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
