4. Press the

the Selector buttons
&
on the front panel
until either F-LARGE or F-SMALL
appears, matching the type of speakers you have
at the left-front and right-front positions, as
described by the definitions shown in preceding
section.
When SMALL is selected, low frequency front
channel sounds will be sent only to the subwoofer
output. Note that if you choose this option and
there is no subwoofer connected, you will not
hear any low frequency sounds from the front
channels. This setting is not available with stereo
mode to ensure purest sound by bypassing the
crossovers of the DSP´s.
When LARGE is selected, a full-range output
will be sent to the front left and front right out-
puts. Depending on the subwoofer configuration
(see below), the front left and right bass informa-
tion may also be directed to a subwoofer.
Important Note: When a speaker set with two
front satellites and a passive subwoofer is used,
connected to the front speaker outputs
,
the fronts must be set for LARGE.
5.When you have completed your selection for
the front channels, press the Enter button
E
on the remote control, or the Set button on the
front
Ó
, and then press the

control, or the Set button on the front
Ó
again, and use the
⁄
/
¤
buttons
C
on the
remote, or the Selector buttons
&
on the
front panel, to select the option that best
describes your system based on the Center
speaker definitions shown in preceding section.
When SMALL is selected, low frequency cen-
ter channel sounds will be sent to the Fronts, if
they are set for LARGE and Sub is turned off.
When Sub is on, low frequency center channel
sounds will be sent to the subwoofer only.
When LARGE is selected, a full-range output
will be sent to the center speaker output, and
with analog and digital surround modes (except
with the Pro Logic II Music mode) NO center
channel signal will be sent to the subwoofer out-
put.
When NONE is selected, no signal will be sent
to the center channel output. The receiver will
operate in a “phantom” center channel mode
and center channel information will be sent to
the left and right front channel outputs and its
bass will be sent to the subwoofer output too as
long as SUB L/R+LFE is selected in the SUB-
WOOFER line in this menu (see below). This
mode is needed if no Center speaker is used.
7. When you have completed your selection for
the center channel, press the Enter button
E
on the remote control, or the Set button on the
front
Ó
, and then press the

control, or the Set button on the front
Ó
again, and then use the
⁄
/
¤
buttons
C
on the
remote or the Selector buttons
&
on the front
panel to select the option that best describes
your system based on the Surround speaker
definitions shown in preceding section.
When SMALL is selected, with all digital sur-
round modes low frequency surround channel
sounds will be sent to the Fronts, when Sub is
turned off, or to the subwoofer output when Sub
is on. With the analog surround modes the rear
bass feed depends on the mode selected and
the setting of the sub and front speakers.
When LARGE is selected, a full-range output
will be sent to the surround channel outputs
(with all analog and digital surround modes),
and, except with Hall and Theater modes, NO
surround channel bass will be sent to the sub-
woofer output.
When NONE is selected, surround sound
information will be split between the front-left
and front-right outputs. Note that for optimal
performance when no surround speakers are in
use, the Dolby 3 Stereo mode should be used
instead of Dolby Pro Logic.
9. When you have completed your selection for
the surround channel, press the Enter button
E
on the remote control, or the Set button on
the front
Ó
, and then press the
⁄

buttons
C
on the remote or the Selector buttons

control, or the Set button on the front
Ó
, and
then press the
⁄
/
¤
buttons
C
on the remote
or the Selector buttons
&
on the front panel
to select the option that best describes your
Subwoofer system.
The choices available for the subwoofer position
will depend on the settings for the other speak-
ers, particularly the front left/right positions.
If the front left/right speakers are set to
SMALL, the subwoofer will automatically be
set to SUB, which is the “on” position.
If the front left/right speakers are set to
LARGE, three options are available:
• If no subwoofer is connected to the AVR 1550,
press the arrow buttons
C
&
so that
NONE appears in the display. When this
option is selected, all bass information will be
routed to the front left/right “main” speakers.
• If a subwoofer is connected to the AVR 1550,
you have the option to have the front left/right
“main” speakers reproduce bass frequencies at
all times, and have the subwoofer operate only
when the AVR 1550 is being used with a digital
source that contains a dedicated Low Frequency
Effects, or LFE soundtrack.This allows you to use
both your main and subwoofer speakers to take
advantage of the special bass created for certain
movies. To select that option press the arrow
buttons
C
&
so that SUB(LFE) appears
in the display.
• If a subwoofer is connected and you wish to
use it for bass reproduction in conjunction with
the main front left/right speakers, regardless of
the type of program source or surround mode
you are listening to, press the arrow buttons
C
&
so that L/R+LFE appears in the
display. When this option is selected, a “com-
plete” feed will be sent to the front left/right
“main” speakers, and the subwoofer will receive
the front left and right bass frequencies under
the crossover frequency 80 Hz, additionally to
the LFE soundtrack (see above).
11. When all speaker selections have been made
for the input selected, Press the Enter button
E
on the remote control, or the Set button on
the front
Ó
twice or simply wait for three
seconds until the display returns to the normal
mode.
