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.

Installation and Connections

Audio and Speaker Connections

After unpacking the unit and placing it on a
solid surface capable of supporting its weight,
you will need to make the connections to your
audio and video equipment. These steps need to
be done only when the receiver is first installed
or when a change is made to the input source
equipment.

Audio Equipment Connections

We recommend that you use high-quality inter­connect cables when making connections to
source equipment and recorders to preserve the
quality of the signals.

When making connections to audio source
equipment or speakers it is always a good prac­tice to unplug the unit from the AC wall outlet.
This prevents any possibility of accidentally send­ing audio or transient signals to the speakers
that may damage them.

1. Connect the analog output of a CD player to
the CD inputs

NOTE:When the CD player has both fixed and
variable audio outputs, it is best to use the fixed
output unless you find that the input to the
receiver is so low that the sound is noisy, or so
high that the signal is distorted.

2. Connect the Play/Out jacks of a cassette deck,
CDR, MD or other audio recorder to the Tape
Monitor Play jacks
jacks on the recorder to the Tape Monitor
Rec. Out jacks
tape deck connected to these jacks is a three­head unit or has off-head playback, it will be
possible to monitor the output of the source
being recorded.

3. Connect the output of a second audio
recorder, CDR, MD or other line-level audio
device to the Tape 2 Play jacks
recorder is used, connect its Rec/In jacks to the
matching Tape 2 Record outputs

4. The audio output of any electronics product
with a line-level output, such as a TV set, satel­lite receiver or DVD, may be connected to the
Aux jacks

5. Connect the outputs of a turntable with a
moving magnet cartridge to the Phono inputs



.

7. Connect an FM antenna to the FM Antenna
connection



. The FM antenna may be an
external roof antenna, an inside powered or wire
lead antenna or a connection from a cable sys­tem. Note that if the antenna or connection uses
300-ohm twin-lead cable, you must use the
300-ohm-to-75-ohm adapter supplied with the
unit to make the connection.

Speaker Connections

To ensure that all the audio signals are carried
to your speakers without loss of clarity or resolu­tion, we suggest that you use high-quality
speaker cable.Many brands of cable are avail­able, and the choice of cable may be influenced
by the distance between your speakers and the
receiver, the type of speakers you use, personal
preferences and other factors.Your dealer or
installer is a valuable resource for help in select­ing the proper cable.

Regardless of the brand of cable selected, we
recommend that you use a cable constructed of
fine, multistrand copper with an area of min.

2

2 mm

.

Cable with 1.5 mm
of less than 3 meters.We do not recommend
that you use cables with an area of 0.8 mm

2

may be used for short runs

2

or
smaller due to the power loss and degradation
in performance that will occur.

Cables that are run inside walls should have the
appropriate markings to indicate listing with the
appropriate testing agency standards. Questions
about running cables inside walls should be
referred to an installer or a licensed electrical
contractor who is familiar with applicable local
building codes in your area.

When connecting wires to the speakers,be
certain to observe proper polarity. Remember to
connect the “negative” or “black” wire to the
same terminal on the receiver and the speaker.
Similarly, the “positive” or “red” wire should be
connected to the like terminals on the HK 3470
and speaker.

We also recommend that the length of cable
used to connect speaker pairs be identical. For
example, use the same length piece of cable to
connect the Speaker 1 left and right or
Speaker 2 left and right speakers, even if the
speakers are a different distance from the
HK 3470.

NOTE: While most speaker manufacturers
adhere to an industry convention of using black
terminals for negative and red ones for positive,
some manufacturers may vary from this configu­ration.To assure proper phase, and optimal per­formance, consult the identification plate on
your speaker, or the speaker’s manual to verify
polarity. If you do not know the polarity of your
speaker, ask your dealer for advice before pro­ceeding, or consult the speaker’s manufacturer.

Connect the speakers using the following steps:

1.

Connect the main speakers to the Speaker 1

terminals .

2.

Connect a second set of speakers,or speakers

that are in a second room location, to the
Speaker 2 terminals



.

3. When an optional, powered subwoofer is
used, connect the outputs of the left and right
Subwoofer Out jacks



to the line-level
inputs of the subwoofer. When the subwoofer’s
amplifier has stereo inputs, run interconnects
from both jacks.When the subwoofer has a
mono input only, use the bottom output jack for
the connection. When a separate passive sub­woofer is used, these connections will be made
to the optional amplifier that powers the sub­woofer. If the (passive) subwoofer or Sub/Sat
system has only speaker-level inputs and out­puts, connect the

Speaker 1

terminals to the
speaker-level inputs on the subwoofer, and then
connect the speaker-level outputs on the sub­woofer to your main left and right speakers,
following the instructions provided with the
subwoofer.

System and Power Connections

The HK 3470 is designed for flexible use with
external control components and power ampli­fiers.These connections are easy to make during
an initial installation, or at a later date should
you choose to upgrade your system.

Remote Control Extension

If the receiver is placed behind a solid or smoked
glass cabinet door, the obstruction may prevent
the remote sensor from receiving commands. In
this event, an optional remote sensor may be
used. Connect the output of the remote sensor
to the Remote IR In jack

If other components are also prevented from
receiving remote commands, only one sensor is
needed. They may use this unit’s sensor or a
remote eye by running a connection from the
Remote IR Out jack
on Harman Kardon or other compatible equip­ment.

External Audio Power Amplifier
Connections

If desired, an optional, external amplifier may be
used in place of the HK 3470’s internal power
amplifier.

To connect an external power amplifier, first
remove the Pre-Out/Main-In Jumper Pins
that connect the Preamp Outand Main In



jacks on the rear panel. Keep the jumpers in
a safe place should they be needed at a later
time.

Using high-quality audio interconnect cables,
connect the Preamp Out jacks
jacks on your power amplifier. Make certain to
match the right output to the right input and the
left output to the left input.

Note that when an external power amplifier is
used, no special adjustments are required.All
volume and other control adjustments are made
using the standard front panel or remote con­trols.

AC Power Connections

This unit is equipped with an accessory AC out­let. It may be used to power accessory devices,
but it should not be used with high-current draw
equipment such as power amplifiers.The total
power draw may not exceed 100W at this out­let.

This Switched AC Outlet



will receive
power only when the unit is on. This is recom­mended for devices that have no power switch,
or those with a mechanical power switch that
may be left in the “ON” position.

NOTE: Devices with electronic power switches
may only go into a Standby mode when plugged
in here.

Power to this outlet is removed when the unit is
in the Standby mode, or when the Main Power

Switch

1

is in the “OFF” position.

Speaker Placement

For optimal listening enjoyment, and for sound­field reproduction that best re-creates the origi­nal recording, it is good practice to place the
speakers so that they form a triangle with the
speakers at the front of the room, and the pre­ferred listening spot at the third point of the tri­angle.The distance between each speaker and
the listener should be identical.

For example,if the speakers are 2,5 meters from
one another, each of the speakers should opti­mally be placed so that they are also 2,5 meters
from the listener. It is also desirable to place
speakers so that their tweeters,or highfrequency
drivers, are aimed at ear height when you are
seated in the listening position.

A good starting point for speaker placement is to make the
distance between the two speakers and the distance between
either speaker and the listener identical.

To optimize the sound field, or to suit your lis­tening room environment, you may find that
some experimentation is required to find the
correct location. Ideally, pans from left to right
across the front of the room should sound
smooth, and instruments should appear to be
coming from the proper location within an
orchestra.

The placement of subwoofers should be done as
suggested in the manufacturer’s instructions. In
general, subwoofers often produce best results
when they are placed in the corner of a room,
along the same wall as the speakers, but optimal
placement will vary widely depending on room
size, the subwoofer type and the placement of
rugs and furniture in a room. It may be helpful
to temporarily position the subwoofer in the
usual listening position, then walk around the
room while program material is playing until the
bass reproduction sounds best to your ears.That
location is likely to be the optimum position for
the subwoofer.

Finally, when all connections are complete, plug
the power cord into a nonswitched 230-volt AC
wall outlet.You’re ready to enjoy the HK 3470!

RDS Operation

The HK 3470 RDS is equipped with RDS (Radio
Data System), which brings a wide range of infor­mation to FM radio. Now in use in many coun­tries, RDS is a system for transmitting station call
signs or network information, a description of
station program type, text messages about the
station or specifics of a musical selection and the
correct time.

As more FM stations become equipped with RDS
capabilities, the HK3470 RDS will serve as an
easy-to-use center for both information and
entertainment. This section will help you take
maximum advantage of the RDS system.

RDS Tuning

When an FM station is tuned in and it contains
RDS data, the HK 3470 RDS will automatically
display the station’s call sign and the RDS indi­cator

P

will light in the Information Display as

well as indicators for the RDS services program
type PTY

station. As soon as a radiotext message is
received completely the radiotext indicator RT
will turn on too.

RDS Display Options

The RDS system is capable of transmitting a wide
variety of information in addition to the initial
station call sign that appears when a station is
first tuned. In normal RDS operation the display
will indicate the station name, broadcast network
or call letters, with some private stations also
other information, changing every 2 to 5 seconds.
Pressing the RDS Display button enables
you to cycle through the various data types in the
following sequence:

OPERATION 15

Operation

• The Station name (or other Program informa­tion with some private stations).

• The station’s frequency.

• The Program Type (PTY) as shown in the fol­lowing list in this manual.

• A “text” message (RT) containing special infor­mation from the broadcast station. Note that this
message will scroll across the display to permit
messages longer than the eight positions in the
display. Depending on signal quality it may take
up to 30 seconds for the text message to appear,
in the meantime the word TEXT will flash in
the display when RT is selected.

• The current time of day (CT) as transmitted by
the station. It may take up to two minutes for the
time to appear, in the meantime the word
TIME will flash in the display when CT is
selected. Note that the accuracy of the time mes­sage is set by the radio station, not the HK 3470
RDS.

• Some RDS stations may not choose to include
some of these additional features. If the data
required for the selected mode is not being trans­mitted, the Information Display
a NO PTY, NOTEXT or NOTIME
message after the individual time out.

• In any FM mode the RDS function requires a
strong enough signal for proper operation. If you
receive a partial message or see any RDS indica­tor going on and off,try slowly adjusting the
antenna to improve the signal strength or tune
to another, stronger, RDS station.

Program Search (PTY)

A major benefit of RDS is its ability to encode
broadcasts with Program Type (PTY) codes that

Using the Remote Control

It is convenient to think of the functions of the
remote control buttons in terms of “pages”,
where each source device (e.g., CD player) rep­resents its own page of remote functions. The
result is that some of the keys will perform dif­ferent functions depending upon which device
page has been selected prior to pressing the
key. Device pages are selected by pressing the

Programming the Remote Control

Although the remote control is prepro­grammed at the factory to operate compatible
Harman Kardon CD recorders, players and
changers, and cassette decks, you may program
the remote with control codes that operate other
devices.

Not all of the buttons on the HK 3470 remote
control may be programmed. If you attempt to
“learn” a code into a button not shown in the
table below, you may experience undesired
responses to remote commands, or lose the abil­ity to perform some functions using the remote
control.

You may program remote buttons only on these
pages: AUX,TAPE 2, TAPE MON,and CD. Codes
may not be programmed to the pages for Phono,
AM or FM.

Only the buttons shown in this table with an
“X” may be programmed.

Operation

Programming the Remote Buttons
Is a Simple Procedure
Step 1: Place the HK 3470 remote control and

the remote control for the other device (e.g.,
compact disc player) so that their infrared
transmitter windows face each other at a dis­tance of about 0.5 to 1 cm.

Step 2: Simultaneously press the Learn button

√ and the Source Selector ç that corre­sponds to the device whose codes you are try­ing to program (e.g., press the CD button
along with the Learn button). The LED

Indicator Ω will blink twice and remain lit.

Step 3: Press and release the button on the HK

3470 remote that you wish to program. Make
sure that it is one of the programmable but­tons listed in the table on page 18. The LED

Indicator Ω will blink once and remain lit.

Step 4: Press and hold the button on the other

device’s remote whose code you wish to
program into the HK 3470 remote until the
LED Indicator Ω blinks three times and
remains lit, then release the button on the
other remote.

If the LED Indicator Ω flickers for five sec-
onds instead of blinking three times and
remaining lit, the learning operation was
unsuccessful. Try the procedure again,starting
from Step 2, making sure that the transmitter
windows of the two remotes face each other,
and that the button you are trying to program
on the HK 3470 remote is listed in the table
on page 18.
Also varying the distance between both
remotes may help.

Step 5: To program additional buttons, repeat

Steps 2 through 4.

Step 6: To exit the learning mode, either press

the Learn button √ once, or wait 20 seconds
for the remote to automatically return to nor­mal operation.

Resetting One Key to Default Setting

When a new code is programmed into the
remote, it overwrites the previous code for that
button on that page. However,should you make
a mistake,it is possible to reset any button to its
factory default using the following procedure:

Step 1: Enter the learning mode by simultane-

ously pressing any of the Device buttons ç
and the Learn button √.

Step 2: Press and release the particular device

button for the page containing the key you
wish to reset. The LED Indicator Ω will
blink once and remain on.

Step 3: Use the Numeric Keys ˚ to enter the

numbers “777”. The LED Indicator Ω will
blink for each entry.

Step 4: Press and release the button that you

wish to reset. The LED Indicator Ω will
blink three times to indicate that the button
has been reset to the factory default code.

Step 5: You may repeat Step 4 to reset the

codes for other keys.If you wish to reset the
codes for an entire device page, see below.

Step 6: To exit the learning mode, either press

the Learn button √ once, or wait 20 seconds
for the remote to automatically return to nor­mal operation.

Resetting an Entire Device Page

If you wish to reset all of the codes for a particu­lar device, you need not individually reset every
button on that page of the remote.This is the
procedure for resetting the codes on a particular
page.

Step 1: Enter the learning mode by simultane-

ously pressing any of the Device buttons ç
and the Learn button

Step 2: Press and release the particular device

button for the page you wish to reset. The
LED Indicator Ω will blink once and remain
on.

Step 3: Use the Numeric Keys ˚ to enter the

numbers “888”. The LED Indicator Ω will
blink for each entry.

Step 4: The LED Indicator Ω will remain on

for one second, and then blink three times to
indicate that it has reset the group of keys for
the selected device page.That device page will
now operate the factory default set of codes.

Resetting the Entire Remote

It is also possible to completely reset all of the
programmed codes in the remote to the factory
default settings. Use the following procedure:

Step 1: Enter the learning mode by simultane-

ously pressing any of the Device buttons ç
and the Learn button √.

Step 2: Press and release any device button

other than PHONO,AM or FM.The LED

Indicator Ω will blink once and remain on.

Step 3: Use the Numeric Keys ˚ to enter the

numbers “999”. The LED Indicator Ω will
blink for each entry.

Step 4: The LED Indicator Ω will remain on

for five seconds, and then blink three times to
indicate that it has reset all of the keys on the
remote.The entire remote will now operate
the factory default set of codes.

Memory Backup

This product is equipped with a memory backup
system that preserves tuner presets if the unit is
accidentally unplugged, turned off completely
with the Main Power switch
to a power outage.The unit’s memory is stored in
an EEPROM, and thus the HK 3470 will retain
information such as programmed presets without
being connected to a main power source virtually
indefinitely.

or subjected

Processor Reset

In the rare case where the unit’s operation or the
displays seem abnormal, the cause may involve
the erratic operation of the system’s memory or
microprocessor.

To correct this problem, first unplug the unit from
the AC wall outlet and wait at least three min­utes.After the pause,reconnect the AC power
cord and check the unit’s operation.If the system
still malfunctions, a system reset may clear the
problem.

To reset the system, first turn the HK 3470 off by
pressing the Main Power Switch
releasing it so that it extends out beyond the
front panel and the word “OFF” is visible in red
at the top of the switch.

Next, press and hold the T-M o n and CD Input
Selector buttons
ONLY. While holding these buttons in, press the

Main Power Switch

that the button is flush with the front panel.

The Main Information Display will briefly show
the word RESET, you can release the buttons
pressed now, the unit will return to Standby
mode.

Note that when the system is reset in this fash­ion, all tuner presets will be lost and must be
reentered.

If the system is still operating incorrectly,there
may have been an electronic discharge or severe
AC line interference that has corrupted the mem­ory or microprocessor.

If these steps do not solve the problem, consult
your dealer or an authorized Harman Kardon
service center.
