Once the menu appears on your video screen,
first use the
Button
to move the on-
screen cursor so that it is next to the TEST
TONE line. Press the / Buttons
so that ON is highlighted.
You will hear a test noise circulate from speaker
to speaker in a clockwise direction around the
room. The test noise will play for two seconds in
each speaker before circulating, and a blinking
on-screen cursor will appear next to the name of
each speaker location when the sound is at that
speaker. Now turn up the volume until you can
hear the noise clearly.
IMPORTANT NOTE: Because this test noise will
have a much lower level than normal music, the
volume must be lowered after the adjustment for
all channels is made, but BEFORE you return to
the main menu and the test tone turns off.
NOTE: Remember to verify that the speakers
have been properly connected. As the test noise
circulates, listen to make certain that the sound
comes from the speaker position shown in the
Main Information Display
. If the sound
comes from a speaker location that does NOT
match the position indicated in the display, turn
the AVR 4550 off using the Main Power
Switch
and check the speaker wiring or
connections to external power amplifiers to make
certain that each speaker is connected to the
correct output terminal.
After checking for speaker placement, let the test
noise circulate again, and listen to see which
channels sound louder than the others. Using the
front left speaker as a reference, press the
Buttons
on the remote to bring all
speakers to the same volume level. When one of
the
buttons is pushed, the test noise circula-
/
tion 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 five seconds. The on-screen cursor and the
test noise can also be moved directly to the
speaker to be adjusted by pressing the
buttons
on the remote.
Continue to adjust the individual channels until

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 34.
When all channels have an equal volume level,
the adjustment is complete. Now turn the
Volume
down to about -40dB, otherwise
the listening level may be too high as soon as
the source's music starts to play. To exit this
menu, press the

When all channels have the same output level,

otherwise the listening level may be too high as

Afterwards press the Test Tone Selector
button again to turn the test tone off and
complete the process.
IMPORTANT NOTE: The Output level adjust-
ment made will be effective for all inputs, but
only for the actual surround mode selected. To be
effective for any other mode select that mode
(with any input) and repeat the level adjustment
described above. This will also allow you to com-
pensate level differences between speakers, that
may be different with each surround mode, or to
increase or decrease the level of certain speakers
intentionally, depending on the surround mode
selected.
Note: Output level adjustment is not available
for the VMAx or Surround Off mode, as no
surround speakers are used (so level differences
between the speakers in the room cannot occur).
But to compensate level differences between
stereo, VMAx and other surround modes (inde-
pendently from the input selected) the outputs
can be adjusted with the Level Trim Adjustment
procedure, see page 34, also for the Surround Off
(Stereo) and VMAx modes.
Once the settings outlined on the previous pages
have been made, the AVR 4550 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 pages 36 to 37 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 in this section.
Note that any settings changed at any time, also
when the discrete buttons are used only, will be
stored in memory in the AVR 4550, also if it´s
turned off completely, unless it will be reset (see
page 48).
Having completed the setup and configuration
process for your AVR 4550, you are about
to experience the finest in music and home-
theater listening. Enjoy!
