Customizing Sound Fields
By adjusting the surround parameters and the
equalization of the front and center speakers, you can
customize the sound fields to suit your particular
listening situation.

EFFECT LEVEL
Initial setting : (depends on sound mode)
This parameter lets you adjust the “presence” of the
current digital cinema sound surround effect.

This parameter lets you adjust the “presence” of the
current digital cinema sound surround effect.
WALL TYPE
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
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 (small, –8)

• The midpoint (0) designates a standard room with no
adjustment.
LFE (Low Frequency Effect) MIX LEVEL
Initial setting : 0 dB
This parameter lets you attenuate the level of the LFE
(Low Frequency Effect) channel output from the sub
woofer without effecting the level of the bass frequencies
sent to the sub woofer from the front, center or rear
channels via the Dolby Digital (AC-3) bass redirection
circuitry.
• The level can be adjusted in 1 dB steps from –20.0 dB to

sounds of the front, center, or rear speakers are output
from the sub woofer according to the settings made for
each speaker in the speaker setup (page 17).
