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 amber.
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 “YES” 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 until DOLBY PRO
LOGIC
appears as the Surround mode.
2. 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 current choice 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 capable of reproducing
frequencies below 100Hz.
• Select SMALL if your center channel
speaker is a smaller “satellite” type
speaker not capable of extended bass
response or reproducing frequencies
below 100Hz.
• Select NONE if no center channel
speaker is installed.
3. 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.
4. 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 sub-
woofer, and the front, center 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.
5. While your choice is blinking in the
display, press the Memo 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
Speaker Switch 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
Surround
Mode Selector Ò or one of the
Dolby Surround Mode buttons `
on the remote.
