INSTALLATION AND CONNECTIONS

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

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 

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

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!
