CONNECTIONS
SPEAKER SYSTEM CONNECTIONS (Fig.
1)
The amplifier is provided with two
sets
of
SPEAKERS
output
terminals. Use
the
A
set when connecting
only
one set
of
speakers.
Viewed from the
front, the
R
(right
channel)
SPEAKERS
terminals are
on the right
and
the
L
(left
channel)
SPEAKERS
terminals are
on the
left.
Connect
the left
channel
speaker
to the
L terminals and the
right
channel
speaker
to the
R
terminals.
The red
L
and
R
SPEAKERS terminals
have
a plus
polarity
and
the black
terminals have
a
minus
polarity and the
speaker systems
have also
the
same
dual
polarities. When
connecting,
always connect minus
to
minus and plus
to
plus.
Cautions when connecting
the
speakers
1.
The
speaker
output
terminals have
polarities:
minus
(black) and plus
(red).
The input
jacks
on the
speakers
also have
plus and minus polarities. When connecting,
make
sure
that
these
polarities
are
aligned: plus
to
plus
and
minus
to
minus.
lf the left
and right
speaker
polarities
are misaligned,
the
reproduced sound
will
not
display
a
natural
stereo
effect.
2.
Use
speakers
with a
nominal impedance ranging from
6 ohms
to
16 ohms.
3.
Never
use
the
speakers
with
the
speaker
output
terminals
shorted (minus and plus jacks
connected)
since
this
may
damage
the power transistors in the amplifier.
Processing
and connecting the
speaker cords
(Fig.2)
1.
Cut
off
the
covering
of
the
speaker
cords
as
shown
in
Fig.2-e.
2.
lf
the
strands
at the tip of
the cord
are
pointing
in
all
directions,
twist
them
with your thumb
and forefinger.
Otherwise some
of
the
strands
may
come into contact
with
other terminals
and cords, and
cause a
short.
3.
Push
the
minus (black)
button
of
the
speaker
terminals
with your
finger
and insert the minus
speaker
lead
(black)
into
the hole
above
the
button.
The
lead
is
locked
into position when the button
is
released. Check
that
the
lead
is
connected
firmly
(Fig.
z-@t'
4.
ln the
same
way, connect the
plus speaker lead (red)
to
the plus terminal
(red).
5.
Check
that the core wires
of
the speaker leads are not
projecting
from the
terminals.
lf
they
should come
into
contact, this
will
give
rise
to
a
shortcircuit.
