Enjoying Surround Sound
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 pages 41~44 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 18
before you customize a sound field.
Adjusting the surround parameters
The SURROUND 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.
1Start playing a program source encoded with multi
channel surround sound.
2Press SURROUND.
The button lights up and the first parameter is
displayed.
3Press the cursor buttons ( or ) to select the
parameter you want to adjust.
4Turn the jog dial to select the setting you desire.
The setting is entered automatically.
6.1ch Matrix (6.1 MATRIX)
Initial setting : AUTO
This parameter can be used when NORMAL SURROUND
is selected. According to the setting, the receiver decodes
and downmixes the rear center signal to the rear L/R
speakers for 6.1 channel encoded sources. This parameter
lets you enjoy the appropriate surround sound from the
rear channels.
• When set to “AUTO”, the receiver performs 6.1ch
MATRIX decoding only if 6.1ch signals decode flag is
ON.
• When set to “ON”, the receiver performs 6.1ch MATRIX
decoding only if the rear signals are 2channel,
regardless of the 6.1ch decode flag.
• When set to “OFF”, the receiver does not perform 6.1ch
MATRIX decoding.
Pro Logic (PRO LOGIC)
Initial setting : AUTO
This parameter 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 rear signals, regardless of the Dolby
surround encoded flag.
• When set to “OFF”, the receiver does not perform PRO
LOGIC decoding.
Effect level (EFFECT)
Initial setting : (depends on sound mode)
This parameter lets you adjust the “presence” of the
current surround effect.
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).
