CONNECTIONS
PRECAUTIONS
e Set the POWER
switch to ON
only when you
have completed all the connections of the stereo
system.
Always
set this switch to its bottom
position (OFF) if you want to change the con-
nections.
e All
the
receiver's
jacks
are
aligned
for easy
connection in two rows: the top row for L (left
channel) and the bottom row for R (right chan-
nel). Always connect L to L and R to R with the
audio component output and input jacks.
@ Make
sure
that
the
connections
are
secure.
Improper
connections
can generate
noise and
cause the sound to be cut off.
SPEAKER
SYSTEMS
The receiver is provided with two sets of SPEAK-
ERS
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
just
like
the
speaker
systems
themselves.
When
connecting,
always
connect
minus to minus and plus to plus (Fig. 1).

NOTE:
If you want to use two sets of speaker systems, make sure
that the impedance
of each system
is 8 ohms or more.
If the impedance
is less than
8 ohms,
the protective
circuitry will be actuated
when
the volume is turned up
and you will not be able to enjoy proper stereo perform-
ance,
Connecting the speaker lead wires to
the SPEAKERS terminals (Fig. 2)
1. Strip about
10mm
of the insulation from the
end of the speaker lead wires. If the conductor is
stranded, twist the strands together so that they
do not come into contact with other terminals.
2. Depress the terminal buttons and insert the lead
wires into the terminal holes.
8. Release
the
buttons
and
check
that the lead
wires are secure.

NOTES:
1. The
high output power
of this receiver requires that
the speaker lead wires have an ample current carrying
capacity.
Use wires with a high capacity and connect
them securely.
If you use low capacity
wires and do
not connect them properly, the reproduced sound will
be
adversely
affected
and
heat
generation
or short
circuits may be caused.
2. This receiver delivers a high output power and so make
sure that you use speakers with a high allowable input.
TURNTABLE CONNECTIONS
Connect
the output cords of a turntable using a
moving
magnet (MM) cartridge to the PHONO
1
input jacks. Connect the ground lead of the turn-
table to the GND terminal on the receiver (Fig. 3).
NOTES:
e
In addition to turntables using MM cartridges, there are
others that employ induced magnet (IM), moving iron
(MI)
and
high-output
moving
coil
(MC)
cartridges.
If you intend to use a turntable with a low-output MC
cartridge, always provide a special MC cartridge boost-
ing transformer or head amplifier.
