3-4-CHANNEL STEREO SYSTEM
@ 4-CHANNEL STEREO
In the continued pursuance of more aesthetical
sound, another stereo revolution has taken
place... A new stereo “break-through” from
2-channel to 4-channel stereo,
This “move-up” to 4-channel stereo is cqually
as great an achievement as the advancement
from monaural to 2-channel stereo. Just as
2-channel stereo sound reproduction meant the
exodus of flat monaural sound, this epoch-
making new system climinates the inability to
pick
up
and
reproduce
pure
concert
hall
sound,
New 4-channel stereo uses 4 signal paths or
sound
tracks
in
the
program
material
and
in
playback approximates the complexity of the
sound
waves
which
reach
the
listener's
ear
when
attending
a
live
concert
hall
performance,
For
playback,
4
speakers
are
positioned
to
surround
the
listener.
The
sound
from
the
front
and
rear
speakers
give
the
listener
an
exciting
“sense
of presence”,
With
the
4 speakers
each
delivering
separate
sound,
left
&
right
in
front
and
left
& right
in back
of you,
you
are
literally
surrounded
with
a
wall
of
sound
which
fills
the
“hole
in
the
middle”.
This4-dimensional
musical
reproduction
makes
conventional
2-channel
stereo
seem
empty
and
insufficient.
