When there are no speakers available at a specific
position, select
NONE
. When this option is chosen
for the Center or Side Surround speakers, the sound
that would normally be sent to these channels will be
split between the front left and right speakers. Note
that when your system does not include Center or
Surround speakers, the use of Dolby Virtual Speaker
as a surround mode may provide a sound field that
simulates the presence of these speakers. (See the
appendix for more information on the Dolby Virtual
Speaker mode.)
Note that when
NONE
is selected for the Back
Surround speakers, the 6.1/7.1 channel surround
modes are not available. When this is the case for
your system, you may wish to take advantage of the
availability of the unused amplifier channel pair to
power a second set of speakers in another room.
(See page 44 for more information on amplifier
configuration.)

LFE Low-Pass-Filter Setting
The
LFE LP FLT
line selects the frequency set-
ting below which sounds that may be available from a
special low-frequency effects (LFE) track are sent to
the subwoofer. In most cases, this setting will be set
accurately by EzSet/EQ but, should you wish to make
a change from that setting or the 120Hz frequency
that is most commonly used in the creation of LFE
channels by motion picture sound mixers, after making
sure that the

Sub Mode Setting
When the Front Left/Right speakers are configured
as “Large” and a subwoofer is detected by EzSet/EQ
or manually configured as being available, additional
options are available to further customize bass redirec-
tion. To change these settings, first make sure that
the

EzSet/EQ after all changes have been made.
The following options are available:
• The default setting for Large front left/right speakers
when a subwoofer is present is
SUB L/R +
LFE
. In this mode, all sounds below the crossover
point set on the
LFE LP FLT
line will be sent
to BOTH the subwoofer and the front left/right
speakers.
• To send only the LFE channel information to the
subwoofer, but have all other (“derived”) low-
frequency sounds sent to the front left/right
speakers, select the
SUB (LFE)
setting.
• To have low-frequency information sent to the sub-
woofer only when Large speakers are selected,
choose
SUB (L/R)
. This option is only avail-
able when the unit is set to
SURROUND OFF
so that a pure analog audio path is provided.
• When no subwoofer is present and Large speakers
are configured for the front left/right position, select
NONE
. This will route all low-frequency information
to the front left/right speakers.
When the
SPEAKER SIZE
menu returns to
the screen, replacing the warning message, press the

Subwoofer Size
The final setting on the
SPEAKER SIZE
menu
enables you to change the setting for the subwoofer
size. In the event that EzSet/EQ did not accurately
enter the correct size, or if you wish to experiment
with a different setting, first make sure that the

the screen; then press the

Select a setting that best matches the diameter of
your subwoofer’s driver, or which provides the appro-
priate high-pass filter setting for your system. In each
case, the frequency of the high-pass filter determines
the frequencies below which no information is sent to
the subwoofer:
• The setting for an 8-inch/200mm driver activates
a 38Hz subwoofer high-pass filter.
• The setting for a 10-inch/250mm driver activates
a 30Hz subwoofer high-pass filter.
• The setting for a 12-inch/305mm driver activates
a 20Hz subwoofer high-pass filter.
• The setting for a 15-inch/380mm driver activates
a 15Hz subwoofer high-pass filter.

made to the settings on this menu, following the
instructions for using the Manual mode shown on
page 26.
Delay Settings
Due to the different distances between the listening
position and each speaker position, the amount of
time it takes for sound to reach your ears from each
channel is different. You may compensate for this dif-
ference through the use of the delay settings to adjust
the timing for the speaker placement and acoustic
conditions in your listening room or home theater.
In most cases, the settings established by EzSet/EQ
are accurate to under a foot, but the placement of
the microphone and other factors may influence
the setting. Should you wish to manually adjust the
channel delay times, follow the instructions shown
below. Whenever adjustments to the delay settings are
made remember that the distance settings need not
be accurate to the inch, as the system is designed to
accommodate a typical listening area rather han the
precise measurement from the speakers to a specific
“sweet spot” position.
In addition to providing delaying adjustments for each
individual speaker position, the AVR 445 allows you to
adjust the delay for the combined output of all speak-
ers as a group. This feature is called A/V Sync Delay;
it allows you to compensate for delays to the video
image that may be caused by the processing in prod-
ucts such as digital video displays, video scalers, digital
cable or satellite systems, or digital video recorders.
With proper adjustment of the setting for A/V Sync
Delay, you can eliminate the loss of lip sync that may
be introduced when video signals are digitized.
