Stereo System - Pioneer SX-525 KW Operating Instructions Manual

A
WORD ABOUT ROOM ACOUSTICS
The quality
of
reproduced sound varies according to the
size
and
shape
of
the room, the
materials
of
walls, floor
and
ceiling and the amount and arrangement
of
furniture.
Too
"ha.rsh"or"bright"
a
sound
usually results from too many hard
reflecting
surfaces,
and/or too low
a
ceiling. This condition
is
improved
by
having ample carpet area
or
covering the wall
(especially
that
facing
the
speakers)
with
a
thick curtain.
On
the other
hand,
too many
absorbing surfaces
will
tend to
"soak
up"
the
sound, resulting
in
a
certain
"deadness."
Furniture
may be rearranged to provide irregular reflection of
the
sound.
In
any event, the true stereo effect is lost
if
the
two
speaker systems
are placed
too far
apart. This may
be
corrected
by
angling them slightly toward
each
other
or
reducing the distance between them.
4-CHANNEL
STEREO SYSTEM
conventional 2-channel stereo
systems are designed so that
instrumental and vocal music can be reproduced
in
stereo
through
left
and
right
speakers placed
in front of the
listener.
In
contrast, the newly developed 4-channel stereo system
fea-
tures a high
degree
of reproduction of full dimensional
sound
in
concert halls, including applause and the hum of
audience
voices
in
addition
to
stereo
sound from musical instruments,
through the conventional
two-speaker systems plus
two
more
speakers one
each at the rear
left
and rear
right. consequenily,
you
car] get magnificently
lifelike
quadraphonic sound far
superior to that of
2-channel stereo.
Model QL-600, Quadralizer Amplifier, combined with your
SX-525,
gives
you quadraphonic
sound.
See
Fig.
11.
HOW
TO
US,E
THE OL-600, OUADR ALIZER AMPLIFIER
To obtain quadraphonic
sound,
combine the pioneer eL-600
with your
SX-525.
The
QL-600 has
a
quadralizer circuit
for
converting
a
z-
channel stereo signal into
a
4-channel stereo signal
plus
am-
[JEE.
o
o
plifiers for
driving the two rear speaker
systems.

As
shown
in
Fig. L2,
the eL-600 can be plugged
into
the
TAPE REC and TAPE MoN jacks of your
sx-siB,
giving you
quadraphonic sound of the
MATRIX
or PHASE SHIFT
tvp..
rAPE
DEcK
with
the MATRIX
system, quadraphonic recording
ot-rvt
stereo broadcasts are reproduced
to
perfection.
what's more, with a quadraphonic
stereo tape deck (pioneer
QT-6600,
for
example) connected
to the eL-000
as
shown in
Fig. 12, discrete 4-channel
tapes can be
reproduced.
