Description and Features
Harman Kardon’s HK 3470 is the world’s first
stereo receiver to offer VMAx
. VMAx is a pro-
prietary signal-processing technique that cre-
ates 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 capabilities that provide for the utmost
flexibility. A high-quality phono input is avail-
able 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
state-of-the-art features and time-honored cir-
cuit designs, the HK 3470 is one of the finest
receivers ever offered by Harman Kardon.

Important Safety Information
Verify Line Voltage Before Use
Your HK 3470 has been designed for use with
120-volt AC current. Connection to a line volt-
age other than that for which it is intended can
create a safety and fire hazard, and may dam-
age 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 sell-
ing dealer before plugging the unit into a wall
Do Not Use Extension Cords
To avoid safety hazards, use only the power
cord attached to your unit. We do not recom-
mend 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.
CAUTION: To prevent electric shock,
 do not use this (polarized) 
plug with an extension cord, 
receptacle or other outlet 
unless the blades can 
be fully inserted to 
prevent blade exposure.
The lightning flash with arrowhead symbol, 
within an equilateral triangle, is intended to 
alert the user to the presence of uninsulated 
“dangerous voltage” within the product’s 
enclosure that may be of sufficient magnitude to constitute a 
risk of electric shock to persons.
The exclamation point within an equilateral 
triangle is intended to alert the user to the 
presence of important operating and 
maintenance (servicing) instructions in the 
literature accompanying the appliance.
Safety Information
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, dis-
connect it from the AC power source immedi-
ately and consult an authorized service station.
CATV or Antenna Grounding
If an outside antenna or cable system is con-
nected to this product, be certain that it is
grounded so as to provide some protection
against voltage surges and static charges.
Section 810 of the National Electrical Code,
ANSI/NFPA No. 70-1984, provides information
with respect to proper grounding of the mast
and supporting structure, grounding of the
lead-in wire to an antenna discharge unit, size
of grounding conductors, location of antenna
discharge unit, connection to grounding elec-
trodes and requirements of the grounding elec-
reminder is provided to call the CATV (Cable TV)
system installer’s attention to article 820-40 of
the NEC that provides guidelines for proper
grounding and, in particular, specifies that the
cable ground shall be connected to the ground-
ing system of the building, as close to the point
of cable entry as possible.
Installation Location
■ To ensure 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 ventila-
tion. If this product will be installed in a cab-
inet or other enclosed area, make certain
that there is sufficient air movement within

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 immedi-
ately 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

the unit from the AC outlet.
Important Information for the User
NOTE: This equipment has been tested and
found to comply with the limits for a Class-B
digital device, pursuant to Part 15 of the FCC
Rules. The limits are designed to provide rea-
sonable protection against harmful interference
in a residential installation. This equipment gen-
erates, uses and can radiate radio-frequency
energy and, if not installed and used in accor-
dance with the instructions, may cause harmful
interference to radio communication. However,
there is no guarantee that harmful interference
will not occur in a particular installation.
If this equipment does cause harmful interfer-
ence to radio or television reception, which can
be determined by turning the equipment off
and on, the user is encouraged to try to correct
the interference by one or more of the
following measures:
■ Reorient or relocate the receiving antenna.
■ Increase the separation between the equip-
ment and receiver.
■ Connect the equipment into an outlet on a
circuit different from that to which the
receiver is connected.
■ Consult the dealer or an experienced
radio/TV technician for help.
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following two
conditions: (1) this device may not cause harm-
ful interference and (2) this device must accept
interference received, including interference that
may cause undesired operation.
NOTE: Changes or modifications may cause this
unit to fail to comply with Part 15 of the FCC
Rules and may void the user’s authority to
operate the equipment.
The carton and shipping materials used to pro-
tect 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 care-
fully slitting the tape seams on the bottom and
collapsing the carton down to a more two-
dimensional 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 mate-
rials, please note that the carton and other sec-
tions of the shipping protection are recyclable.
Please respect the environment and discard
those materials at a local recycling center.
