Customizing Sound Fields
By adjusting the surround parameters and the equalizer
of the front, center, surround and surround back speakers,
you can customize the sound fields to suit your particular
listening situation.
Once you customize a sound field, the changes are stored
in memory indefinitely. You can change a customized
sound field any time by making new adjustments to the
parameters.
See the table on pages 39 – 43 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 on page 19
before you customize a sound field.
Adjusting the surround parameters
The SURR 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.

Pro Logic (PRO LOGIC)
Initial setting : AUTO
Lets you specify the Pro Logic decoding setting.
• When set to “AUTO”, the receiver performs PRO
LOGIC decoding if Dolby surround encoded flag is ON
or if Pro Logic decoding produces a better sound field.
• When set to “ON”, the receiver performs PRO LOGIC
decoding on surround signals, regardless of the Dolby
surround encoded flag.
• When set to “OFF”, the receiver does not perform PRO
LOGIC decoding.
Note
Pro Logic decoding does not function for MPEG format signals.
Effect level (EFFECT)
Initial setting : (depends on sound mode)
Lets you adjust the “presence” of the current surround
effect.
Wall type (WALL S_I_H)
Initial setting : Midpoint
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 S_I_L)
Initial setting : Midpoint
Lets you control the spacing of the early reflections to
simulate a sonically longer (L) or shorter (S) room. The
midpoint designates a standard room with no adjustment.
Front reverberation (FRONT REVERB)
Initial setting : STD
This parameter can be used when “DIGITAL CONCERT
HALL A, B” is selected. This parameter lets you adjust the
amount of reverberations to add to the front signals
according to the original reverberations in the source.
• To increase front reverberations, select “WET”.
• To decrease front reverberations, select “DRY”.
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. “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.
