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 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.

Description and Features  
Harman Kardons HK 3470 is the worlds 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.

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 users 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.

Display. Release the button and note that the  
tuner will briefly stop at each active station and  
add a preset number to the memory. If the FM  
tuner finds fewer than 30 FM stations with  
acceptable signal strength, the Auto Preset tun-  
ing will scan two more cycles or until the  
remaining vacant preset memory spaces have  
been filled with those found in the first scan.  
The scan will stop when all 30 preset memory  
spaces have been filled or when three scans

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 speakers 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 speakers 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 to the line-level  
inputs of the subwoofer. When the subwoofers  
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 £.  
12 INSTALLATION AND CONNECTIONS  
 
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 manufacturers 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 units 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 3470s 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 and  
Main In jacks on the rear panel. Keep the  
jumpers in a safe place should they be needed  
at a later time.  
frequency drivers, are aimed at ear height  
when you are seated in the listening position.  
Left Front  
Speaker  
Right Front  
Speaker  
Using high-quality audio interconnect cables,  
connect the Preamp Out jacks 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  
Jumper Pins and connecting the Preamp  
Out jacks to the inputs of the external  
device, and the outputs of the device to the  
Main In jacks.

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  
Programming the Remote Control  
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.  
Although the remote control is prepro-  
grammed 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.  
Only the buttons shown in this table with an  
Xmay be programmed.

Operation  
Programming the Remote Buttons Is a  
Simple Procedure  
Resetting One Key to Default Setting  
Step 3: Use the Numeric Keys ˚to enter  
the numbers “888”. The LED Indicator Ω  
will blink for each entry.  
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 but-  
ton to its factory default using the following  
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 one-half inch.  
Step 4: The LED Indicator 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.  
Step 2: Simultaneously press the Learn button  
and the Source Selector çthat corre-  
sponds to the device whose codes you are  
trying to program (e.g., press the CD button  
along with the Learn button). The LED  
Step 1: Enter the learning mode by simultane-  
ously pressing any of the Device buttons ç  
and the Learn button .  
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 2: Press and release the particular device  
button for the page containing the key you  
wish to reset. The LED Indicator will  
blink once and remain on.  
Indicator will blink once 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 program-  
mable buttons listed in the table on page  
17. The LED Indicator will blink once  
and remain lit.  
Step 1: Enter the learning mode by simultane-  
ously pressing any of the Device buttons  
çand the Learn button .  
Step 3: Use the Numeric Keys ˚to enter  
the numbers “777”. The LED Indicator Ω  
will blink for each entry.  
Step 2: Press and release any device button  
other than PHONO, AM or FM. The LED  
Indicator will blink once and remain on.  
Step 4: Press and release the button that you  
wish to reset. The LED Indicator will  
blink three times to indicate that the button  
has been reset to the factory default code.  
Step 4: Press and hold the button on the other  
devices remote whose code you wish to  
program into the HK 3470 remote until the  
LED Indicator blinks three times and  
remains lit, then release the button on the  
other remote.  
Step 3: Use the Numeric Keys ˚to enter  
the numbers “999”. The LED Indicator Ω  
will blink for each entry.  
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 4: The LED Indicator 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 oper-  
ate the factory default set of codes.  
If the LED Indicator flickers for five sec-  
onds instead of blinking three times and  
remaining lit, the learning operation was unsuc-  
cessful. Try the procedure again, starting from  
Step 2, making sure that the transmitter win-  
dows 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 17.  
Step 6: To exit the learning mode, either press  
the Learn button once, or wait 20 sec-  
onds 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 partic-  
ular device, you need not individually reset  
every button on that page of the remote. This is  
the procedure for resetting the codes on a par-  
ticular page.  
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 sec-  
onds for the remote to automatically return  
to normal operation.  
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 will blink once and  
remain on.  
18 OPERATION  
 
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 units 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 units 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 units operation or  
the displays seem abnormal, the cause may  
involve the erratic operation of the systems  
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.
