Advanced Features
The AVR 4550 is equipped with a number of
advanced features that add extra flexibility to
the unit's operation. While it is not necessary to
use these features to operate the unit, they pro-
vide additional options that you may wish to
use.
Surround Amplifier Channel Assignment
The AVR 4550 is equipped with seven full-power
amplifier channels to allow for complete 7.1-
channel operation without the need for
additional external amplifiers. However, in some
installations you may wish to use the traditional
5.1-channel configuration for the main listening
room, which allows the surround back left/right
amplifier channels to be used to power speakers
placed in a remote zone location.
If you wish to use the Surround Back channel
amplifiers to power the remote zone, you must
change a setting in the
menu. To make that change, first call
up the menu system by pressing the OSD
Button
to bring the
(Figure 1) to the screen. Next, press the
Button
until the cursor is next to the
line. Press the Set Button
to enter the
(Figure 11).

Remember that once this setting is made you
will not be able to take advantage of any of the
6.1/7.1- channel decoding or processing modes,
and no Surround Back speakers must be
selected in the speaker setup procedure outlined
earlier. In addition the speakers used for the
remote zone must be connected to the
Surround Back/Multiroom Speaker
Outputs
. The volume for these speakers is
set by the multiroom system, as explained on
page 38 of this manual.
Once this setting is made, you may press the
Button
to make any of the other
adjustments available on this menu. If no other
adjustments are needed, press the OSD Button
to exit the menu system.

Display Brightness
The AVR 4550'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.
To change the display brightness setting for a
specific listening session, you will need to make
an adjustment in the
menu. To start the adjustment, press the OSD
button
to bring the

Turn On Volume Level
As is the case with most audio/video receivers,
when the AVR 4550 is turned on, it will always
return to the volume setting in effect when the
unit was turned off. However, you may prefer to
always have the AVR 4550 turn on at a specific
setting, regardless of what was last in use when
the unit was turned off. To change the default
condition so that the same volume level is
always used at turn-on, you will need to make
an adjustment in the
menu. To start the adjustment, press the OSD
button

be made with the regular volume controls.
NOTE: Since the setting for the turn-on volume
cannot be heard while the setting is being made,
you may wish to determine the setting before
making the adjustment. To do this, listen to any
source and adjust the volume to the desired
level using the regular volume controls
When the desired volume level to be used at
turn-on is reached, make a note of the setting as
it appears in the lower third of the video screen
or in the Main Information Display
A typical volume level will appear as a negative
number such as -25dB. When making the
