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.

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).
TEST TONE
A test sound is generated allowing the listener to balance volume from
each channel. Adjust the volume levels until all channels are equal.
