Installation and Configuration
Your new Harman Kardon receiver is
designed to provide the best reproduction
from both movies and musical pro-
grams. To assure that the unit operates to
its fullest capability, it is important that
you spend a few minutes to properly
install and configure all of the elements
in your new system. Some, or all of the
following steps will apply to your system,
depending on the equipment in use. If
you have any questions concerning the
installation of this product consult your
local dealer, or contact the Harman
Kardon web site at

System Component Connections
IMPORTANT SAFETY NOTE:
Many
products feature automatic turn on cir-
cuitry which may accidentally be activated
when making connections. For your own
safety and to prevent damage to speakers,
amplifiers and other components we
strongly recommend that all equipment
power be turned off at the
Main Power
Switch
1
, or that AC power cords be
unplugged when any system connections
are made or changed.
Using high-quality interconnect cables,
connect all source components to the
appropriate input jacks on the rear
panel. When connecting audio recorders
and VCRs it is important to make certain
that the PLAY/OUT jacks on the recorders
are connected to the
PLAY
jacks on the
AVR40, and that the RECORD/IN jacks of
the recorders are connected to the
REC
jacks on the AVR40.
Assemble the supplied AM loop antenna
as shown below and connect it to the
AM
ANTENNA Terminals
f
.
It may be necessary to rotate the antenna
or change its position to achieve the best
AM reception. Connect an FM antenna to
the
FM ANTENNA Terminal
g
. A
300-ohm to 75-ohm adapter may be
required for some antennae.
If you are using the AVR40 to switch
video inputs, connect the
Monitor
out-
put
‚
to a video input on your TV or
projector.
The rear panel accessory outlets on the
AVR40 may be used to power low current
devices such as CD players or tape decks.
The
SWITCHED Accessory AC
Power Outlets
fl
are activated only
when the AVR40 is turned on. The
UNSWITCHED Accessory AC
Power Outlets
fi
may be used with
VCRs, as the power to these outlets is live
as long as the AVR40 remains connected
to an AC power source.
CAUTION:
The total power load for all
products connected to the accessory out-
lets must not exceed 100 watts. Do not
use them for high current devices such as
power amplifiers.
If the AVR40’s front panel remote sensor
35
is blocked by cabinet doors you may
still operate the unit via remote control
with the use of an optional external
remote sensor. Connect the output of the
sensor to the rear panel

components.
Speaker Selection and Placement
Depending on the type of center channel
speaker in use and your viewing device,
place the center speaker directly above or
below your TV.
Once the center channel speaker is
installed, position the left and right front
speakers so that they are as far away
from one another as the center channel
speaker is from the preferred listening
position. Ideally, the front channel
speakers should be placed so that their
tweeters are no more than 24
″
higher
or lower from the tweeter in the center
channel speaker.
Depending on the specifics of your room
acoustics and the type of speakers in use,
imaging may be improved by moving the
front left and right speakers slightly for-
ward of the center channel speaker. If
possible, adjust all front loudspeakers so
that they are aimed at ear height when
you are seated in the listening position.
Using these guidelines, you may find that
it takes some experimentation to find the
correct location for the front speakers in
your particular installation. Don’t be
afraid to move things around until the
system sounds correct. Optimize speaker
locations so that pans across the front of
the room sound smooth, and that sounds
from all speakers appear to arrive at the
listening position at the same time with-
out delay from the center speaker as
opposed to the left and right speakers.
