Operation
Basic Operation
Once you have completed the setup and configu-
ration of the AVR 2550, 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 2550 On or Off
• When using the AVR 2550 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 orange
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
456
.
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.
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
on the remote. Power will be shut
off to any equipment plugged into the rear panel
Switched AC Outlets
E
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 2550 for automatic turn-
off, press the Sleep Button
8
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 Preset
Number/Sleep Timer Indicator
Q
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
8
until the
information display returns to normal brightness
and the Sleep indicator numbers return to "0" in
the Main Information Display
M
.
Source Selection
• To select a source, press any of the
Source Selector buttons on the remote
456
.
NOTE: After pressing one of the Input Selector
buttons
4
you must 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 2550 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.
• As the input source is changed, the new input
name will appear in the Main Information
Display
M
and a green LED will light next to
the selected input’s name in the front-panel
Input Indicators
Ô
.
• When a pure audio source (Tuner, CD, Tape) is
selected, the last video input used remains rout-
ed to the Video 1 Outputs
I
and Video
Monitor Output
B
. This permits simultaneous
viewing and listening to different sources.
• When a Video source is selected, its audio sig-
nal will be fed to the speakers and the video sig-
nal for that input will be routed to the appropriate
Monitor Output jack
B
and will be viewable on
a TV monitor connected to the AVR 2550.
Controls and Use of Headphones
• Adjust the volume to a comfortable level using
the front panel Volume Control
(
or remote
Volume Up/Down
buttons.
• The Balance Control
&
may be used to
adjust the relative sound output between the left
front and right front speakers.
• To temporarily silence all speaker outputs
press the Mute button
. This will interrupt
the output to all speakers and the headphone
jack, but it will not affect any recording or dub-
bing that may be in progress. Press the Mute
button
again to return to normal operation.
• During a listening session you may wish to
adjust the Bass Control
^
and Treble
Control
*
to suit your listening tastes or room
acoustics.
• To set the output of the AVR 2550 so that the
output is “flat,” with the Tone controls and the
Balance control de-activated, press the Tone
Mode button
6
button once or twice so that
the words Tone Out appear momentarily
in the Main Information Display
M
.To
return the tone controls to an active condition,
press the Tone Mode
6
button once or twice
so that the words Tone In momentarily
appear in the Main Information Display
M
.
• For private listening, plug the 6.3 mm stereo
phone plug from a pair of stereo headphones
into the front panel Headphone Jack
4
. Note
that when the headphone’s plug is connected,
the word HEADPHONE will scroll once
across the Main Information Display
M
and
all speakers will be silenced. When the head-
phone plug is removed, the audio feed to the
speakers will be restored.
