parameter you want to adjust.
4 Turn the jog dial to select setting you desire. The
setting is entered automatically.
Wall type (WALL)
Initial setting : midpoint
When sound is reflected off soft material, such as a
curtain, the high frequency elements are reduced. A hard
wall is highly reflective and does not significantly effect
the frequency response of the reflected sound. Tliis
parameter lets you control the level of the high
frequencies to alter the sonic character of > our listening
environment by simulating a softer (S) or harder (H) wall.
The midpoint designates a neutral wall (made of wood).
Reverberation (REVERB)
initial setting : midpoint
Before sound reaches our ears, it is reflected
(reverberated) many times between he left and right
walls, ceiling, and floor. In a large room, sound takes more
time to bounce from one surface to another than in a
smaller room. This parameter lets you control the spacing
of the early reflections to simulate a sonically larger (L) or
smaller (S) room.
• The reverberation can be adjusted ±8 from S (short, -8)
to L (long, +8) in 17 steps.
• The midpoint (0) designates a standard room with no
adjustment.
Screen depth (SCREEN DEPTH)
Initial setting : MID
In a movie theater, sound seems to come from inside the
image reflected on the movie screen. This parameter
allows you to create the same sensation in your listening
room by shifting the sound of the front speakers "into"
the screen.
• The screen depth can be set to OFF, MID, or DEEP.
• DEEP provides the greatest amount of screen depth.
Virtual speaker (VIR. SPEAKERS)
Initial setting: ON
Allows you turn the virtual speakers created by the
CINEMA STUDIO EX. A, B, C and SEMI-CINEMA
STUDIO A, B, C sound fields off or on.
Effect level (EFFECT)
initial setting : (depends on sound mode)
This parameter lets you adjust the "presence" of the
:urrent surround effect.
