DOLBY PRO LOGIC
The Dolby Pro Logic feature and the center and rear speakers
(standard) assure full-scale home theater sound. When playing
back laser discs or video software that have been recorded in
Dolby Surround, astonishingly realistic sound surrounds the
listener to create a new level of audio/visual entertainment.
Independent control of the four sound channels allows the listener
to enjoy the same type of sound reproduction experienced in
movie theaters. Voices are reproduced in the front and center
sound field, while ambient sounds like cars and crowds are
reproduced on all sides of the listener for an incredibly lifelike
audio/video experience. Please read the following carefully to
“tune” the system’s output to match the characteristics of your
listening space.
Check the following:
• Before using the DOLBY PRO LOGIC, adjust the proper
balance of speaker sound levels.
• Make sure the supplied speakers are properly connected and
positioned. (See page 3)
• Make sure the TV set and video unit are properly connected.
(See page 4)
• Make sure the laser disc, video tape, etc., support

The unit is equipped with a built-in test signal generator called a
noise sequencer for easy balance adjustment of all four channels.
The sequencer outputs a noise signal that “travels” from channel

from each channel.
