Surround Sound
The AVI150 is equipped with 3 types
, of surround processors (Dolby Pro
Logic, Dolby 3 Stereo and HALL)
which provide a sense of presence
and expansion and let you enjoy
surround sound in your home.
Every day, we are exposed to sounds
coming from surroundings. Some
sounds reach our ears directly from the
source, some indirectly reflected by
walls or ceilings. 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 the special sound
in movie theaters, speakers are placed
both in front of and behind the
listeners. One reason that sound from
the television in our homes is so
different from sound in movie theaters
is because usually sound from a
television only comes from in front of
the viewer. With a surround system,
the sounds of applause and cheers
from the stands during a baseball
game on TV comes from the front and
back, and from the left and right.
The sound from a TV equipped with a
single speaker (or 2 speakers with
stereo television) sounds very different
Surround Sound Effects
music, enveloping ambience, and
making high-fidelity multi-dimensional
sound are essential parts of cinematic
presentations. Imagine recreating the
same sort of audio-visual experience
right in your own home.
Surround Processors
-HALL
Hall mode works best for recorded
concerts and other music programs.
In this mode, the front speakers
provide a normal stereo effect while
the rear speakers provide a
reverberated sound. This
reverberation helps simulate the
sound you might hear at a live concert.
-DOLBY 3 STEREO
Combining the front and rear signals
so that you can enjoy a regenerated
sound field which has comparatively
more presence and a more expansive
feeling from the front 3 channels (front
L, front R, center) regeneration.
-DOLBY PRO LOGIC SURROUND
A great number of movies made in
recent times have the sound track
specially encoded with the Dolby
Surround mode (carrying the (Dolby
Stereo) or (Dolby Surround)
trademark*). The front speakers
provide the dialogue and normal
stereo effect, while the rear speakers
reproduce the surround signals. This
position provides excellent results
when watching television programs,
video software, video discs or video
tapes of stereo television broadcasts
encoded with Dolby Surround. Dolby
Stereo films have dramatically
changed the role of the movie-goer
