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 among the four sur-
round modes: Push the desired
“Surround Mode” on the
receiver or 

the remote.

This system contains four surround modes.
