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 

button 

1

until it is flush with the

front panel. Note that the 

3

will turn orange.

2. Install the supplied AAA batteries in the

remote control, as shown on page 15.

3. Press the 

2

on the front panel or the 

button 

c

on the remote

and note that the 

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 

button 

Ò

. Press and hold the

Ó

until 

the word 

CENTER

appears in the

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

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 

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 

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 

button 

4

to

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

NOTES:

•

In order to enter the speaker configura-
tion, the 

7

must be

in the “in” position.

•

In order to enter information for the
center speaker, the AVR55 must be in
the Dolby Pro Logic or Dolby 3 Stereo
mode. To select either of these modes,
press the front panel 

Ò

or one of the

buttons 

`

on the remote.
