Using the Digital Surround Processor
Simulating the Wall Material
When sound is reflected by a wall made of soft materi-
al such as wood or a wall covered with a curtain, the
high frequency components are reduced. A hard wall is
highly reflective and does not significantly effect the
frequency response of the reflected sound.
The WALL parameter controls the level of high frequen-
cies to simulate the wall material. The S$ indicator in
the display signifies a soft wall, the H indicator signi-
fies a hard wall, the middle point designates the stan-
dard wall made of wood.

Simulating the Seat Position
When you sit in the front of a room, you will hear more
direct sound from the front speakers, and the compo-
nent of reflected sounds from the front speakers grows
as you move to the rear. Similarly, the component of
reflected sound changes when you move from left to
right, and vice versa. The F/R and UR parameters con-
trol the balance of the direct and reflected sound and
other components of sound to simulate your listening
position.
When adjusting the F/R parameter, the F indicator in
the display signifies the front position of the room, the
R indicator signifies the rear position, the middle point
of the indicator designates the center position. When
adjusting the L/R parameter, the L indicator signifies
the left position of the room, the R indicator signifies
the right position, and the middie point of the indicator
designates the center position.
Note
You cannot adjust the L/R parameter in the LIVE
CONCERT and THEATER mode.
