DOLBY PRO LOGIC
Dolby Pro Logic provides four separate sound channels: front left, center, front right, and
surround. For properly encoded programs marked 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 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.
Press THUMB STICK or to highlight a surround function.
Use THUMB STICK to change the surround function.
The function can be set to DOLBY 3 STEREO or DOLBY PRO LOGIC. When DOLBY 3
STEREO is set, the surround channel sound is split equally between the left and right
speakers of the separate audio amplifier. When DOLBY PRO LOGIC is set, separate
surround sound speakers must be used.
Also, the function can be set to NORMAL or TV AS CENTER. When NORMAL is set, center
channel sound is sent to the TV center speakers, while left and right audio is sent to the TV's
left and right speakers. When TV AS CENTER is set, center channel sound is sent to the TV
center speakers while left and right audio si sent to the left and right speakers of a separate
audio amplifier (TV's left and right speakers are automatically turned off).
