Installation and Configuration
NOTE: The Balance control
$
should
be at the midpoint, or “12 O’clock” posi-
tion when calibrating the system.
Press the Calibrate button
q
on the
remote again and note that a test tone
will be heard from the left front speaker.
Press the Speaker
›
button
s
and
observe that the test noise will move first
to the center speaker, then to the front
right speaker and then to the rear speak-
ers as you press the button. This is a good
opportunity to check for proper speaker
connections by listening to the test noise
and checking to see that it is coming
from the speaker location indicated in
the front panel display.
Press the Speaker
‹
or
›
buttons
s
on the remote to return the test tone to
the front left speaker and make any fine
tuning to the volume setting using the
Volume control
Ùl
. Next, press the
Speaker
›
button
s
to move the test
noise to the center channel. Use the
Level + or Level - buttons
t
so that
the sound level appears identical to the
left front channel.
Press the Speaker
›
button
s
again
to listen to the front right channel for
reference purposes, and then press the
Speaker
›
button
s
so that the test
noise moves to the rear channel. Use the
Level + or Level - buttons
t
to
adjust the volume level so that it appears
identical to the other channels.
After making initial adjustments to the
system it is a good idea to repeat the pro-
cedure again, switching the channels
more quickly in order to hear and adjust
for any differences between the channels.
When the procedure is concluded the
sound from all channels should be as
equal as possible.
To conclude the adjustment press the
Calibrate button
q
on the remote, or
any input source selection button on the
remote or front panel.
NOTE: It is also possible to adjust the
channel levels while listening to any
input source by pressing the Calibrate
button
(
and then adjusting the levels
using the main Volume control
Ùl
and the Level + or - buttons
t
to
change the levels and the SPKRS
‹›
buttons
s
to change the channel being
adjusted. During this procedure, however,
all channels will be heard simultaneously.
Delay Setting
Delay time adjustment enables you to
adjust the timing between signals at the
front and surround channels.
The factory setting is appropriate for
most rooms, but in some instances the
presence of an abundance of hard
(reflective) room surfaces such as win-
dows and wood floors, or soft (absorbent)
surfaces such as thick carpeting, acousti-
cal tiles and some furnishings may cre-
ate an unpleasant effect. These surfaces,
in conjunction with the size of the room,
the height of the ceiling and other
design aspects may cause the arrival of
surround channel sounds to become dis-
connected from front channel sounds.
To adjust the delay time press the Delay
button
*
on the front panel. The time
shown in the Information Display
¯
should be as close as possible to the
result of the following formula or to your
personal preference.
1. Measure the distance from the
listening/viewing position to the front
speakers.
2. Measure the distance from the listen-
ing/viewing position to the surround
speakers.
3. Subtract the distance to the rear speak-
ers from the distance to the front speakers
and add 15. The resulting number is the
ideal delay time for your room. For exam-
ple, if the front speakers are 10 feet away
and the rear speakers are 5 feet away, the
formula will be “10-5+15=20.” Thus, the
correct delay time in this room would be
20 ms.
Center Channel Mode
This setting enables you to tailor the out-
put of the AVR40 to the type of center
channel speaker in use. Press the Center
button
^
until the front panel display
indicates the type of center speaker used
in your listening environment.
LG CENTR: Choose this setting if your
center channel speaker is a traditional
full range speaker capable of extended
bass response.
SM CENTR: Choose this setting if
your center channel speaker is a smaller
satellite type speakers with limited bass
response.
NO CENTR: Choose this setting if no
center speaker is installed.
Rear Channel Setting
This setting tells the AVR40 if rear chan-
nel speakers are in use. Press the Rear
button
&
until the front panel display
indicates the appropriate condition for
your listening system.
REAR: Choose this setting if rear chan-
nel speakers are installed.
NO REAR: Choose this setting if rear
speakers are not in use.
