Note: These icons are available only when
making setup changes without the use of the full
OSD mode.
As an example, in the Figure below, all speakers
are set for “large,” and a subwoofer is set.
Delay Settings
Due the different distances between the listening
position for the front channel speakers and the
surround speakers, the amount of time it takes
for sound to reach your ears from the front or
surround speakers is different. You may compen-
sate for this difference through the use of the
delay settings to adjust the timing for the specific
speaker placement and acoustic conditions in
your listening room or home theater.
To change the settings, follow the instructions
below to enter the distance between the speak-
er’s location and your main listening position. The
measurements need not be accurate to the inch,
as the system is designed to accommodate typi-
cal listening rather than a specific “sweet spot”
position.
In addition to adjusting the delay time for each
individual speaker position, the AVR is among the
few A/V receivers that allows you to adjust the
delay for the combined output of all speakers 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
products such as digital video displays, video
scalers, digital cable or satellite systems, or per-
sonal 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.
The setting for A/V Sync Delay may only be done
manually, since it requires that you observe the
program material on your video display while
adjusting the delay, if any, required for the
specific source. The A/V Sync Delay should still be
configured as outlined below.
To re-synchronize the front, center and surround
channels at first measure and note the distance
from the listening/viewing position to the front,
center and surround (if any) speakers in meters.
Due to the differences in the way each surround
mode operates, the delay settings must be
established individually for each surround mode.
However, once the delay settings are configured
for the version of the surround mode with the
most channels, they need not be entered again
for a version of that mode with fewer channels.
However, you will need to enter the delay settings
separately for each variant mode, such as Dolby
Pro Logic II – Music, Dolby Pro Logic II – Game,
Dolby Pro Logic, Dolby 3 Stereo.
Delay times are adjustable for all surround
modes. Although all channels will appear on
screen with the default or previously entered dis-
tances, the menu system will only allow you to
adjust the settings for those channels which are
actually used by the current surround mode. For
example, when you are listening to music CDs
using the CD input in DSP Surround Off mode,
you may adjust the delay settings for the front
left, front right and subwoofer channels only. The
cursor will simply skip the other channels as you
navigate through the menu. Therefore, the first
time you adjust the delay settings, it is recom-
mended that you select a 5.1-channel surround
mode. For the purposes of setting the delay
distances, the Logic 7 modes allow access to the
settings for all channels without requiring that
you play a source.
To start with the delay settings at first select the
DELAY ADJUST MENU (Figure 9). If the sys-
tem is not already at that point, press the OSD
button
L to bring up the master menu. Press
the ¤ Button D three times or until the on-
screen fi cursor is pointing at the MANUAL
SETUP line. Press the OK Button F and call
up the DELAY ADJUST submenu.
Figure 9
Next move the fi cursor to the UNIT line and
select the unit for distances you prefer to enter,
feet or meter. Then move the
fi cursor to the FL
line where the first adjustment is made. Now
press the
‹ / › Buttons Ea until the dis-
tance from the front left speaker to the preferred
listening position is entered. Next press the
¤ Button D once to move to the next line.
Now the fi cursor will be at the CEN line so
that the delay for the center speaker may be set.
Press the
‹ / › Buttons Ea until the
distance from the main listening position to the
center speaker is entered.
Repeat the procedure for all active speaker
positions by pressing the
¤ Button D again
and use the ‹ / › Buttons Ea to change the
setting. Remember that this last adjustment will
only be needed when you have surround back
speakers installed and Dolby Digital chosen as
the surround mode.
When the delay time for all speaker positions has
been set you may return to the master menu by
pressing the
⁄ / ¤ Navigation Button D
until the fi cursor is pointing to BACK TO
MASTER MENU and then pressing the OK
Button F.
However, if you have a digital video source or a
digital video display 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 settings) 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 ⁄ / ¤
Navigation Button D so that the fi cursor is
pointing to the A/V Sync Delay line on the menu
and then press the
‹ / › Navigation Button
Ea to delay the sound sufficiently so that it
matches the on-screen video.
The delay settings may be adjusted at any time
using the remote control and while viewing an
on-screen image by pressing the Delay Select
Button
Z. The A/V Sync Delay setting is first,
and it may be adjusted by pressing the OK
Button
F within five seconds of when the
A/V SYNC DELAY message appears in the
on-screen display and the Lower Display Line
˜. Then, press the
‹ / › Navigation Button
Ea to enter the desired delay setting that
brings the video and sound back in sync. The A/V
Sync delay time may be set in 1 millisecond inter-
vals up to 180 ms. Press the OK Button
F
again to enter 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 differ-
ences between any product attached to the
Video 1, 2 or 3 inputs.
To change one of the individual speaker positions
directly, press the Delay Select Button
Z,
followed by the ⁄ / ¤ Navigation Button D
to select the desired position as that name
appears in the on-screen display and the Main
Information Display
Ò. When the name of
the speaker position to be adjusted appears press
the OK Button
F within five seconds. Press
the ‹ / › Navigation Button Ea to enter
the desired delay setting for that speaker and
then press the OK Button
F to enter the set-
ting. The ⁄ / ¤ Navigation Button D may
be used to select another position, or you may
simply wait five seconds for the system to time
out and return to normal operation.
