Pro Logic

is an
encode/decode process by
which four channels of sound-
track information are encoded
into two channels for playback
on VCRs, laser disc players,
and some TV broadcasts, and
then decoded back into four
channels for playback through
five loudspeakers. Remember
that a Dolby Pro Logic system
consists of three channels of
information for front left,
center, and right speakers and
one channel of mono surround
information. The surround
channel is played back
through two speakers. Dolby
Pro Logic helps to re-create all
of the impact and excitement
of a movie theater in your
home.
To switch between the three
surround modes: Push
“Surround Mode” on The
Source or
the remote control. If you are listening to a pro-
gram in the Dolby Pro Logic
Normal or Phantom mode
and you wish to turn off the
surround speakers:
Push “Rear Speakers” on
The Source.
