Description and Features
Harman Kardon’s HK 3470 is the world’s first
stereo receiver to offer VMAx
etary signal-processing technique that creates
an open, spacious sound field when only two
loudspeakers are available. VMAx circuitry is able
to decode the ambience of a concert hall or theater from a stereo recording.
The HK 3470 is a full-featured Stereo receiver,
with five inputs and an FM stereo/
FM/AM tuner with RDS capabilities that provide
for the utmost flexibility.A high-quality phono
input is available so that you may continue to
enjoy your existing record collection as well as
the latest CD recordings.
The HK 3470’s powerful amplifier uses
traditional Harman Kardon High-Current Design
philosophies to meet the wide dynamic range of
any program selection.
Harman Kardon invented the high-fidelity receiver more than forty-seven years ago.With stateof-the-art features and time-honored circuit
designs, the HK 3470 is one of the finest
receivers ever offered by Harman Kardon.

INTRODUCTION 3
Important Information
Important Safety Information
Verify Line Voltage Before Use
Your HK 3470 has been designed for use with
220-240-volt AC current.Connection to a line
voltage other than that for which it is intended
can create a safety and fire hazard, and may
damage the unit.
If you have any questions about the voltage
requirements for your specific model, or about the
line voltage in your area, contact your selling
dealer before plugging the unit into a wall outlet.
Do Not Use Extension Cords
To avoid safety hazards,use only the power cord
attached to your unit. We do not recommend
that extension cords be used with this product.
As with all electrical devices, do not run power
cords under rugs or carpets or place heavy
objects on them. Damaged power cords should
be replaced immediately with cords meeting factory specifications.
Handle the AC Power Cord Gently
When disconnecting the power cord from an AC
outlet, always pull the plug, never pull the cord.
If you do not intend to use the unit for any considerable length of time, disconnect the plug
from the AC outlet.
Do Not Open the Cabinet
There are no user-serviceable components inside
this product. Opening the cabinet may present a
shock hazard, and any modification to the product will void your guarantee. If water or any
metal object such as a paper clip, wire or staple
accidentally falls inside the unit, disconnect it
from the AC power source immediately, and consult an authorized service station.
Installation Location
■ To assure proper operation, and to avoid the
potential for safety hazards, place the unit on
a firm and level surface.When placing the
unit on a shelf,be certain that the shelf and
any mounting hardware can support the
weight of the product.
■ Make certain that proper space is provided
both above and below the unit for ventilation.
If this product will be installed in a cabinet or
other enclosed area, make certain that there
is sufficient air movement within the cabinet.
Under some circumstances a fan may be
required.
■ Do not place the unit directly on a carpeted
surface.
■ Avoid installation in extremely hot or cold
locations, or an area that is exposed to direct
sunlight or heating equipment.
■ Avoid moist or humid locations.
■ Do not obstruct the ventilation slots on the
top of the unit, or place objects directly over
them.
Cleaning
When the unit gets dirty, wipe it with a clean,
soft, dry cloth. If necessary, wipe it with a soft
cloth dampened with mild soapy water, then a
fresh cloth with clean water.Wipe dry immediately with a dry cloth. NEVER use benzene,
aerosol cleaners, thinner, alcohol or any other
volatile cleaning agent. Do not use abrasive
cleaners, as they may damage the finish of metal
parts.Avoid spraying insecticide near the unit.
Moving the Unit
Before moving the unit, be certain to disconnect
any interconnection cords with other components, and make certain that you disconnect the
unit from the AC outlet.
Unpacking
The carton and shipping materials used to protect your new receiver during shipment were
specially designed to cushion it from shock and
vibration.We suggest that you save the carton
and packing materials for use in shipping if you
move, or should the unit ever need repair.
To minimize the size of the carton in storage,
you may wish to flatten it. This is done by carefully slitting the tape seams on the bottom and
collapsing the carton down to a more twodimensional appearance. Other cardboard
inserts may be stored in the same manner. Packing materials that cannot be collapsed should be
saved along with the carton in a plastic bag.
If you do not wish to save the packaging materials, please note that the carton and other sections of the shipping protection are recyclable.
Please respect the environment and discard
those materials at a local recycling center.

However, occasionally the actual impedance will
vary,depending upon the program material.
When the impedance drops too low, the HK

occur frequently, be sure to select only one set of
speakers at a time until you are able to obtain
speakers with a higher nominal impedance.
