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 4550.
To turn off the semi-OSD system, you will need
to make an adjustment in the
ADVANCED
SELECT
menu (Figure 11). To start the
adjustment, press the
OSD
button
L
to bring
the
MASTER MENU
to the screen. Press the
⁄
Button
D
, until the on-screen
›
cursor is
next to the
A D V A N CE D
line. Press the
Set
Button
F
to enter the
ADVANCED
SELECT
menu.
At the
ADVANCED SELECT
menu make
certain that the on-screen
›
cursor is next to the
S E M I O S D
line by pressing the

but-
tons
D
as needed. Next, press the
›
button
&
so that the word
O F F
is highlighted in the
video display.
Note that this setting is temporary and will
remain active only until it is changed or until the
AVR 4550 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
ADVANCED SELECT
Menu as outlined
earlier, and press the
⁄

buttons
D
as need-
ed, until the on-screen
›
cursor is next to the
SEMI-OSD TIME OUT
line. Next, press
the
‹

Buttons
E&
until the desired time
in seconds is displayed. Note that unlike most of
the other options in this menu, this is a perma-
nent 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

until the on-

the

adjustments to make, press the
OSD
Button

to exit the menu system.
Full-OSD Time Out Adjustment
The
FULL OSD
menu system is used to
simplify the setup and adjustment of the
AVR 4550 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
SELECT
menu (Figure 11). To start the
adjustment, press the
OSD
button
L
to bring
the
MASTER MENU
to the screen. Press the

next to the

Multiroom Operation
The AVR 4550 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 4550
offers a comprehensive range of options for
powering the speakers in the second zone.
• Using the line-level
Multiroom Audio
Outputs
, 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, option-
al A-BUS modules may be connected to the AVR
4550 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 4550 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 com-
mands to be sent to compatible IR-controlled
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 18 for the connection of speaker
wire and IR remote wiring to the AVR 4550.
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 36.
For installations where A-BUS modules are used,
follow the instructions provided with the A-BUS
remote modules or keypads.
