The JSR655 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 our 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 com-
ing from all around us are called
surround-sounds.

In order to recreate with as much
precision as possible that 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 come
from in front and in back, from left
and right.

The sound from a TV equipped with
a single speaker (or 2 speakers with
stereo televisions) sounds very differ-
ent from the actual, “live” sound.

Hall mode works best for recorded
concerts and other music programs.
In this mode, the front speakers pro-
vide a normal stereo effect while the
rear speakers provide a reverberated
sound. This reverberation helps simu-
late the sound you might hear at a
live concert.

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 speakers) than that
of ordinary stereo regeneration.

A great number of movies made in
recent times have the soundtrack
specially encoded with the Dolby
Surround mode (carrying the Dolby
Stereo or Dolby Surround trademark).
The front speakers provide the dia-
logue and the normal stereo effect,
while the rear speakers reproduce the
surround signals. This position pro-
vides excellent results when watching
television programs, video software,
video discs or videotapes of stereo
television broadcasts encoded with
Dolby Surround. Dolby Stereo films
have dramatically changed the role of
the moviegoer from that of observer to
that of participant. Clearer dialogue,

richer music, enveloping ambience
on-screen, and making high-fidelity
multidimensional sound are essential
parts of cinematic presentations.
Imagine recreating the same sort of
audio-visual experience right in your
own home.

The JSR655 incorporates a decoder
which reproduces the specially
encoded surround-sound of Dolby
Surround video programs. In Dolby
Surround mode, select the speaker
operation mode according to your
speaker system.

Select this mode if you use a small center speaker. The bass
sound of the center channel is output from the front speakers,
as a small speaker can’t produce enough bass.
