Output Level Trim Adjustment
Normal output level adjustment for the AVR 240 is
established using EzSet+, or the internal test tone, as
outlined on pages 29–30. In some cases, however, it
may be desirable to adjust the output levels using pro-
gram material such as a test disc, or a selection you
are familiar with.
To adjust the output levels using program material, first
set the reference volume for the front left and front right
channels using the Volume Control Òb .
If you are using a disc with test signals or an external
signal generator as the source from which to trim the
output levels, you may use a handheld SPL meter to
guide you to the correct SPL levels. Set the meter to
the C-Weighting Slow scale, and adjust the volume
until the meter reads 75dB.
Once the reference level has been set, press the
Channel Select Button
m
and FRONT L
LEVEL
will appear in the Lower Display Line
Q and semi-OSD. To change the level, first press
the
Set Button p, and then use the
⁄
/
¤
Buttons
n
to raise or lower the level. DO NOT
use the volume control, as this will alter the
reference setting.
Once the change has been made, press the
Set
Button
p and then press the
⁄
/
¤
Buttons
n
to select the next output channel location you wish to
adjust. To adjust the subwoofer level, press the
⁄
/
¤
Buttons
n
until WOOFER LEVEL appears in
the
Lower Display Line Q and on screen.
Repeat the procedure as needed until all channels
requiring adjustment have been set. When all adjust-
ments have been made and no further adjustments
are made for five seconds, the AVR 240 will return to
normal operation.
The channel output for any input may also be adjusted
using the full-OSD on-screen menu system. First, set
the volume to a comfortable listening level using the
Volume Control Òb. Then, press the OSD
Button
v to bring up the MASTER MENU
(Figure 1). Press the
¤
Button n until the on-
screen
›
cursor is next to the MANUAL
SETUP
line. Press the Set Button p to display
the
MANUAL SETUP submenu, and use the
⁄/¤ Buttons n to scroll to the CHANNEL
ADJUST
line. Press the Set Button p again to
display the
CHANNEL ADJUST submenu.
Once the menu appears on your video screen, first
use the
⁄
/
¤
Buttons n to move the on-screen
›
cursor so that it is next to the TEST TONE
line. Press the
‹
/
›
Buttons o so that OFF
appears. This will turn off the test tone and allow you
to use your external test disc or other source material
as the reference. Then, use the
⁄
/
¤
Buttons n
until the › cursor is next to the TEST TONE
SEQ
line so that you may select between automatic
and manual movement of the test tone from one
channel to the next. When
AUTO appears, the test
tone will automatically circulate from one channel to
the next, pausing momentarily at each channel. If you
adjust the level of any channel, the test tone will
remain paused at that channel until several seconds
after your last adjustment before continuing to the next
channel. When
MANUAL appears, the test tone will
remain paused at the last channel until you use the
⁄/¤ Buttons n to select another channel.
At each channel position, use the
‹
/
›
Buttons o
to change the output level. Remember, the goal is to
have the output level at each channel be equal when
heard at the listening position.
If you wish to reset all the levels to their original
factory default of 0dB offset, press the
⁄
/
¤
Buttons
n so that the on-screen cursor is next to the
CHANNEL RESET line and press the
‹
/
›
Buttons o so that the word ON appears. After the
levels are reset, resume the procedure outlined above
to reset the levels to the desired settings. When all
adjustments are done, press the
⁄
/
¤
Buttons
n
to move the on-screen
›
cursor so that it is next to
BACK TO MANUAL SETUP and then press
the
Set Button p if you wish to go back to the
manual setup menu to make other adjustments. If you
have no other adjustments to make, press the
OSD
Button
v to exit the menu system.
NOTE: The output levels may be separately trimmed for
each digital and analog surround mode by selecting that
mode and following the instructions shown above.
