By adjusting the surround parameters and the tone
characteristics of the front 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 (unless the receiver is unplugged
for about two weeks). You can change a customized
sound field any time by making new adjusmmnts to the
parameters.
See the table on page 33 for the parameters available in
each sound field.
Position your speakers and do the procedures described
in "Multi Channel Surround Setup" starting on page 15
before you customize a sound field.
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.
1
Start playing a program source encoded with multi
channel surround sound.
2 Press SURR.
The button lights up and the first parameter is
displayed.

The setting is stored automatically.
Effect level (EFFECT)
Initial setting : (depends on sotmd field mode)
This parameter lets you adjust the "presence" of the
current surround effect.
Wall type
Initial setting : WALL MID
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 affect
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 wall type can be adjusted from WALL S. 1 - WALL
S. 8 (soft) to WALL H. 1 - WALL H. 8 (hard) in 17 steps.
• The midpoint WALL MID designates a nAutral wall
(made of wood).
Reverberation
Initial setting : REVB. MID
Before sound reaches our ears, it is reflected
(reverberated) many times between the 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 from REVB. S.
1 _ REVB. S. 8 (short) to REVB. L. 1 _ REVB. L. 8 (long)
in 17 steps.
• The midpoint REVB. MID designates a standard room
with no adjustment.
