Harman-Kardon AVR 510 - Manual (Page 15)

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.
Audio Equipment Connections
We recommend that you use high-quality inter-
connect cables when making connections to
source equipment and recorders to preserve the
integrity 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 possibility of acciden-
tally 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 analog Play/Out jacks of a cas-
sette deck, MD, CD-R or other audio recorder to
the Tape Input jacks ¡. Connect the analog
Record/In jacks on the recorder to the Tape
Output jacks ™ on the AVR 510.
3. Connect the output of any digital sources
to the appropriate input connections on the
AVR 510 rear panel. Note that the Optical
and Coaxial digital inputs
#% may
be used with a Dolby Digital or DTS source or
the output of a conventional CD or LD player’s
PCM (S/P-DIF) output.
4. Connect the coaxial or optical Digital Audio
Outputs
on the rear panel of the AVR 510 to
the matching digital input connections on a CD-R
or MiniDisc recorder.
5. Assemble the AM Loop Antenna supplied
with the unit as shown below. Connect it to the
AM and GND screw terminals ¢ .
6. Connect the supplied 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 antenna or
connection uses 300-ohm twin-lead cable, you
must use the 300-ohm-to-75-ohm adapter sup-
plied with the unit to make the connection.
7. Connect the front, center and surround
speaker outputs fi to the respective speakers.
To ensure 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 the
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 recom-
mend that you use cables with an AWG equiva-
lent 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 stan-
dards. 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 build-
ing codes in your area.
When connecting wires to the speakers, be cer-
tain to observe proper polarity. Remember to
connect the “negative” or “black” wire to the
same terminal on both the receiver and the
speaker. Similarly, the “positive” or “red” wire
should be connected to like terminals on the
AVR 510 and speaker.
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 ensure 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 pro-
ceeding, or consult the speaker’s manufacturer.
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 surround-left and surround-right speakers,
even if the speakers are a different distance
from the AVR 510.
8. Connections to a subwoofer are normally
made via a line-level audio connection from the
Subwoofer Output ‹ to the line-level input
of a subwoofer with a built-in amplifier. When a
passive subwoofer is used, the connection first
goes to a power amplifier, which will be con-
nected to one or more subwoofer speakers. If
you are using a powered subwoofer that does
not have line-level input connections, follow the
instructions furnished with the speaker for con-
nection information.
