12 INSTALLATION AND CONNECTIONS

System Installation
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 inter-
connect 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 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.

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 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.

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 ¤.

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 £.

6. Assemble the AM Loop Antenna supplied
with the unit as shown below. Connect it to the
AM screw terminals ¡.

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.

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.

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.

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.

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.

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 “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.

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.

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 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.

13 INSTALLATION AND CONNECTIONS

System and Power Connections
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
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 ¢.

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.

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 fi 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 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.

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 fi jacks to the inputs of the external
device, and the outputs of the device to the
Main In ‹ jacks.

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.

AC Power Connections
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

1 is in the “OFF” position.

Speaker Placement
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.

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-
frequency 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 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 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.

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!
