Listening Mode Menu Parameter Descriptions
(continued from page 5-39)
SIZE 4 to 20 or 30m
Adjusts listening space length within a 4 to 20 or 30m range
(depending on the listening mode). Increase the size of the space
to increase the reverb effect. The full parameter range might not be
available depending on the BASS RT and MID RT parameter settings.
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 5-12
for more information about the SPEAKER ANGLE parameter.
SPEECH DETECT ON, OFF
Distinguishes monaural speech from other input sources. When
ON is selected, effects are lowered to minimize interference and
unnatural echo in monaural speech. When stereo 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 OFF is selected, the amount of ambience
synthesis is dynamically controlled.
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.
Setting the BASS RT, MID RT, or SIZE parameters to a high
value may produce undesirable or damaging audio.
CAUTION
SOUND STAGE FRONT, NEUTRAL, REAR
Dynamically controls the relative balance of the Main Zone audio
output connectors labeled Side L/R and Rear L/R. When FRONT is
selected, Side L/R and Rear L/R output levels are attenuated by 6dB,
shifting the perceived balance of the sound field to the front of the
listening space. When NEUTRAL is selected, Side L/R and Rear L/R
output levels are slightly attenuated by 3dB, shifting the perceived
balance of the sound field to the center of the listening space.
When REAR is selected, Side L/R and Rear L/R output levels are not
attenuated, preserving the intended balance of the sound field.
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 5-12
for more information about the SOURCE parameter.
