THEATER
I DOLBY PRO LOGIC I
Dolby Pro Logic provides
four separate sound channels: left, center, right, and surround. For properly
encoded programs
marked
DI3_
the center sound channel contains the dialogue
for the program viewed.
The left and right channels
produce sound effects that will match the action on the TV screen. For example,
Dolby Pro Logic will enhance the effect of
a car viewed driving from the left side of the TV screen to the right side. The surround
channel (speakers)
are placed behind
the viewing area to add additional
spatial sound effects.
To fully benefit from Dolby Pro Logic Surround, it is recommended
that the surround speaker system be complete as shown
on page 20.
