Ground Connections - Pioneer SX-828 Operating Instructions Manual

SPEAKER CONNECTION
AND
INSTALLATION
LEFT
CHANNEL
o
As shown
in
Fig. 4, connect the lead wires of the
speaker
system
to
the
supplied speaker plugs. Be sure
to
observe
the correct polarity
and
to
cause
no short circuit
between
@ and
Q.
.
For the
main set
of
speakers, use
the
A
speaker sockets.
Connect the right-channel
speaker
to
the
socket marked
R,
and
the left
channel speaker
to
the socket marked L.
o
For the
second
(third) pair
of
speakers,
use
the B
(C)
speaker
sockets. Connect
in
the
same
way
as
for
the first
pair.
NOTE: ln
order
to
use
two pairs
of
speakers
slmultaneously
(with
the
SPEAKER switch set
to
A+B
or
A+C), the
impedance
of
each unit
must
be
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.
Sft.
to
Sft.
apart).
Wherever possible, install
the
speakers
at
the
same height;
if
the
difference
in
height
is too great, the
stereo effect
deteriorates.
ANTENNA AND
GROUND CONNECTIONS
ffi
FM ANTENNA
FM
broadcast signals are obstructed somewhat by mountains,
buildings, and other obstacles. Therefore, even
if
a station
is
nearby,
a
high-gain antenna may be
required. Select
the
antenna
in
accordance
with
the following
rules:
o If
the
receiver is
to
be
located
in
a
wooden building
and
stations are nearby, use the T-type antenna which
comes
with
the SX-828.
As shown
in Fig.
5, connect the feeder
terminals
of
the
antenna
to
the FM
antenna terminals.
Stretch out the
antenna
proper
and secure
it
to the
ceiling
or
a wall
in
such
a
manner
that pickup is optimum,
as
determined
by
listening
to
the
station
to
be
received.
Refer to FM RECEPTION on
page
9
.
o
If
orientation
of
the T-type
antenna does
not
eliminate
background noise, connect an FM outdoor antenna
to
the
antenna terminals
as
shown
in Fig.6.
Instead
of
a special
FM
antenna,
a combination
FM/TV
antenna may
be
used.
NOTES:
o
A
varlety
of
FM
antennas are available. Consult
your
dealer.
r
ln
ocations adjacent
to
heavily
traveled
streets,
around factories or
near
high vo tage
power transmission ines,
use
of
an FM
antenna
may
not glve the
desired
noise
attenuatlon.
ln
such
cases, consult
your
dealer concering
a
coaxlal
cab
e
feeder (75f,)) for
the
FM
antenna. When using coaxial
cab
e,
make connectlons
to
the
