Introduction

Congratulations!

Harman Kardon HK 3470 you are about to
begin many years of listening enjoyment. The
HK 3470 has been custom-designed to provide
all the excitement and power of rock, jazz and
popular music, and every nuance of classical
selections.

within the HK 3470 to make all of this happen,
hookup and operation are simple. Color-keyed
connections and a comprehensive remote con-
trol make the HK 3470 easy to use.

To obtain maximum enjoyment from your new

read through this manual. This will ensure that
connections to speakers, source playback units
and other external devices are made properly.
In addition, a few minutes spent learning the
functions of the various controls will enable 
you to take advantage of all the power the
HK 3470 is able to deliver.

If you have any questions about this product, its
installation or operation, please contact your
dealer, your best local source of information.

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
outlet.

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

RISK OF ELECTRIC SHOCK

DO NOT OPEN

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.
