Installation And Connections - Harman Kardon HK 3370 Owner's Manual

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, 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 3370. 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, 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
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
(75 ohm) 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 anten-
na 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 and Output Connections
To assure 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 this
receiver, the type of speakers you use, personal
preferences and other factors. Your dealer or
installer is a valuable resource to consult 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 14 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 terminal on the HK 3370 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 front left and front right or sur-
round left and surround right speakers, even if
the speakers are a different distance from the
HK 3370.
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 proceeding, 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 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 jack for the connection.
When a passive subwoofer is used, these con-
nections will be made to the optional amplifier
that powers the subwoofer.
