System Installation
After unpacking the unit and placing it on a solid sur-
face 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 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 3475. 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 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. 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 and Output Connections
To ensure 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 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 recom-
mend that you use a cable constructed of fine, multi-
strand 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 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 terminals
on the HK 3475 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 3475.
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 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 fl 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.
