Installation and Setup

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 con-
nected to the like terminal on the AVR75
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 configuration. 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.

7. Connections to a subwoofer are made
via a line level audio connection from
the 

⁄

to the line

level input of a subwoofer with a built-in
amplifier. If a passive subwoofer is used,
the connection first goes to a power
amplifier, which will be connected to one
or more subwoofer speakers.

Video Input and Output Connections
Video connections are made in a similar
fashion to those for audio components.
Again, the use of high-quality intercon-
nect cables is recommended to preserve
signal quality.

1. Connect the VCR’s audio, video and 
S-Video OUT jacks to the 

jacks

d i

on the rear panel. The audio, video

and S-Video IN jacks on the VCR should
be connected to the 

jacks 

e h

on the AVR75.

2. Connect the audio and video outputs
of a satellite receiver, cable TV converter
or television set or any other video source
to the 

jacks 

ª

.

3. Connect the audio, video and S-Video
outputs of a DVD or laser disc player to
the 

jacks 

•

.

4. Connect the 

f g

jacks on 

the receiver to the video, or S-Video
inputs, of your television monitor or
video projector. 

5. As the AVR75 does not mix or change
between standard composite video and 
S-Video signals, both monitor connec-
tions must be made if you use both
signal systems.

Note: The on-screen menus are visible
on the composite video output only.

The AVR75 is designed for flexible use
with external control components and
power amplifiers. These connections are
easy to make during an initial installa-
tion, or at a later date should you choose
to upgrade your system.

Remote Control Extension
If the receiver is placed behind a solid or
smoked glass cabinet door, the obstruc-
tion may prevent the remote sensor from
receiving commands. In this event, an
optional remote sensor may be used.
Connect the output of the remote sensor
to the 

jack 

b

. 

If other components are also prevented
from receiving remote commands, only
one sensor is needed. They may use this
unit’s sensor or a remote eye by running
a connection from the 

jack 

c

to the Remote In jack on

Harman Kardon or other compatible
equipment. 

If desired, optional external power audio
power amplifiers may be used with the
AVR75. Connections to these amplifiers
are made by using audio interconnect
cables connected to both the 

‚

on the rear panel and 

the audio input jacks of the external
amplifiers.

AC Power Connections
This unit is equipped with two accessory
AC outlets. They may be used to power
accessory devices, but they should not be
used with high-current draw equipment
such as power amplifiers. The total power
draw may not exceed 50w to each outlet.

The 

fi

outlet will receive

power only when the unit is on. This is
recommended for devices that have no
power switch, or a mechanical power
switch that may be left in the “ON” 
position.

Note: Devices with electronic power
switches may only go into a Standby
mode when plugged in here.

The 

fl

outlet will receive

power as long as the unit is plugged into
a powered AC outlet.

Finally, when all connections are com-
plete, plug the power cord into a non-
switched 120-volt AC wall outlet. You’re
almost ready to enjoy the AVR75!
