AV1
Mode Adjust
5-35
ROLLOFF 500Hz to 20.0kHz, OFF
Simulates the absorption of high frequencies in a real space. It is
recommended that you begin with a low setting to simulate high-
frequency absorbative spaces.
SIDE L/R OFF, -30dB to +12dB
Controls the output level of the audio output connector labeled Side
L/R.
SIZE 4m to 20m or 30m
Adjusts the length of the listening space within a 4m to 20m or
30m range (depending on the listening mode). Increase the size of
the space to increase the reverb effect.
CAUTION!
Setting the BASS RT, MID RT and SIZE parameters to a high
value may produce undesirable or damaging audio.
SOUND STAGE FRONT, NEUTRAL, REAR
Dynamically controls the relative balance of the audio output connec-
tors. When set to FRONT, Side L/R and Rear L/R output levels are atten-
uated by 6dB, shifting the perceived balance of the sound field to the
front of the listening space. When set to NEUTRAL, 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
set to REAR, 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

SPEAKER ANGLE 10deg to 90deg
See “PANORAMA CALIBRATION” on page 5-12 for more information.
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.
SUB LEVEL OFF, -30dB to +12dB
Controls the output level of the audio output connector labeled
Subwoofer. The SUB LEVEL parameter appears on listening mode
menus when the listening mode does not accommodate multi-
channel output signals.
SUBWOOFER OFF, -30dB to +12dB
Controls the output level of the audio output connector labeled
Subwoofer.
