speaker position shown in the Main
Information Display
K
. If the sound
from a speaker location does NOT match
the position indicated in the display, turn
the AVR480 off using the
Main Power
Switch
1 and check the speaker wiring
to make certain that each speaker is con-
nected to the correct output terminal.
After checking for speaker placement, let
the test tone circulate again, and listen to
see which channels sound louder than
the others. Using the front left speaker as
a reference, press the
/
¤
Buttons
C
on the remote to bring all speakers
to the same volume level. Note that when
one of the
/
¤
Buttons
C
is pushed,
the test tone circulation will pause on the
channel being adjusted to give you time
to make the adjustment. When you
release the button, the circulation will
resume after 5 seconds.
Continue to adjust the individual speak-
ers until they all have the same volume.
Adjustments should be made with the
/

Buttons
C
only, NOT the main
volume controls.
NOTE: The subwoofer output level is not
adjustable using the test tone. To change
the subwoofer level, follow the steps for
Output Level Trim Adjustment on page 30.
When all channels have the same output
level, turn the
Volume
$
W
down to
about – 40dB; otherwise, the listening
level may be too high as soon as the
source’s music starts to play. Afterwards,
press the
Test Tone Button
7
again to turn the test tone off and com-
plete the process.
IMPORTANT NOTE: The output level
adjustment made will be effective for
the surround mode currently selected,
independent of which source input is
selected. To adjust the output level with
other surround modes, step through all
inputs you’re using by repeatedly press-
ing the
Source Selector Buttons
!
on
the front panel or the appropriate
Input
Selectors
5
on the remote. When the
indicator for any surround mode for which
the level adjustment has not yet been
made lights in the
Main Information
Display
K
, repeat the level adjustment
described above. Alternatively, change
the surround mode either by pressing the
Surround Mode Selector Button 7
on the front panel repeatedly, or by press-
ing the
Surround Mode Selector j
on the remote and the
/
¤
Buttons
C
until the desired surround mode
appears in the Main Information
Display
K
. This will also allow you
to compensate for level differences
between speakers, which may be differ-
ent with each surround mode, or to
increase or decrease the level of certain
speakers intentionally, depending on the
surround mode selected.
Once the settings outlined on the previ-
ous pages have been made, the AVR480
is ready for operation. While there are
some additional settings to be made,
these are best done after you have had
an opportunity to listen to a variety of
sources and different kinds of program
material. These advanced settings are
described on page 30 of this manual. In
addition, any of the settings made in the
initial configuration of the unit may be
changed at any time. As you add new or
different sources or speakers, or if you
wish to change a setting to better reflect
your listening taste, simply follow the
instructions for changing the settings for
that parameter, as shown above. Note
that any settings changed at any time
will be stored in memory in the AVR480.
The settings will either depend on the
input (speaker configuration, analog/
digital input selection, surround mode) or
on the surround mode selected (speaker
output level), as described on previous
pages.
Having completed the setup and configu-
ration process for your AVR480, you are
about to experience the finest in music
and home theater listening. Enjoy!
