INTRODUCTION
The fact that you've invested in a component high fidelity system indicates you to
have a more than average interest in music. The fact that your investment includes
a Harman/Kardon receiver shows us your appreciation of uncompromised
reproduction of the music you enjoy. Throughout the design and manufacture of
this receiver, we have made every effort to assure it will meet all of your expectations.
We are confident the 430 will do this if it is properly connected and its controls and
features are clearly understood.
This manual will serve as a guide to the connection ofthe 430 and the expert use
of all its controls. We understand your desire to have the 430 operating in the shortest
possible time, so this manual has been organized to make the installation procedure
rapid, simple, and accurate. We feel a comprehensive understanding of the various
controls and features the 430 offers can best be obtained when you can hear their
effects as we describe them, so this manual is organized to allow that.
Read each section of this manual completely before you begin to make the
connections or control adjustments that section describes. You will make the right
connections or adjustments the first time you attemptthem and thus shorten the
process of installation.
WARNING: TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.

CONNECTING THE 430
On the rear panel of the 430 you will
find numerous receptacles, all clearly
and specifically marked with identifying
legends. Each of these will be dealt with
in turn. For the moment, leave the power
cord of the 430 unconnected. Place the
430 on a shelf or table, or on the floor
near where it will finally be placed when
you've completed the connections. You
should leave enough working space
around it so you can make your
connections easily and comfortably.
Although the 430 is a solid state
device, its powerful amplifiers and even
the dial scale illumination lamps will
generate heat. The 430 is designed to
operate efficiently over a wide range of
ambient temperatures, but the heat it
generates must be allowed to escape to
prevent internal temperatures from rising
too high. Adequate ventilation must be
provided. If the 430 will operate on an
open shelf, no special precautions need
be taken. If a shelf will exist above the
430, allow at least 1" to 2" of free space
above the receiver. If the 430 wi II operate
in a 3 or 5-sided (bottom, back, top and
sides) closed space, at least 2" to 4" of
free space should be allowed above it
and to either side. In custom-mounted
cabinet installations, adequate air flow
can be obtained by drilling a large cutout,
or several small holes, in the surrounding
cabinetry, both above and below the
receiver (not in the 430 housing!!!).
Open back custom installations require
no special attention. Finally, free airflow
through the bottom of the receiver must
be allowed. Never operate the 430 on a
rug or cushion that could prevent air
from entering the bottom of the
receiver.
SPEAKER SYSTEMS
Preparing for Connections:
Choosing the right wire for connecting
your speakers to the receiver will assure
the best performance. We recommend
use of 18 gauge, stranded, two-conductor
wire. This type of wire is often called
lamp, or "zip", cord and is available at
most high fidelity stores or any electrical
supply store. 18 gauge wire is thick
enough to allow lengths of up to 50 feet
to be used without affecting the low
frequency performance of your system.
For longer runs, we suggest thicker 16
gauge wire. If the length of wire you need
is relatively short, you may use thinner
20 gauge wire for your installation,
although 18 gauge wire is preferred.
Lamp cord usually provides a "code"
which is a means of identifying the con-
ductors. On some brands the insulation
surrounding one of the conductors has a
rib, sharp corner (see "a"), or indenta-
tions molded along its length (see "b");
on others a thin, colored thread is molded
inside the insulatoralong with one
conductor (see "c"). In still other brands,
the two conductors are different colors
(see "d"). Such wire will be very useful in
"phasing" your speaker systems.
Cut two lengths of wire of approxi-
mately equal size. Both should be long
enough to comfortably reach the speaker
that will be at the greatest distance from
the 430. Separate the conductors at each
end of the wire segments a distance of
about 2-3", then carefully remove about
one-half inch of insulation from each free
end. Twist the strands of each conductor
so they are smooth and tight without any
loose strands.

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 speakerwill 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.

TURNTABLES OR
AUTOMATIC CHANGERS
All record playing units provide two or
three cables (aside from the power cord)
for connection to the 430. These are the
left and right channel signal cables and
the ground connection (some turntables
combine the ground connection with one
of the signal cables). The two signal
cables are usually identified as "left
channel" and "right channel" by the use
of a color code or tabs, or the channel
identifications are molded into the insula-
tors around the pin-type 'RCA connectors.
Determine which of the cables is left and
which right and insert them into the two
corresponding receptacles on the rear
panel of the 430 marked PHONO. Press
them in as far as they will go so they are
seated snugly.
If a separate ground wire is provided,
connect its lug or stripped end underthe
knurled nut marked GND on the rear
panel of the 430. The phonograph signal
connections are now complete.
Note: The 430 is designed to operate
with a high quality MAGNETIC cartridge.
If you purchased your 430 and turntable
separately, be sure the turntable is
equipped with a cartridge of this type.
Insert the AC power cord of your
turntable into the AC receptacle
marked UNSWITCHED on the rear of
the 430. This receptacle is "live" so
long as the 430 itself is connected to a
live AC outlet, regardless of whether
the 430 is itself operating. Your turn-
table or automatic changer should be
connected to this receptacle.
FM ANTENNA CONNECTIONS
A "T"-shaped, folded dipole an-
tenna is provided with the 430 for FM
reception. However, FM performance
of the 430 will be greatly enhanced if
it is connected to an outdoor antenna
system. Many apartment buildings in
urban areas provide a master antenna
system for television reception which
can often be used successfully for FM
purposes. In some suburban and rural
areas, cable television systems exist
that can also be used successfully for
FM reception. In fact, television
antennas on private houses are often
good for FM reception.
Two types of wire, 300 ohm and 75
ohm, are used as lead-in for outdoor
antenna systems. Both types can be
connected to the 430. Find the three-
connector terminal strip on the rear
panel of the 430 marked ANTENNA.
If your lead-in is 300 ohm, it will be a
very flat wire with a conductor at each
edge. Carefully cut about 1½
11
of the
insulation material from the center of the
lead-in without damaging either con-
ductor. Strip off about ¾
11
of insulation
from each conductor and connect one of
them to each of the terminals on the
three-connector ANTENNA strip under
the bracket labeled 30011. (The term
"ohm" and the symbol "11" have
equivalent meaning.)
If your lead-in is 75 ohm, you must
use a matching transformer. The lead-in
wire will be a single round wire with a ter-
mination consisting of a metal connector
with ashort length of bare, solid, copper-
colored wire protruding from its center.
This connector is intended to be joined to
a 75n to 30011 matching transformer.
These transformers are inexpensive and
available at many television or electronic
parts supply stores. Once they are joined
to the lead-in they provide two 300 ohm
conductors that are connected to the 430
as described above. If your 75n lead-in
has a bare end, the appropriate con-
nector must be attached to it so that you
can use a matching transformer.
Where there is only one lead-in and it
must supply signal for both a television
receiver and the 430, a "signal splitter"
or "2-set coupler" can be used. Consult
your high fidelity or television dealer for
information on such devices.
If no outdoor antenna is available to
you, connect the lugs of the dipole
antenna to the 30011 terminals.
The dipole antenna will perform best
if its arms are carefully extended in a
straight line horizontally, and the entire
antenna fixed to a wall or tacked to the
back of a shelf. Dipoles are most
sensitive on the axis perpendicular to
the plane of the two arms so antenna
position is important for optimum
reception.
AM ANTENNA CONNECTIONS
A ferrite loopstick AM antenna is pro-
vided on the rear of the 430 which will
yield good reception in manyareas. It can
be oriented to improve reception of dis-
tant stations. The third terminal of the
ANTENNA strip is a connection for a
"long wire" AM antenna. AM reception
over extremely long distances can be
obtained with a well-designed long wire
antenna. Many high fidelity dealers,
especially those who have experience
with amateur and shortwave radio, can
help you with a long wire AM antenna
system.
WARNING: DO NOT MISTAKE THE
FERRITE LOOPSTICK AM ANTENNA
FOR A HANDLE. ITS BRACKET CAN-
NOT SUPPORT THE WEIGHT OF THE
430. THE 430 SHOULD NEVER BE
LIFTED, PULLED, OR PUSHED BY
GRIPPING THE AM ANTENNA.

CONNECTING TAPE
EQUIPMENT
The 430 provides facilities for both the
recording and playback of tape programs
to and from open-reel, cassette, or eight-
track cartridge equipment. Using the
signal cables provided with your tape
deck or recorder, recordings can be
made by connecting the left and right
channel TAPE 1 receptacles (under the
bracket labeled OUTPUTS) on the rear
panel of the 430 to the corresponding
input receptacles of your tape equipment.
The 430 provides outputs for two
tape recorders.
If your open-reel or cassette equipment
offers true off-tape monitoring facilities,
the left and right channel output recep-
tacles of your tape equipment should be
connected to the corresponding TAPE
MONITOR receptacles under the bracket
labeled INPUTS. Most cassette recorders
and many open-reel units do not offer
true tape monitor capability. However,
the outputs of these machines may still
be connected to the TAPE MONITOR
receptacles of the 430. Tape equipment
capable of playback only, can be con-
nected to either the TAPE MONITOR or
AUX receptacles of the 430. The choice
here will be affected by your desire or
need to reserve the AUX inputs of the 430
for use as explained below.
The remaining SWITCHED AC OUTLET
on the rear of the 430 may be used to
provide power for your tape deck or
recorder. This outlet is "live" onlywhen
the 430 is itself operating. If you wish, the
power switch of your tape equipment
may be left in the "on" position -power
to it would then be controlled by the
POWER SWITCH of the 430. If you use
this outlet, be sure the recorder's drive
system is disengaged before you switch
the 430 off.
OTHER EQUIPMENT
A pair of auxiliary inputs is available at
the rear of the 430 forthe connection of
any "high level" output equipment. A
special tuner for long wave, marine,
aircraft, or citizen's bands, etc. may be
connected -or you may choose to
connect a second tape recorder or the
output of the audio section of a television
receiver. Any number of choices is avail-
able. Consult your dealerfor information
as to what equipment is compatible with
the parameters of the AUX inputs of the
430. If you have not used the SWITCHED
AC OUTLET for a tape recorder, you can
use if for accessory equipment.
The connections to the rear panel of
the 430 are now complete. Insert its AC
power cord into a convenient wall outlet
and place the 430 in its final position in
your listening room.

OPERATING THE 430
POWER
Familiarize yourself with the front panel
controls. There are six knobs and nine
pushbuttons controlling all the features of
the receiver. Each of the controls per-
forms a different function, but instead of
discussing each control separately, we
will illustrate how they work together to
control the reproduction of sound through
the 430. Find the VOLUME control and
turn it down (counterclockwise). Push the
POWER switch to turn the 430 on.
Playing Records with the 430
Three basic controls are used to play
back disc recordings through the 430:
FUNCTION, VOLUME, and BALANCE.
Make the following adjustments to these
controls and the SPEAKERS switch after
activating your turntable or record
changer:
[1] SPEAKERS 1
[2] FUNCTION
[3] BALANCE
[4] VOLUME
- On (Push "in")
- "Phono" position
-Neutral position
(12 o'clock)
-Advance
(clockwise) to
,comfortable
loudness level.
You should now hear sound from the
disc through your system. To increase or
decrease the loudness of the playback,
the VOLUME control may be advanced
(clockwise) or turned down (counter-
clockwise). The BALANCE control if
turned counterclockwise will shift the
loudness to the left speaker by attenu-
ating (reducing the loudness of) the right
speaker. When turned in the other
direction, it has the opposite effect. The
SPEAKER 1 pushbutton connects or
defeats the loudspeakers connected to
SPEAKER SYSTEM 1, [If you have speak-
ers connected to SPEAKER SYSTEM 2,
they are controlled by the SPEAKERS 2
pushbutton on the front panel].
3
Now that you're listening to sound you
can check the phasing of your speakers.
While playing a stereo disc, depress the
MONO pushbutton switch and position
yourself midway between the left and
right spBaker systems, facing them. The
source of sound should now appearto
be coming from a point directly ahead of
you, centered between the two speakers.
If the sound has no clear-cut, centered
image, you did not connect the speaker
systems correctly. Push the POWER
switch off. Recheck your connections
both at the rear of the 430 and at the
terminals of both loudspeakers. If you are
using two dissimilar loudspeakers, it is
possible that their internal connections
have reverse polarity, causing them to be
out of phase. Reverse the connections
made at the speaker or the receiver (NOT
BOTH) for one channel ONLY. The
system should now be in phase. Push the
MONO switch to return it to stereo
position.
The phasing test can be done with any
program material, but disc recordings
are the recommended method. Stereo
material is suggested to make the effect
more obvious.
If you do not get sound at this point,
check the control positions given above.
Also, be sure the TAPE MONITOR switch
is in the "out" position. Leave the volume
control at the 9 o'clock position while
you are adjusting the other controls. If
you sti II get no sound, check the back
panel connections for PHONO, then
check the turntable itself. Note: When-
ever you check connections at the back
panel, always push the POWER switch
off.

If, at average listening levels, you hear
an objectionable (i.e. easily audible)
amount of hum, try disconnecting the
ground wire from the turntable to the 430.
Some turntable/cartridge combinations
actually produce less hum this way.
Another source of hum is inadequate
seating of the phono signal cables in the
receptacles of the 430. Check this
thoroughly.

RECEIVING FM BROADCASTS
Five basic controls are used to receive
FM broadcasts through the 430:
FUNCTION, VOLUME, BALANCE,
TUNING, and FM MUTING. Make the
following adjustments to these controls
after activating the SPEAKERS 1 switch:
[1] FUNCTION - FM Stereo
[2] BALANCE -Neutral
[3] FM MUTING -Out
[4] TUNING -Use this control to
move the dial
pointer to the
extreme end of the
dial scale.
[5] VOLUME - Advance until hiss
is audible
You should now hear a mild hissing or
rushing sound -this is atmospheric
noise picked up by the tuner section.
Depress the FM MUTING button and the
noise disappears -it has been muted.
Turn the TUNING knob in either direction
until a broadcast signal is received.
The signal strength tuning meter should
have deflected and should now be
registering the relative strength of the
FM signal you are receiving. If the
broadcast is in stereo, the red STEREO
beacon is lit -the beacon does not
illuminate when an FM station is broad-
casting monophonically. If you have
a stereo station tuned, turn the FUNC-
TION switch to FM. The 430 is now
receiving the stereo broadcast mon-
ophonically. This feature is useful for
weak stereo stations where reception is
accompanied by a large amount of noise.
The program can be received mono-
phonically without the noise. Very weak
monophonic stations may be received if
FM MUTING is defeated, but tuning from
station to station is no longer noise-free.
i
3 2
Muting Adjustment
There is a control on the rear panel
labeled MUTING ADJ. It controls the
signal threshold at which muting action
takes place when the FM MUTING
button is activated. The control has been
set at our factory to accommodate the
majority of FM reception conditions.
If you wish to readjust this control,
depress the FM MUTING button and tune
away from any station. Turn the
MUTING ADJ control until the interstation
noise (hiss) disappears.
The dial scale of the 430 is calibrated
for FM broadcast station frequencies
from 88 to 108 mHz. Each FM station in
your area has an assigned frequency that
falls within these limits. You can use
the illuminated dial pointer and scale of
the 430 to find any station in your
area if you know the assigned frequency.
Similarly, AM stations in your area have
assigned frequencies ranging from
about 550 kHz to 1600 kHz. These, too,
can be found with the illuminated
pointer and dial scale. For convenience,
a third logging scale with arbitrary
values from 0-100 is provided so you can
simplify the task of memorizing the
various assigned frequency values of
the FM and AM stations in your area.
With the logging scale, all you need
remember is that if your favorite FM
station is at 80 on the logging scale,
select FM, tune to 80, and listen.
These two examples give you a
working familiarity with the primary
controls of the 430.

OTHER CONTROLS
By far the most frequently used
controls are the FUNCTION, VOLUME,
and POWER controls, but each of the
controls we haven't yet mentioned has a
specific purpose and value. Listen
to their effect as we describe them.
TREBLE Raises (clockwise) or lowers
(counterclockwise) high frequency
content in program material on both
channels simultaneously. Neutral
position is 12 o'clock.
BASS Same effect as TREBLE control,
except works on low frequencies.
CONTOUR Works in conjunction with
VOLUME control to increase bass
energy at low volume settings.
Progressively less effect as volume level
is increased. The CONTOUR control
has no effect at VOLUME control settings
beyond 12 o'clock.
TAPE MONITOR Admits program from
any "high level" source (usually tape
recorder) connected to TAPE MONI-
TOR receptacles. It does not affect signal
appearing at the TAPE OUTPUT
receptacles. Thus, the use of the TAPE
MONITOR switch does not disturb
the recording process of whatever
source the FUNCTION switch is set to.
(Note: If the rear panel TAPE MONITOR
inputs are unoccupied and the TAPE
MONITOR switch is depressed, no
sound will be heard regardless of the
position of the FUNCTION switch.
The same will be true if the equipment
connected to the TAPE MONITOR inputs
is off). TAPE MONITOR also allows for
connection of signal processing devices.
MONO Changes any program from
st8reophonic to monophonic format.
Also processes any source connected to
a single input receptacle (such as
television sound) through both channels.
HI CUT A filter to reduce high frequency
content of any program material. Tape
hiss, record scratches and other
problems found in program material
can be effectively reduced with this
control.
LO CUT A filter to reduce low frequency
content of any program material.
Rumble from your turntable (if present)
or other low frequency problems
can be effectively reduced with this
control.
PHONES Receptacle for headphones
for private listening. Does not auto-
matically defeat speaker systems.
Headphones can be used whether your
speakers are "on" or "off".
FUNCTION Selects program for play-
back through system. Same signal
appears at TAPE OUT.
FUSES
r
SPEAKER FUSE.S···•· .•. ·.7··.•••. •.•
LEFT RIGHT •• •
3A3AG 3A3AG •• •
Three fuses are provided to protect
the 430. Two of these are the speaker
fuses and are labeled as such. They
work to protect the amplifier circuitry
from external short circuits or other
conditions which would cause excessive
current to be drawn through the
amplifiers. If one of your speakers
stops reproducing sound, first check the
connections for that speaker, then
check the speaker fuse for that channel.
Replace the fuse after correcting any
short circuit conditions (wire strands
touching the wrong terminals are the
usual cause).
The remaining fuse protects the entire
receiver from excessive currents
through the AC power line. Should this
fuse blow:
THE REPLACEMENT FUSES MUST
BE OF PRECISELY THE SAME TYPE
AS THAT SPECIFIED ON THE REAR
PANEL. USING ANY OTHER FUSES
WILL NOT PROTECT THE 430:
SERIOUS DAMAGE TO ITS CIRCUITRY
MAY RESULT.
CLEANING THE DIAL GLASS
Dust or smudges can be removed
from the dial glass with a diluted liquid
glass cleaner and a soft cloth or damp
paper towel. DO NOT use a strong
solvent-type cleaner or ammonia as
these may remove the lettering on the
face panel or cloud the dial glass.
