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.

I VMAx Processing Mode – Exclusive to

Harman Kardon Receivers

I Phono Input Section

I Speaker 1/Speaker 2 Outputs for High-

Quality Sound in Two Locations

While sophisticated systems are hard at work

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.

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.

I Subwoofer Outputs

If you have any questions about this product, its

installation or operation, please contact your

dealer, your best local source of information.

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.

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.

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

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.

Safety Information

Do Not Open the Cabinet

I Avoid moist or humid locations.

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.

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.

I 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 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

unit.

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.

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-

trode.

Unpacking

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.

Moving the Unit

Before moving the unit, be certain to discon-

nect any interconnection cords with other com-

ponents and make certain that you disconnect

the unit from the AC outlet.

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.

Important Information for the User

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

NOTE TO CATV SYSTEM INSTALLER: This

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.

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.

Installation Location

I 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.

following measures:

I 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

the cabinet. Under some circumstances a fan

may be required.

I Reorient or relocate the receiving antenna.

I Increase the separation between the equip-

ment and receiver.

I Connect the equipment into an outlet on a

circuit different from that to which the

receiver is connected.

Installation and Connections

System Installation

6. Assemble the AM Loop Antenna supplied

with the unit as shown below. Connect it to the

AM screw terminals ¡.

When connecting wires to the speakers,

be certain to observe proper polarity.

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.

Remember to connect the “negative” or

“black” wire to the same terminal on the

receiver and the speaker. Similarly, the “posi-

tive” 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.

Audio Equipment Connections

We recommend that you use high-quality inter-

connect cables when making connections to

source equipment and recorders to preserve the

quality of the signals.

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

TV system. Note that if the antenna or connec-

tion uses 300-ohm twin-lead cable, you must

use the 300-ohm-to-75-ohm adapter supplied

with the unit to make the connection.

When making connections to audio source

equipment or speakers it is always a good prac-

tice to unplug the unit from the AC wall outlet.

This prevents any possibility of accidentally

sending audio or transient signals to the speak-

ers that may damage them.

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 config-

uration. 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 pro-

ceeding, or consult the speaker’s manufacturer.

Speaker and Output Connections

To ensure that all the audio signals are carried

to your speakers without loss of clarity or reso-

lution, we suggest that you use high-quality

speaker cable. Many brands of cable are avail-

able, 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.

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.

Connect the speakers using the following steps:

1. Connect the main speakers to the Speaker 1

terminals ‡.

2. Connect the Play/Out jacks of a cassette

deck, CDR, MD or other audio recorder to the

Tape Monitor In jacks ª. Connect the

Record/In jacks on the recorder to the Tape

Monitor Out jacks ‚ on the HK 3470. When

the tape deck connected to these jacks is a

three-head unit or has off-head playback, it will

be possible to monitor the output of the source

being recorded.

Regardless of the brand of cable selected, we

recommend that you use a cable constructed of

fine, multistrand copper with a gauge of

AWG14 or smaller. Remember that in specifying

cable, the lower the number, the thicker the

cable.

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 ﬂ 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. If the subwoofer 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. When

a passive subwoofer is used, these connections

will be made to the optional amplifier that

powers the subwoofer.

Cable with a gauge of 16 may be used for

short runs of less than ten feet. We do not rec-

ommend that you use cables with an AWG

equivalent of 18 or higher due to the power

loss and degradation in performance that will

occur.

3. Connect the output of a second audio

recorder, CDR, VCR or other line-level audio

device to the Tape 2 Play/In jacks ⁄. If a

recorder is used, connect its Rec/In jacks to the

matching Tape 2 Record outputs ¤.

Cables that are run inside walls should have

the appropriate markings to indicate listing

with UL, CSA or other appropriate testing

agency standards. Questions about running

cables inside walls should be referred to your

installer or a licensed electrical contractor who

is familiar with the NEC and/or the applicable

local building codes in your area.

4. The 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

§. To insure that the phono playback is noise-

free, connect the ground wire from the tone-

arm to the Phono Ground terminal £.

Installation and Connections

System and Power Connections

Alternatively, you may connect the external

device to the Tape Monitor Loop. Connect the

Tape Monitor Record/Out jacks ‚ to the

inputs of the external device, and connect the

outputs of the device to the Tape Monitor

Play/In jacks ª.

To optimize the sound field, or to suit your lis-

tening 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 HK 3470 is designed for flexible use with

external control components and power ampli-

fiers. These connections are easy to make dur-

ing an initial installation, or at a later date

should you choose to upgrade your system.

Remote Control Extension

AC Power Connections

If the receiver is placed behind a solid or

smoked glass cabinet door, the obstruction may

prevent the remote sensor from receiving com-

mands. In this event, an optional remote sensor

may be used. Connect the output of the remote

sensor to the Remote IR In jack ¢.

The Accessory Outlets · receive power as

long as the receiver is turned on. Power to

these outlets is removed when the unit is in the

Standby mode, or when the Main Power

Switch 1is in the “OFF” position.

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 sub-

woofer 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.

Speaker Placement

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 ∞ to the Remote In jack

on Harman Kardon or other compatible equip-

ment.

For optimal listening enjoyment, and for sound-

field reproduction that best re-creates the origi-

nal 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 pre-

ferred listening spot at the third point of the tri-

angle. The distance between each speaker and

the listener should be identical.

External Audio Power Amplifier

Connections

If desired, an optional, external amplifier may

be used in place of the HK 3470’s internal

power amplifier.

For example, if the speakers are 10 feet from

one another, each of the speakers should opti-

mally be placed so that they are also 10 feet

from the listener. It is also desirable to place

speakers so that their tweeters, or high-

Finally, when all connections are complete, plug

the power cord into a nonswitched 120-volt AC

wall outlet. You’re ready to enjoy the HK 3470!

To connect an external power amplifier, first

remove the Pre-Out/Main-In Jumper Pins

› that connect the Preamp Out ﬁ and

Main In ‹ jacks on the rear panel. Keep the

jumpers in a safe place should they be needed

at a later time.

Right Front

Speaker

Using high-quality audio interconnect cables,

connect the Preamp Out jacks ﬁ to the input

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.

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.

If you wish to use external processing equip-

ment, such as an equalizer, you may connect

the device to the preamp-out and main-in jacks

by removing the Preamp-Out/Main-In

Basic Operation

The HK 3470 is simple to operate, and very sim-

ilar to stereo receivers you may have used in

the past. This section will explain the use of

several features that may be new to you.

• To program the HK 3470 for automatic turn-

off, press the Sleep button on the front panel

(or remote ©. Each press of the button will

increase the time before shutdown in the fol-

lowing sequence:

adjust the Bass Ó, Treble Ôand Balance

controls to suit your listening tastes.

The sleep time will be displayed in the Main

Information Display Ûand it will count

down until the time has elapsed.

• Adjust the volume to a comfortable level

using the front panel Volume Control Òor

remote Master Volume Up/Down πbut-

tons. The volume level is displayed by the posi-

tion of the Volume Indicator Ú. Think of the

Volume Control knob Òas the face of a

clock, with the Volume Indicator Úindicat-

ing the hour. The HK 3470 is playing at the

minimum volume level when the Volume

Indicator Úpoints to 7 o’clock; when the

Volume Indicator Úpoints to 12 o’clock

(straight up), the HK 3470 is playing at the

maximum volume level. It is important that you

make sure never to exceed this maximum vol-

ume level at any time, in order to avoid possi-

ble damage to your loudspeakers due to “clip-

ping”, a type of distortion that is not audible to

the human ear until it is severe enough to per-

manently damage most loudspeakers. It is also

possible, depending upon the program material,

for clipping to occur at volumes below the max-

imum volume level.

When the programmed time has elapsed, the

unit will automatically turn off. Note that the

front panel display will dim to one-half bright-

ness when the Sleep function is programmed.

To cancel the Sleep function, press the Sleep

Operation

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.

The Main Information Display will briefly show

the word RESET, and then return to normal

operation.

Memory Backup

This product is equipped with a memory backup

system that preserves tuner presets and system

configuration information if the unit is acciden-

tally unplugged or subjected to a power out-

age. 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.

Note that when the system is reset in this fash-

ion, all tuner presets will be lost and must be

reentered.

If the system still does not respond, it may be

necessary to perform a complete reset. To reset

the system, first turn the HK 3470 off by press-

ing the Main Power Switch 1and then

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.

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.

Processor Reset

If these steps do not solve the problem, consult

your dealer or an authorized Harman Kardon

service center.

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.

Next, press and hold the T-Mon and CD Input

Selector buttons 9#on the front panel

ONLY. While holding these buttons in, press the

Main Power Switch 1in until it latches, so

that the button is flush with the front panel.
