Place the unit on a firm and level
surface.
Avoid installing it:
@ In moist or humid places;
Close to heating equipment or in places
exposed to direct sunlight;
In adirect draft from an air conditioner
or in other very cold locations;
M@ In places subject to excessive vibration
or dust;
Hin poorly ventilated places.
Moving the Unit.
Before moving the unit, be sure to unplug
the power cord from the AC outlet and
disconnect all wires to antennas and to
other stereo components.
Do Not Open the Cabinet.
Do not attempt to service this unit.
Tampering with internal components can
cause fire or shock, and may void your
guarantee.
If water or small objects enter the unit,
unplug the power cord immediately and
consult an authorized Harman Kardon
service center. Using the unit under such
conditions may cause a fire or shock
hazard.
Cleaning.
Remove dust by wiping the unit with a soft,
dry cloth. If necessary, use a soft cloth
lightly dampened with mild soapy water;
then wipe with a dry cloth. Never use
benzine, thinner, alcohol or other volatile
agents, and avoid spraying insecticides
near the unit.

Thank you for choosing a Harman Kardon
receiver.
And congratulations. Your new unit is an
exceptionally well-engineered product that
will give you years of superb performance.
Among its special features are:
@ High Instantaneous
Current Capability
The amplifier in the HK3500 reacts rapidly
to musical transients, providing the
instantaneous current necessary to
precisely drive and control nearly any
loudspeaker system.
@ Ultrawide Bandwidth
The circuitry is designed to deliver
extended frequency response, while
keeping phase shift well outside the audible
spectrum. The result is stereo imaging and
clarity with remarkably accurate spatial
positioning of vocals and musical
instruments.
B Low Negative Feedback
Conventional designs rely heavily on
negative feedback to reduce Total
Harmonic Distortion. This results, however,
in excessive Transient Intermodulation
Distortion, audible in the harsh, grating
quality of the sound. Harman Kardon
keeps negative feedback low for smoother,
clearer reproduction of complex musical
sounds, such as those of stringed
instruments.
@ Discrete Circuitry
For maximum design flexibility and highest
possible performance, the circuitry has
been designed using discrete electronic
components, not off-the-shelf integrated
Circuits.
HARMAN KARDON HK3500 STEREO
RECEIVER
@ Sophisticated Electronic
Protection Circuitry
Harman Kardon's unique protection circuitry
guards the amplifier from short-circuited or
damaged speakers and wires, without
impairing sound quality by the use of
current limiting or output relays.
@ Automatic Tuner Switching
When not in use, the tuner circuitry is
automatically turned off, eliminating any
electronic interference and assuring optimal
performance of amplifier circuitry.

Packaging
Save all packing material. It is essential for
shipping should you move, or in the event
the unit ever needs repair.
Placement
Unit may be placed on top of or beneath
other stereo components, so long as its
placement meets the cooling requirements
of the component beneath it.
Connecting Other Components
1. Make sure receiver and other
components are turned off.
2. Connect each component's Output
jacks to the corresponding Input jacks
on the back of your receiver. Use the
white, black or gray plugs to connect
Left channel jacks; use the red plugs
for Right jacks.
NOTE:
1. When connecting a turntable, also
connect the ground wire from the
turntable to the terminal marked “GND”
next to the Phono jacks.
2. The receiver is designed for use with
turntables using moving magnet
cartridges. !f you are using a moving
coil cartridge, place a step-up
transformer between the turntable and
receiver.
3. When connecting tape decks, also
connect the “Out” jacks on the receiver
to the “Input” jacks on the tape deck. 2.
4. To connect an equalizer and/or other
external signal processing
componenis, use the receiver's Tape 1 3.
or Tape 2 jacks. Then connect your
tape deck to the Tape Monitor jacks
provided on the last outboard 4.
component. To use the signal
processing components, press the
appropriate function button (Tape 1 or
2) on the front of your receiver. To use
your cassette deck, press the Tape
Monitor buttons on the signal
processing components.
5. The Video and Aux jacks may be used
to connect VCR or TV audio lines, a
DAT recorder, or any other desired line
level source.
Connecting Antennas
Choosing an FM antenna.
Select the antenna that best meets your
needs:
1. An indoor dipole antenna is supplied
with your receiver. This will work well if
you are located in a strong signal area.
Other indoor antennas are available
which may improve reception by
offering greater positioning flexibility.
If reception is unsatisfactory using
indoor antennas, an outdoor antenna
should be installed.
Alternatively, you may connect to an FM
cable antenna, if available.

Connecting the FM antenna.
Connect the leads to the screw-down
terminals marked “FM 300QBAL” on the
back of the receiver.
If coaxial cable is used:
(a) Connect the cable center wire to
the FM screw terminal, and
connect the shield to the “GND”
terminal, as indicated by the lines
marked “75QUNBAL”.
(b) Or, connect a 75-300Q converter
to the coaxial cable. Then attach
the leads from the converter to the
terminals marked “3QOOQBAL”.
Connecting an AM Antenna.
Your receiver comes with an AM loop
antenna which provides good reception in
most locations. For best results, place this
antenna away from the unit and away from
contact with any metal object.
In areas where AM signals are weak, an
outdoor AM antenna may improve sound
quality.
Connect the AM antenna leads to the
screw-down terminals marked “AM” on the
back of the receiver.
Subwoofer Out
Connect these jacks, if desired, to a
powered subwoofer, or a power amplifier
driving a subwoofer. This output may also
be used for surround-sound equipment or
any external component requiring a line
level input.
Wired Remote Control
To control your receiver with an external
infrared remote sensor, connect the wire
from the remote sensor to the “Remote In”
jack on the back panel. Or, if you have a
stereo component with a built-in infrared
remote sensor and a “Remote Output” jack,
it may be possible to connect this jack to
the “Remote In” jack of your receiver. All
Harman Kardon products with “Remote In”
and “Remote Out” jacks are compatible with
one another, except for the Citation 22, 24
and 25. Other manufacturers’ remote
sensors may not be compatible, but it will
not hurt to experiment.
A second wire may be used to connect your
receiver's “Remote Out” jack to the
“Remote Input” of another stereo
component. Continue this process to
include additional components (if
compatible).
To control your receiver, you may use the
remote control supplied with the HK3500.
Or you may use a universal remote control
unit, such as Harman Kardon’s
Masterworks™, which can also control
other components, such as TVs, VCRs,
tape decks and CD players. Masterworks
is available from your Harman Kardon
dealer.

the remote control.
Operating Conditions
The control unit operates effectively within a
distance of 7 meters (23 feet) and an angle
of 30° from the receiver. Using the control
near fluorescent lights may shorten this
range, as will any dust or dirt that
accumulates on the front of the remote
control, or the “Remote Sensor’ area of the
receiver. Also avoid blocking the line of
sight between receiver and remote.
The control unit is powered by two AA
batteries, included with your receiver.
When you replace weak batteries, replace
both at the same time. When the remote is
to be unused for an extended period,
remove the batteries to prevent damage
from corrosion.
