Customizing Sound Fields - Sony ST-RDE945 Operating Instructions Manual

Customizing Sound Fields

By adjusting the surround parameters and the
equalization of the front, rear and center speakers, you
can customize the sound fields to suit your particular
listening situation.
Once you customize a sound field, the changes are stored
in the memory indefinitely (unless the receiver is
unplugged for about two weeks). You can change a
customized sound field any time by making new
adjustments to the parameters.
See the table on page 41 for the parameters available in
each sound field.
To get the most from multi channel
surround sound
Position your speakers and do the procedures described
in "Multi Channel Surround Setup" starting from page 19
before you customize a sound field.
Adjusting the surround parameters
The SUR menu contains parameters that let you
customize various aspects of the current sound field. The
settings available in this menu are stored individually for
each sound field.

or ) to select the
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. This
parameter lets you control the level of the high
frequencies to alter the sonic character of your 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 longer (L) or
shorter (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 EX. A, B, C sound fields off or on.
