COMPOSITION OF
A
4-CHANNEL
STEREO SYSTEM
A
4-channel stereo system
with
the QX-646 can include
two or
even
three pairs
of
speaker systems,
a turntable,
a
tape deck
(reel-to-reel
or
cassette),
a
cartridge
tape
player, etc.
(see
Fig.
2).
INSTALLATION
For
safety and
reliability and
to
protect the
outward
appearance
of
each component, please
do not
install
them in any of the following
places:
.
In direct sunlight or
near
heating
units.
.
In
a
poorly ventilated, dusty,
or damp place.
.
In
an unstable place where there is significant vibration
or inclination.
Also, when playing
CD-4 records,
do not
install
near
poorly
shielded
electronic equipment or equipment emit-
ting
interference signals, (e.9. television set), since high
frequency characteristics
up
to
45kHz are required for
CD-4 records.

A
WORD ABOUT ROOM ACOUSTICS
The
quality of
reproduced
iound
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
harsh
or "bright"
a
sound usually results
from too
many hard
re-
flecting
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 "dead-
ness." Furniture may be rearranged
to
provide
irregular reflection of the
sound.
ABOUT
SPEAKER SYSTEMS
For the
best 4-channel stereo performance,
it
is
desirable
to
use
four
speaker systems
having the
same
characteristics.
if
it
is
difficult to
satisfy
this
requirement,
it
is
suggested
that
speaker systems
be selected and arranged
as
follows:
o
Select
two
speaker systems having
the
same
characteristics, and arrange them
in
the front.
o
For the
rear
channels,
select
two
speaker
sys-
tems
as
similar to the
front
speakers
as
possible.
