Basic Operation
Once you have completed the setup and configu-
ration of the AVR 4550, it is simple to operate
and enjoy. The following instructions should be
followed for you to maximize your enjoyment of
your new receiver:
Turning the AVR 4550 On or Off
• When using the AVR 4550 for the first time, you
must press the
Main Power Switch
1
on the
front panel to turn the unit on. This places the unit
in a Standby mode, as indicated by the amber color
of the
Power Indicator
3
. Once the unit is in
Standby, you may begin a listening session by
pressing the
System Power Control
2
or the
Source
button
%
on the front panel or the
AVR
Selector
5
∫
. Note that the
Power
Indicator
3
will turn green. This will turn the
unit on and return it to the input source that was
last used. The unit may also be turned on from
Standby by pressing any of the
Source Selector
buttons on the remote
4567
∫
ç∂
or the
Source
button
%
on the front
panel.
NOTE:
After pressing one of the
Input Selector
buttons
4
∂
(except VID4) to turn the unit on,
press the
AVR Selector
5
∫
to have the
remote control the AVR functions.
To turn the unit off at the end of a listening ses-
sion, simply press the
System Power Control
2
on the front panel or the
Power Off Button
3
å
on the remote. Power will be shut off to
any equipment plugged into the rear panel
Switched AC Outlets
and the
Power
Indicator
3
will turn orange.
When the remote is used to turn the unit “off” it
is actually placing the system in a Standby mode,
as indicated by the orange color of the
Power
Indicator
3
.
When you will be away from home for an
extended period of time it is always a good idea
to completely turn the unit off with the front
panel
Main Power Switch
1
.
NOTE:
All preset memories may be lost if the
unit is left turned off with the
Main Power
Switch
1
for more than two weeks.
Using the Sleep Timer
• To program the AVR 4550 for automatic turn-
off, press the
Sleep Button
9
on the remote.
Each press of the button will increase the time
before shut down in the following sequence:
The sleep time will be displayed in the
Lower
Display Line
B
and it will count down until
the time has elapsed.
When the programmed sleep time has elapsed,
the unit will automatically turn off (to Standby
mode). Note that the front panel display will dim
to one half brightness when the Sleep function is
programmed. To cancel the Sleep function, press
and hold the
Sleep Button
9
until the infor-
mation display returns to normal brightness and
the Sleep indicator numbers disappear and the
words
S L E E P O F F
appear in the
Main
Information Display
˜
.
Source Selection
• To select a source, press any of the
Source
Selector
buttons on the remote
46
ç∂
.
NOTE:
After pressing one of the
Input Selector
buttons
4
∂
to turn the unit on, press the
AVR Selector
5
∫
to have the remote
control the AVR functions.
• The input source may also be changed by
pressing the front-panel
Input Source Selector
button
%
. Each press of the button will move
the input selection through the list of available
inputs.
• As the input is changed, the AVR 4550 will
automatically switch to the digital input (if
selected), surround mode and speaker configura-
tion that were entered during the configuration
process for that source.
• The front-panel
Video 4 Inputs
Ô
,
Optical
Digital 3 Input
*
or the
Coaxial Digital 3
Input
Ó
may be used to connect a device such
as a video game or camcorder to your home
entertainment system on a temporary basis.
• As the input source is changed, the new input
name will appear momentarily as an on-screen
display in the lower third of the video display.
The input name will also appear in the
Main
Information Display
˜
and a green LED will
light next to the selected input’s name in the
front-panel
Input Indicators
ˆ
.
• When a pure audio input (CD, Tuner, Tape,
6/8 Channel Input) is selected, the last video
input used remains routed to the
Video Out-
puts
(except from its own Video 1/2
source) and
Video Monitor Output
. This
permits simultaneous viewing and listening to
different sources.
• When a Video source is selected, its audio
signal will be fed to the speakers and the video
signal for that input will be routed to the appro-
priate
Monitor Output Jack
and will be view-
able on a TV monitor connected to the AVR 4550.
If a component video source is connected to the
DVD
or
Video 2
Component Inputs
, it
will be routed to the
Component Video
Outputs
. Make certain that your TV is set to
the proper input to view the appropriate video
signal (composite, S-Video or component video,
see Notes for S-Video on page 16).
6-Channel/8-Channel Direct Input
• There are two input choices available for use
with sources such as a DVD-Audio or SACD play-
er that are connected to the
8-Channel Direct
Inputs
'
. Select the appropriate input accord-
ing to the way your system and source equip-
ment is configured:
• The
6 C H DIRECT
input should be used
when the SBR and SBL inputs are NOT in use and
the input source device has its own internal bass
management system. This input passes the input
from the source directly through to the volume
control without any analog to digital conversion
and it mutes the unused input jacks to prevent
unwanted noise from interfering with system per-
formance.
• The
8 C H DIRECT INPUT
should be
used when an input is connected to all eight
8-Channel Direct Inputs
'
and when the
input source device has its own internal bass
management system. This input passes the input
from the source directly through to the volume
control without any analog to digital conversion
and it mutes the unused input jacks to prevent
unwanted noise from interfering with system
performance.
Note that when the 6-Channel or 8-Channel
Direct Input is in use, you may not select a sur-
round mode, as the external decoder determines
the processing in use. In addition, there is no
signal at the record outputs or bass management
when the 6-Channel or 8-Channel Direct Input is
in use and the tone or balance controls will not
function.
