SYSTEM CONFIGURATION
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
SPEAKER SIZE menu (Figure 19) is on
the screen, and then press the
⁄/¤ Navigation
Button

so that the cursor is pointing to
SUB MODE. Press the ‹/› Navigation Button
n
©
to begin the selection process, and note that
the warning message (Figure 20) will appear reminding
you to rerun 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
‹/› Navigation Button n
©
to make your
selection. When the desired setting appears, press the
⁄/¤ Navigation Button n
©
to move the
cursor to any other line on this menu where you wish
to make a setting change, or go to the
BACK TO
MANUAL SETUP
menu and then press the
Set Button p
œ
to continue with overall
configuration.
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
SPEAKER SIZE menu (Figure 19) is on
the screen; then press the
⁄/¤ Navigation Button
n
©
so that the cursor is pointing to SUB
SIZE
and then press the ‹/› Navigation
Button
n
©
to begin the selection process. Note
that a warning message (Figure 20) will appear for 4
seconds to remind you to rerun EzSet/EQ after all
changes have been made.
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.
When all changes to speaker-related settings have
been made, press the

until the cursor is on the BACK TO

menu; then press the Set
Button
p

so that you may make any other
adjustments to the system parameters. Remember to
rerun the EzSet/EQ system if any changes have been
made to the settings on this menu, following the
instructions for using the Manual mode shown on
page 28.
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 645 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 personal video recorders.
With proper adjustment of the setting for A/V Sync
Delay, you can eliminate the loss of lip sync that may
be caused by digital video applications.
To make any changes to the delay settings, go to the
DELAY ADJUST submenu within the MANUAL
SETUP
menu (Figure 18). To do this, first press
the
OSD Button
∫
so that the MASTER
MENU
(Figure 1) appears. Next, press the
