Installation - Pioneer SX-727 Operation Instruction Manual

INSTALLATION
Do not install the SX-I27 rn the following
places:
.
In
direct sunlight or
near
heating units.
.
In
damp,
dusty
places
or where air circulation
is
poor.
'
o
In vibration-prone,
unstable
places.
o
Do not put inflammables on the upper
surface
of the unit
nor
cover a ventilator
with its
function-preventives.
Prepare
a shelf or
a stand durable enough
for
the
large-size,
weighty SX-?27 to
be
installed.
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 ceil-
ing
and
the
amount and
arrangement
or
furniture.
Too
"'harsh"
or "bright"
a sound usually results from too
many
hard reflecting surfaces, and/or too low
a
ceiling. This condi-
tion is improved by having
ample carpeted 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
re-
ducing the distance between them.
SPEAKER CONNECTION
AND
ITUSTALLATION
CONN
ECTION
o
As shown
in
Fig. 5, connect the lead wires of
the
system
to
the
supplied speaker plugs. Be sure to
the correct polarity
and
to
cause
no short
between
(-).
o
For
the
Connect
and the
o For
the
speaker
pair.
NOTE:
When using two
pairs
of
speakers
simultaneously (with
the SPEAKER
switch set
to A +
B or
A + C),
make sure that the impedance of
each
unit
is
at
least BSl.
INSTALLATION
Optimal stereo effect is obtained when the listener is at
the
vertex
of
a
regular triangle whose
base
is the line connecting
the
left
and
right
speakers
(approx.
3ft.
to
8ft.
apart).
Wherever possible,
install the
speakers
at the
same
height;
if
the
difference
in
height
is
too
great,
the
stereo effect
deteriorates.
