LEFT is selected, the sound is perceived to come
from the left of the primary listening position. When LEFT & RIGHT
is selected, the sound is perceived to come from all around the
primary listening position. Refer to the Calibration section that
begins on page 5-13 for more information about the SOURCE
parameter. Available in PANORAMA CALIBRATION.
Note:
The SOURCE parameter controls the perceived direction of the sound,
although both the front left and right speakers generate the external
calibration source signal.
SPEAKER ANGLE 10 to 90deg
Compensates for a wide or narrow speaker angle relative to the
primary listening position. Select the setting closest to the angle
between the front left and right speakers and the primary listening
position. Refer to the Calibration section that begins on page 5-13
for more information about the SPEAKER ANGLE parameter.
Available in PANORAMA CALIBRATION.
SPEECH DETECT ON, OFF
Distinguishes monaural speech from other input sources. When set to
ON, effects are lowered to minimize interference and unnatural echo
in monaural speech. When stereo input sources are present, the front
left and right channels are independently used as inputs for ambience
synthesis. When strong monaural speech is present in the input source,
the monaural component of the ambience effect is reduced and the
stereo component of the effect is increased. When set to OFF, the
amount of ambience synthesis is dynamically controlled. Available in
NIGHTCLUB, CONCERT HALL, CHURCH, and CATHEDRAL modes.
SUB L/R & SUB L/R LVL OFF, -30 to +12dB
Controls the output level of the Main Zone audio output
connectors labeled Subwoofer L/R. The SUB L/R parameter appears
on the listening mode OUTPUT LEVELS menu. The SUB L/R LVL
parameter appears on listening mode menus when the listening
mode does not accommodate multi-channel output signals.
Available in all modes.
SURR ROLLOFF 500Hz to 20.0kHz, OFF
Applies high frequency attenuation control to the audio output
connectors labeled Side L/R and Rear L/R. This filter is only applied to
output signals generated by the SDP-40HD. Available in all Logic 7,
PANORAMA, MONO LOGIC, and 5.1 MONO LOGIC modes.
SURROUND DLY 0 to 15ms
Increases the perceived depth of the listening space by delaying the
arrival time of signals from the side and rear speakers. It is
recommended that you increase the setting when a greater sense of
depth is desired in the listening space. Available in Dolby PLII MUSIC
and Dolby PLIIx MUSIC modes.
