Installation And Connections - Harman Kardon HK3470 Owner's Manual

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 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 send-
ing 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 . Connect the Record/In
jacks on the recorder to the Tape Monitor
Rec. 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, 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, satel-
lite 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 sys-
tem. 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 resolu-
tion, 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 select-
ing 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 mm 2 .
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
smaller due to the power loss and degradation
in performance that will occur.
Cables that are run inside walls should have the

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 configu-
ration. To assure proper phase, and optimal per-
formance, 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 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 sub-
woofer is used, these connections will be made
to the optional amplifier that powers the sub-
woofer. If the (passive) subwoofer or Sub/Sat
system has only speaker-level inputs and out-
puts, connect the Speaker 1 terminals
speaker-level inputs on the subwoofer, and then
connect the speaker-level outputs on the sub-
woofer to your main left and right speakers,
following the instructions provided with the
subwoofer.
