Harman Kardon 430 Owner's Manual page 4

Connecting Speakers to the 430:
Find the row of four connectors on the
back panel of the 430 marked SPEAKER
SYSTEM 1. Starting with either Left or
Right pair of connectors, push firmly in
on the plastic head of each connector,
revealing an opening. Insert each of the
bare conductors at the end of one of the
lengths of wire you've prepared into the
opening. Release the connector. Each of
the two conductors should be locked
firmly in place in its own connector. Take
the other end of this wire and connect the
bare conductors to the two terminals on
one of your speakers. Now (this is
important) note to which connector (red
or black) on the 430, and to which
speaker terminal, the coded side of the
wire is connected. Connect the other
speaker to the other two connectors
under SPEAKER SYSTEM 1, being sure
the coded side of this wire is connected
to both the 430 and the speaker in the
same way as the first wire. The left
channel connection should be made to
the speaker placed at the left side of your
listening area. The right channel connec-
tion should be made to the speaker
placed at the right side of your listening
area. Be certain [this is very important]
all these connections are tight and that
all the strands of tne wires are firmly
seated in the connectors of the 430 and
under the terminals of your speaker
systems. Any loose strands of wire could
touch other terminals and cause short
circuits, which might cause the speaker
fuse to blow.
If you have been careful to follow these
directions, your speakers will be properly
"phased." We will describe how to check
this by ear when the other connections
are completed and your system is
operating.
Note: Two equal lengths of wire are
suggested, even if one speaker will be
quite close to the 430, to prevent any
imbalance in the system. Later, when you
put the components in your system into
their final positions, you can neatly coil
any excess wire and place it
inconspicuously.
If, now or later, you wish to connect a
second pair of speakers, you may use
the SPEAKER SYSTEM 2 connectors of
the 430 following the procedure outlined
above. You may do this only if each
speaker has a rated impedance
of
8
ohms or higher.* If either pair of
speakers have rated impedances of
4 ohms, you should not connect them
without special advice from your high
fidelity dealer. SERIOUS DAMAGE TO
THE 430 CAN RESULT FROM SUCH
USE.
*Note: All stereophonic solid state am-
plifiers can normally accommodate only
one pair of 4 ohm speakers. This means
that if you have connected a pair of 4 ohm
speakers to SPEAKER SYSTEM 1, no
additional speakers of any kind may be
connected to either SPEAKER SYSTEM 1
or SPEAKER SYSTEM 2 without consult-
ing with your dealer, Harman/Kardon, or
the manufacturer of your speakers.
