IE
Speaker
placement
In
general,
it
is
advisable
to
place
the
speakers
on
a
hard
wall
surface.
Soft
surfaces
can
often
ruin
the
deep
tones
of
the
bass,
Also
avoid
placing
the
speakers
facing
a
solid
surface
because
an
echo
effect
may
result
and
distort
the
quality
of
the
reproduced
sound.
In
summary,
place
the
speakers
on
a
very
hard
surface,
and,
if
a
hard
surface
such
as
a
window
or
panels
faces
the
speakers,
cover
it
with
soft
material
such
as
curtains.
HH
Polarity
(@®
and@)
check
After
the
connections
of
the
speaker
systems
have
been
completed,
confirm
that
the
polarity
of
the
speaker
con-
nections
to
the
speaker
terminals
is
correct.
How
to
check
Press
the
mode
pushbutton
to
the
“MONO”
position.
If
the
polarity
is
correct,
the
sound
will
seem
to
be
heard
from
the
center,
between
the
left
and
right
speakers.
If
it
is
incorrect,
the
sounds
will
not
appear
to
gather
at
the
center,
but
will
seem
dispersed.
If
so,
confirm
that
the
connections
of
the
speakers
are
correctly
made.
In
order
to
correct
the
polarity,
if
it
is
incorrect,
reverse
the
polarity
connection
between
the
amplifier
and
either
the
right
or
the
left
speaker.
NOTE:
Be
extremely
careful
that
the
terminals
or
speaker
wires
do
not
“short”
each
other
out.
Never
use
the
minus
speaker
terminal
for
ground
connections.
To
assure
finest
reception
quality
of
FM
broadcasts,
it is
necessary
to
use
an
antenna
which
is
appropriate
to
the
reception
conditions
in
your
area.
Select
the
optimum
antenna
after
referring
to
the
information
given
below.

A
place
near
the
broadcasting
station
where
signals
are
strong

this
unit
Ig
used
in
a
place
which
is
near
the
broadcast-
ing
station
and
the
signals
are
quite
powerful
enough,
or
in
a
place
such
as
the
outskirts
of
a
city
where
inter-
ference
noise
is
relatively
slight,
the
feeder
antenna
which
is
included
with
this
unit
may
be
used
to
obtain
a
ceriain
degree
of
reception,
although,
in
order
to
obtain
the
best
reception
of
which
this unit
is
capable,
it
is
recommended
that
a
special
outside
antenna
exclusively
for
reception
of
FM
broadcasts,
consisting
of
3
to
5
elements,
should
be
installed.

ll
Feeder
antenna
The
feeder
antenna
which
is
included
with
this unit
is
provided
so
that
you
can use
it
to
receive
FM
broadcasts
temporarily
until
a
special
antenna
exclusively
for
recep-
tion
of
FM
broadcasts
can
be
installed.
As
shown
in
the
illustration,
connect
this
feeder
antenna
to
the
connection
terminals
of
this
unit
marked
“'300a
BALANG-
ED"
and,
with
both
horizontal
ends
extended
as
shown,
rotate
the
feeder
antenna
to
the
left
and
right
and
up
and
down
while
listening
to
an
FM
broadcast
in
order
to
deter-
mine
the
position
of
best
reception.
When
this
position
has
been
determined,
instali
the
feeder
antenna
so
that
it
remains
in
that
position.
Figure

Feeder

lll
A
place
far
from
the
broadcasting
station
where
signals
are
weak
and
reception
is
difficult
(such
as
near
mountains
or
similar
obstacles)
In
such
a
location
as
described
above,
an
FM’
antenna
consisting
of
5
elements
or
more
should
be
installed.
In
general,
the
more
elements
which
the
antenna
has,
the
better
will
be
its
directional
characteristics.
It
is
suggested,
therefore,
that
the
weaker
the
signal
reception
in
your
area,
the
more
elements
the
antenna
should
have
in
order
to
obtain
good
reception.

Connection
between
the
antenna
and
the
receiver
The
connection
wire
which
is
used
between
the
antenna
and
the
antenna
input
terminals
of
the
receiver
is
usually
a
300-ohm
parallel
feeder
wire
or
a
75-ohm
coaxial
cable.
In
comparison
to
feeder
wire,
a
coaxial
cable
is
more
resistant
to
external
interference,
and
also
prevents
fluctuations
of
the
signal
level
which
might
be
caused
by
environmental
weather
conditions.
In
order
to
obtain
the
finest
performance
from
this
unit,
itis
recommended
that
coaxial
cable
be
used
rather
than
feeder
wire.
Use
coaxial
cable
of
the
type
SC-2V
or
3C-2V.
Connection
to
the
FM
antenna
terminals
of
this
unit
This
unit
includes
two
pairs
of
FM
antenna
input
terminals:
one
pair
of
the
300-ohm
type
and
one
pair
of
the
76-ohm
type.
For
this
reason,
connections
can
be
made
by
using
either
a
300-ohm
parallel
feeder
wire
or
a
75-ohm
coaxial
cable.
@
If
connections
are
made
to
the
“3000
BALANCED"
terminals
Connections
can
be
made,
as
shown
in
figure
8,
by
using
300-ohm
parallel
feeder
wire.
When
this
connection
is
made,
the
wire
between
this
unit
and
the
antenna
should
be
as
short
as
possible.
