Dolby Pro Logic provides for separate sound channels: left, center, right and surround. For a properly encoded program
marked Drll eoBv=Jm=Xmo J the center 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 15.
