Semi-OSD Settings
The semi-OSD system places one line messages
at the lower third of the video display screen
whenever the Volume, Input Source, Surround
mode or tuner frequency of any of the configura-
tion settings are changed.The semi-OSD system
is helpful in that enables you to have feedback
on any control changes or remote commands
using the video display when it is difficult to
view the front-panel displays. However, you may
occasionally prefer to turn these displays off for
a particular listening session.You may also want
to adjust the length of time the displays remain
on the screen. Both of those options are possible
with the AVR 5550.
To turn off the semi-OSD system, you will need
to make an adjustment in the ADVANCED
SELECTmenu (Figure 11). To start the
adjustment, press the OSD button
L
to bring
the
MASTERMENU to the screen. Press the
⁄
Button
D
, until the on-screen › cursor is
next to the ADVANCED line. Press the Set
Button
F
to enter the ADVANCED
SELECTmenu.
At the ADVANCEDSELECT menu
make certain that the on-screen
› cursor is next
to the SEMIOSDline by pressing the

buttons
D
as needed. Next, press the
›
button
a
so that the word OFFis highlighted in
the video display.
Note that this setting is temporary and will
remain active only until it is changed or until the
AVR 5550 is turned off. Once the unit is turned
off, the semi-OSD displays will remain activated,
even if they were switched off for the previous
listening session.
To change the length of time that the semi-OSD
displays remain on the screen, go to the
ADVANCEDSELECT Menu as out-
lined earlier, and press the

buttons
D
as
needed, until the on-screen
›
cursor is next to
the SEMI-OSD TIMEOUTline. Next,
press the

Buttons
Ea
until the desired
time in seconds is displayed. Note that unlike
most of the other options in this menu, this is a
permanent setting change, and the time-out
entry will remain in effect until it is changed,
even when the unit is turned off.
If you wish to make other adjustments in the
menu, press the

Buttons
D
until the on-
screen

cursor is next to the desired setting or
the BACKTOMASTER MENUline
and press the Set button

. If you have no
other adjustments to make, press the OSD
Button

to exit the menu system.
Full-OSD Time Out Adjustment
The FULL OSDmenu system is used to
simplify the setup and adjustment of the
AVR 5550 using a series of on-screen menus.
The factory default setting for these menus
leaves them on the screen for 20 seconds after a
period of inactivity before they disappear from
the screen or Time Out. This Time Out is a safety
measure to prevent the menu text from burning
into the CRTs in your monitor or projector, which
might happen if they were left on indefinitely.
However, some viewers may prefer a slightly
longer or shorter period before the Time Out
display.
To change the Full-OSD Time Out, you will need
to make an adjustment in the ADVANCED
SELECTmenu (Figure 11). To start the
adjustment, press the OSD button
L
to bring
the
MASTERMENU to the screen. Press the
⁄
button
D
, until the on-screen ¤ cursor is
next to the ADVANCED line. Press the Set
Button

to enter the ADVANCED
SELECTmenu (Figure 11).
At the ADVANCEDSELECT menu

Multiroom Operation
The AVR 5550 is fully equipped to operate as the
control center for a complete multiroom system
that is capable of sending one source to a sec-
ond zone in the house while separate source is
listened to in the main room. In addition to pro-
viding for control over the selection of the
remote source and its volume, the AVR 5550
offers a comprehensive range of options for
powering the speakers in the second zone.
• Using the line-level Multiroom Audio
Outputs
7
, the selected source may be fed to
optional, external power amplifiers that may be
matched to the specifics of the installation.
• When the main room system is configured for
5.1 operation, the Surround Back Left/Right
amplifier channels may be used to power the
remote zone so that no additional amplifiers are
required.
• Using built-in A-BUS Ready technology,
optional A-BUS modules may be connected to
the AVR 5550 via a single Category Five wire, so
that remote zone speakers may be powered
directly from the module or keypad without the
need for additional power, IR sensor or volume
control wires to be run to the second zone.
In addition, the AVR 5550 includes a remote IR
sensor input so that remote control commands
from the Zone II remote included with the unit
may be transmitted to the unit, while standard
IR input/output jacks allow the remote zone’s
commands to be sent to compatible IR-con-
trolled source devices.
Installation
Although simple remote room systems may be
installed by the average do-it-yourself hobbyist,
the complexity of your multizone/multiroom sys-
tem involves running wires inside of walls where
the services of a specially trained installer may
be required. Regardless of who does the work,
please remember that local building codes may
govern in-wall electrical work, including proper
specification of any wiring used and the way in
which it is connected.You are responsible for
making certain that all Multiroom installation
work is done properly and in compliance with all
applicable codes and regulations.
For standard installations, follow the instructions
shown on page 16 for the connection of speaker
wire and IR remote wiring to the AVR 5550.
For installations where the Surround Back
Left/Right amplifier channels are used to power
the remote zone, make certain that the system is
configured for that type of operation, as shown
on page 37.
For installations where A-BUS modules are used,
follow the instructions provided with the A-BUS
remote modules or keypads.
