Every day, we are exposed to sounds coming from our
)
surroundings. Some sounds reach our ears directly from
the source, some indirectly reflected off of walls or the
ceiling. Sounds of voices reach us from behind, sounds
of cars reach us from the side.
Sounds coming from all
around us are called "surround-sounds".
In order to recreate with as much precision as possible,
that special sound heard in movie theaters, speakers are
placed both in front of and behind the listeners. The
reason that sound from the television in our homes
is
so
different from the sound in movie theaters is because
sound from a television only comes from in front of
the viewer. With a surround system, the spatial infor-
mation encoded in a film's sound track will be repro-
duced in the home listening area.
The sound from
a
TV equipped with a single speaker (or
two speakers with stereo televisions) sounds very dif-
ferent from the actual, "live" sound.
The AVC20 is equipped with three types of surround
processors to recreate that sense of presence and let you
enjoy surround-sound in the privacy of your own home.

DOLBY SURROUND*
Provides the optimal sound when watching recent movies,
especially those encoded with the DOLBY SURROUND
or DOLBY STEREO process. The front speakers provide
the normal stereo effect, while the rear speakers reproduce
the surround signals. This position provides excellent
results when watching television programs, video soft-
ware, video discs, or videotapes of stereo television broad-
casts.
CONCERT SURROUND
This provides the best results when watching old movies
or video recordings of concerts. The front speakers provide
the normal stereo effect, while the rear speakers provide
reverberation like that heard in concert halls. The reverbe-
ration time can be adjusted using the CONCERT
SURROUND Control.
SPATIAL SURROUND
Use this when watching live sports games to reproduce that
stadium feeling.
