Installation and Configuration

NOTE: The 

control 

$

should

be at the midpoint, or “12 O’clock” posi-
tion when calibrating the system.

Press the 

button 

q

on the

remote again and note that a test tone
will be heard from the left front speaker.
Press the 

›

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 

‹

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

control 

Ùl

. Next, press the

›

button 

s

to move the test

noise to the center channel. Use the

buttons 

t

so that

the sound level appears identical to the
left front channel.

Press the 

›

button 

s

again

to listen to the front right channel for
reference purposes, and then press the

›

button 

s

so that the test

noise moves to the rear channel. Use the

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

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 

button 

(

and then adjusting the levels

using the main 

control 

Ùl

and the 

or

buttons 

t

to

change the levels and the 

‹ ›

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 

button 

*

on the front panel. The time

shown in the 

¯

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 

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 

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.
