n addition to providing delaying adjustments for each

ndividual 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

mage 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

elay, you can eliminate the loss of lip sync that may

e 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

to move the cursor to DELAY

ADJUST

and then press the OK/Enter Button

E on the TC 30 or the Set Button

on the

ZR 10. The

DELAY ADJUST menu (Figure

29) will appear on the screen.

Figure 29

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,

press the

Navigation Buttons D

until the

on-screen cursor is at the

UNIT line on the menu.

Then, press the

‹

›

Navigation Buttons D

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

⁄

viga

tion

Button

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the factory defaults are no longer in effect.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

‹

›

viga

tion Button

to move the cursor to the next line and use

‹

›

avigation Buttons

gain to

enter the distance from the main listening position to

the center speaker. Repeat the procedure for all active

speaker positions, first using the

⁄

Navigation

uttons

o change to the next position;

hen use the

‹

›

avigation Buttons

change the setting. Note that only the speaker posi-

tions that have been set to

LARGE or SMALL

in the SPEAKER SIZE menu, as shown on

age 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/EQ, return to the settings

established by the automated system by pressing the

⁄

Navigation Buttons D

until the cursor

is pointing to the

EZSET SETTINGS line.

Next, press the

‹

›

Navigation Buttons D

so that ON is highlighted in reverse video. The set-

tings will be resent to the values calculated

by EzSet/EQ, 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

⁄

Navigation Buttons D

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

. 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.

o adjust the

A/V sync delay,

press the

⁄

viga

tion

Buttons

so that the cursor is pointing to the

A/V SYNC DELAY line in the menu and then

press the

‹

›

Navigation Buttons D

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.

o 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,

nd notice whether their lips move for a short duration

after the dialogue has stopped. When using the delay

djustments, 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

Line

D, press the OK/Enter Button E and then

use the

‹/› Navigation Buttons D

to bring

the image and sound into sync. When you have com-

pleted the adjustments, press the

OK/Enter Button

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

‹/› Na

vigation 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

⁄

vigation Buttons

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

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
