12 INSTALLATION AND CONNECTIONS
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 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 interconnect
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 practice to unplug the
unit from the AC wall outlet.This prevents any possibil-
ity of accidentally sending audio or transient signals to
the speakers that may damage them.
1. Connect the analog output of a CD player to the
CD Audio Inputs £.
NOTE: When the CD player has both fixed and vari-
able 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
¢. Connect the Record/In jacks
on the recorder to the
Tape Monitor Out Jacks ∞
on the HK 3380.When the tape deck connected to
these jacks is a three-head unit or has off-head play-
back, it will be possible to monitor the output of the
source being recorded.
3. Connect the audio and/or video outputs of a
second audio recorder,VCR or other line-level audio
device to the
Video 1 Audio/Video Input Jacks §.
If a recorder is used, connect its Rec/In jacks to the
matching outputs
¶.
4.The audio and/or video outputs of any electronics
product with a line-level output, such as a TV set,
satellite receiver or DVD, may be connected to the
Video 2 and Video 3 Audio/Video inputs •ª.
NOTE: In order to view the video signals of any
devices connected to the
Video 1 §,Video 2 •
or Video 3 ª Video Inputs, you will need to
connect the
Video Monitor Output · jack to
the composite video input of your TV or other video
display device.
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. Connect it to the
AM Screw
Terminals
a.
7. Connect an FM antenna to the
FM (75-ohm)
Connection
b.The FM antenna may be an external
roof antenna, an inside powered or wire lead antenna
or a connection from a cable TV system. If the antenna
or connection uses 300-ohm twin-lead cable, you must
use an optional 300-ohm-to-75-ohm adapter to
make the connection. Note that you will
not be able
to view any video signal using the
FM Antenna
Connection
b, even if you connect your cable
television system to it.
Speaker and Output Connections
To assure that all the audio signals are carried to your
speakers without loss of clarity or resolution, we sug-
gest that you use high-quality speaker cable. Many
brands of cable are available, 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 recom-
mend that you use a cable constructed of fine, multi-
strand 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 recommend 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 “positive” or
“red” wire should be connected to the like terminal on
the HK 3380 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 3380.
NOTE: While most speaker manufacturers adhere to
an industry convention of using black terminals for
negative and red ones for positive, some manufactur-
ers may vary from this configuration. To assure proper
phase, and optimal performance, consult the identifica-
tion 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.
You may 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 sub-
woofer.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.
