Chapter 4 Digital Sound Effects
Dolby Surround Sound
Many video tapes and laser discs available today are encoded with Dolby surround sound, which adds
theater-like sound to your viewing experience. To take advantage of Dolby surround sound, first select
the pre-programmed Dolby Surround sound field. To make the most out of the Dolby surround sound,
however, we recommend that you select the center mode and adjust the speaker volume based on your
speaker configuration. Also, if you have rear speakers, you can adjust the timing of the sound that comes
from the rear speakers (delay time).
Selecting the Center Mode
Since all speakers are different, the receiver offers you four
types of speaker configurations (Phantom, 3 Ch Logic,
Normal, Wide). To best fit your speaker system, you can
change how the sound comes from each speaker by selecting
one of-these four configurations. Once you make the
adjustments, you do not have to adjust them again unless
you change your speaker system.
Each time you press the CENTER MODE button, the
CENTER MODE is changed in the following order:
If you have a small center speaker
Select NORMAL mode.
The bass sound of the center channel is output from the
front speakers, because a small speaker cannot produce
enough bass.
■ PHANTOM ■> 3 CH LCX31C -> NORMAL ■> WIDE
□
If you do not have a center speaker
Select PHANTOM mode.
The sound of the center channel is output from the front
speakers.
Front speaker (L) Front speaker(R)
If you have a medium to large center speaker
* Select WIDE mode.
This is the best possible combination of the speakers.
Rear speaker(L) Rear speaker(R)
If you have only front speakers and a center
speaker
^ Select 3 CH (Channel) LOGIC mode.
The sound of the rear channel is output from the front
speakers.
Note
The Dolby Pro Logic Surround Decoder is a system to
decode the software carrying the
Imark.
