SYSTEM CONFIGURATION SYSTEM CONFIGURATION
In addition to providing delaying adjustments for each
individual speaker position, the AVR 745 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 view or change the current delay settings, make
sure the EZSET/EQ MAIN menu (Figure 12)
is on the screen. Press the / Navigation
⁄ ¤
Buttons D© to move the cursor to DELAY
ADJUST and then press the OK/Enter Button
E on the TC 30 or the Set Button œ on the
ZR 10. The DELAY ADJUST menu (Figure
29) will appear on the screen.

Once the DELAY ADJUST menu is on your
screen, note that the default for distance settings is in
feet. If your measurements are in feet, proceed to the
next step; if your measurements are made in meters,

Then, press the ‹ / ›
so that METER is highlighted. When the change
in measurement units is made, press the
Navigation Buttons D© to return the cursor
to the FL position.
If you wish to reset all delay settings to the factory
defaults, as shown in Figure 29, press the
Navigation Buttons D© until the cursor is point-
ing to the DELAY RESET line. Next, press the
Navigation Buttons D© so that ON is

highlighted in reverse video. The settings will reset, and
you may now continue to make any needed changes
following the instructions below. Once you make the
first change to the default settings, the DELAY
RESET line will return to OFF, indicating that
the factory defaults are no longer in effect.
To change a setting, first make certain that the on-
screen cursor is pointing to FL, and press the
Navigation Buttons D© until the distance from
the center speaker to the preferred listening position is

entered. Next, press the / Navigation Buttons

tions that have been set to LARGE or SMALL
in the SPEAKER SIZE menu, as shown on
page 34, may be adjusted. The appearance of three
dashes next to a speaker position in place of a dis-
tance setting indicates that you have not configured
an active speaker for that location.
If you have already run EzSet/EQII, return to the set-
tings established by the automated system by pressing
Navigation Buttons D© until the
the /

cursor is pointing to the EZSET SETTINGS
line. Next, press the
D© so that ON is highlighted in reverse video.
The settings will be resent to the values calculated
by EzSet/EQII, and the menu will be locked so that
the settings may not be changed. To go back into
the menu and make any manual changes to one or
more channels, you must first return the cursor to the
EZSET SETTINGS line and press the
Navigation Buttons D© so that OFF is high-
lighted in reverse video. This will unlock the menu to
allow changes.
When the delay time for all speaker positions has
been set, you may return to the manual setup by
pressing the /
⁄ ¤
until the cursor points to BACK TO MANUAL
SETUP and then pressing the OK/Enter Button
E on the TC 30 or the Set Button œ. However,
if you have a digital video source or a digital video dis-
play that causes lack of lip sync, you may use the A/V
/
⁄ ¤
sync adjust feature to delay the audio signal as it is
sent to all channels (as opposed to the individual set-
tings) so that the picture and sound are brought back
together. We recommend that this adjustment be
made using the direct-access controls on the remote,
/
⁄ ¤
as shown below. That enables you to see the image
while making the adjustment; however, you may also
adjust it here using the menu system.
To adjust the A/V sync delay, press the
Buttons D© so that the cursor is pointing to the
A/V SYNC DELAY line in the menu and then
Navigation Buttons D© to
press the ‹ / ›
delay the sound until it matches the on-screen video.
The delay settings may also be adjusted directly and
without going into the OSD menu system at any time
using the TC 30 remote control and while viewing an

/
on-screen image. This is particularly helpful in the case
of the A/V sync delay, since it is important to be able
to view the impact of the A/V sync delay adjustment
with on-screen images.

To adjust the delay settings, first try to have a program
on the video display that has close-ups and dialogue.
If you feel that the audio is ahead of the picture, look
closely at the actors' lips when they stop speaking,
and notice whether their lips move for a short duration
after the dialogue has stopped. When using the delay
adjustments, change the setting so that the movement
of the actors' lips is in sync with the sound, so that the
sound stops when their lips stop. This is a good way
to get the image and sound locked together.
The controls for A/V sync delay are activated by first
pressing the Devices Button 4 on the TC 30, and
then pressing the Screen Button 6 at the top of
the left vertical row, to the right of the AVR image in
the remote's screen. When the images in the LCD
change, press the Screen Button 6 to the left of
the box with the word DELAY.
Within five seconds, when the A/V SYNC
DELAY message appears in the Lower Display
, press the OK/Enter Button E and then
Line
Navigation Buttons D© to bring
use the /
‹ ›
the image and sound into sync. When you have com-
pleted the adjustments, press the OK/Enter Button
E again to enter the setting into the system memory.
When a 480i image is being viewed, you will see the
A/V sync time message appear as a semi-OSD on-
screen message, as well as in the front-panel display.
Semi-OSD messages are not available when 480p or
higher resolution video is in use.
To change the delay setting for an individual speaker
setting directly, rather than the A/V sync "group delay,"
follow these same instructions, but when the A/V
SYNC DELAY message appears, press the
Navigation Buttons D© until the desired
/
‹ ›
speaker position name appears, and then press the
OK/Enter Button E to start the selection, the
Navigation Buttons D to change the delay
/
‹ ›
settings, and finally the OK/Enter Button E to
store the setting.
Note that the A/V sync delay setting is unique to
each video input source, so you may enter a different
setting to compensate for the differences with any
product attached to the different inputs.
When all changes to the Delay settings have been

made, press the /
⁄ ¤
until the cursor is on the BACK TO MANUAL
SETUP menu and then press the OK/Enter
Button E on the TC 30 or the Set Button œ
so that you may make any other adjustments to the
system parameters. If the changes just made complete
the manual adjustments needed, press the Menu A
or OSD Button ∫ to exit the menu system and
resume normal system operation.
