System Configuration
AVR55 120 volt
System Configuration
Once the speakers have been placed
in their proper positions and connected
to the AVR55, the final steps in the instal-
lation process involve configuration of
the unit for the specific speaker types
in use and the balancing of speaker
output levels.
Before proceeding, check to make
certain that all connections are secure
and follow these steps:
1. Plug the unit into an unswitched AC
outlet and press the
Main Power
button
1
until it is flush with the
front panel. Note that the
Power
Indicator
3
will turn orange.
2. Install the supplied AAA batteries in the
remote control, as shown on page 15.
3. Press the
System Power Control
2
on the front panel or the
Main
Power On
button
c
on the remote
and note that the
Power Indicator
3
will turn green.
Bass Management
The settings made during the speaker
configuration process will determine
which speakers receive low-frequency
information, which are those sounds
below 100Hz. If a subwoofer is installed,
it will receive low-frequency information,
and none will be sent to the front
left/right speakers. If you do NOT have
full-range front speakers, it is important
that “NO” be selected as the subwoofer
setting option to prevent damage to your
front speakers.
Speaker Configuration
The next few steps tell the AVR55 which
type of speakers are installed. This, in
turn, configures the bass management
system so that low-frequency sounds are
directed to the proper speaker location.
1. Press the front panel
Surround
Mode
button
Ò
. Press and hold the
Speaker Mode Selector
Ó
until
the word
CENTER
appears in the
Information Display
F . The word
LARGE
,
SMALL
or
NONE
will also
appear, and blink to indicate the current
setting. Release the button for a second,
and while the word
LARGE
is still
blinking in the display, press the
Speaker Mode Selector
Ó
again
until the word describing the type of
center speaker installed in your system
appears.
•
Select
LARGE
if your center channel
speaker is a traditional full-range
speaker that is capable of reproducing
frequencies below 100Hz.
•
Select
SMALL
if your center
channel speaker is a smaller “satellite”
type speaker that is not capable of
extended bass response or reproducing
frequencies below 100Hz.
•
Select
NONE
if no center channel
speaker is installed.
2. Once you have made your selection,
immediately press the
Memo
button
4
while the display is still blinking. Note
that the speaker selection will change to
SUBWOOFER
. The word
Yes
or
NO
will blink indicating the current setting.
Press the
Speaker Mode Selector
Ó
again until the appropriate selection is
made.
•
Select
YES
if a subwoofer is installed.
When
YES
is selected all low-
frequency information will be sent
to the subwoofer, and all front and
surround speakers will only receive
audio information above 100Hz.
•
Select
NO
if no subwoofer is present.
When
NO
is selected the front left/right
and surround speakers will receive a
full-range signal, and the feed to the
center speaker will be based on the
selection mode in the previous step.
3. While your choice is blinking in the
display, press the
Memo
button

to
enter the selection. The display will stop
blinking to indicate that the setting is
entered and then return to normal.
