best to use the factory settings for initial
listening sessions. See the Advanced
Features section later in this manual for
information on delay settings.

The remaining item to be adjusted before
normal use of the AVR75 is adjustment 
of the output levels. Correct adjustment
of these settings is critical to proper oper-
ation of the receiver in all surround
modes, and particularly when Dolby
Digital sources are being played.

1. To set the output levels press the

button 

j

to call up the main

menu (see figure #1)if it is not already
on the screen, and then press the the 

¤

button 

i

until the on-screen cursor is

pointing to 

TEST TONE

. Press 

j

to move to the 

TEST TONE

menu.

2. When you press 

you will

immediately hear a test noise from the
front left speaker. The on-screen display
will change to a graphic representation
of each of the speakers in your room,
with one speaker position blinking (see
figure #5). That speaker is the one whose
level is being set. 

NOTE: This procedure will only operate
if the AVR75 is in the

PRO LOGIC

,

AC-

3

,

MOVIE

or

DOLBY 3 STEREO

modes. If the test tone cannot be selected,
check to see which surround mode is
indicated in the front panel display. If it is
not one of the modes mentioned above,
select one of the correct modes using the

y

, and then move

the cursor to 

TEST TONE

to restart the

procedure.

3. While seated in the primary listening
position, you should hear a test noise 
signal from the left front speaker. You
may leave the volume setting where it is,
or raise it to an appropriate level using
the

⁄

or 

¤ 

buttons 

n

on the remote. For a more precise cali-
bration, we recommend that you use a
sound pressure level meter.

4. Press the 

›

or 

button 

i m

on the remote. Note that the

sound should now come from the Center
Channel speaker if one is installed, and
the icon for that speaker will flash on 
the screen. Use the 

⁄

or 

¤

buttons 

n

on the remote to change the

level of the test noise so that it appears to
be equal in level to the Front Left speaker. 

5. Press the 

›

or 

button 

i m

again, and repeat the procedure

for the Front Right, Surround Right and

Surround Left channels. Each time, use
the 

⁄

or 

¤ 

buttons 

n

on

the remote to change the volume level 
so that all speakers match, and the 

›

button 

i

to move to the next channel. 

NOTE: This test also serves as an oppor-
tunity to verify that all speakers are 
properly connected. If the sound from a
speaker location does not match the
location shown on the video and front
panel displays, turn the AVR75 off and
check the speaker wiring to make certain
that the speaker is connected to the 
correct output terminals.

6. When all speakers appear to have an
equal volume, press the 

‹

button 

i

on the remote and then 

j

to

complete the procedure.

NOTE: You may also check the output
levels at any time by pressing the 

button 

l

. When the on-screen

display is also activated by pressing 

k

, you will see the speaker icons and

level information superimposed on your
video screen. Follow the instructions in
steps 1 through 6 above to calibrate the
system, and press the 

button

l

again to cancel the test.

CONGRATULATIONS! You have com-
pleted a basic setup and you are now
ready to enjoy the finest in home theater
and music listening enjoyment.
