Output Level Trim Adjustment

Normal output level adjustment for the AVR 140 is
established using the test tone, as outlined on pages
23–24. In some cases, however, it may be desirable
to adjust the output levels using program material such
as a test disc, or a selection you are familiar with.
Additionally, the output level for the subwoofer can
only be adjusted using this procedure.
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 Ò
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
/
⁄ ¤
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 140 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

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
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. Regardless of the
method used to adjust the output levels, whether the
test tone or an external source is used, remember that
when the AVR is configured for 6.1 operation with only
a single surround back speaker, you will still have an
output adjustment for both a surround back left and

there is only one speaker. This is not a duplicate
adjustment. Rather, it is needed so that the proper bal-
