Output Level Trim Adjustment
Normal output level adjustment for the
AVR480 is established using the test
tone, as outlined on page 22. In some
cases, however, it may be desirable to
adjust the output levels using program
material such as a test disc, or a selec-
tion you are familiar with. Additionally,
the output level for the subwoofer and
those for the Stereo mode can only be
adjusted using this procedure.
To adjust the output levels using program
material, first select the surround mode
for which you want to trim the speakers
(see NOTE below) by selecting the appro-
priate input, associated with the desired
surround mode, start your program mate-
rial source and set the reference volume
for the front left and front right channels
using the
Volume Control
$
W
.
Once the reference level has been set,
press the
Channel Select Button
B
Ó
and note that FL LEVEL
will appear in the Main Information
Display
K
for five seconds. To change
the level, first press the
Set Button
E
^
, and then use the Selector
Buttons
%
or the

Buttons
C
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
E
^
and then press
the
Selector Buttons
%
or the

to select the next output
channel location that you wish to
adjust (
C LEVEL, FR LEVEL,
SR LEVEL, SL LEVEL
). To adjust
the subwoofer level, press the

until SW LEVEL appears in the Main
Information Display

(only available
if the subwoofer was selected during the
speaker configuration; see page 19).
Press the
Set Button

^
when the
name of the desired channel appears in
the
Main Information Display
K
and
on-screen display, and follow the instruc-
tions shown above to adjust the level.
Repeat the procedure as needed until all
channels requiring adjustment have been
set. When all adjustments have been
made, press the
Set Button
E
^
twice, and the AVR480 will return to
normal operation.
NOTE: The output levels may be sepa-
rately trimmed for each digital and analog
surround mode. If you wish to have differ-
ent trim levels for a specific mode, select
that mode and then follow the instructions
in the steps shown above.
Changing the levels by the trim adjust-
ment as described above will automati-
cally change the level settings shown
during the Output Level Adjustment (see
page 22) correspondingly (and vice versa)
and will remain in the AVR480´s memory
system, even when the unit is turned off.
With Stereo mode the adjustment proce-
dure described above is the only way to
trim the output level.
Display Brightness
The AVR480’s front-panel Main
Information Display
(
is set at a
default brightness level that is sufficient
for viewing in a normally lit room.
However, in some home theater installa-
tions, you may wish to occasionally lower
the brightness of the display, or turn it off
completely.
The display brightness may be changed
by pressing and holding the
Set Button
^
on the front panel for three seconds
until the message in the
Main Informa-
tion Display
K
reads VFD FULL.
Within five seconds, press the front-
panel

until the desired
brightness display level is shown. At that
point, press the
Set Button
^
again to
enter the setting.
Memory Backup
This product is equipped with a memory
backup system that preserves tuner
presets and system configuration
information if the unit is turned off
completely, accidentally unplugged or
subjected to a power outage. This
memory will last for approximately two
weeks, after which time all information
must be reentered.
