Delay Settings - Harman Kardon AVR 247 Owner's Manual

System Configuration
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
compensate 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.
If you have already calibrated your system using
EzSet/EQ the delay settings shown will reflect
the results of the measurements made by
EzSet/EQ. No further changes are needed unless
you wish to change an item to reflect your taste
or a nonstandard system configuration. To
change the settings, follow the instructions
below to enter the distance between the
speaker's location and your main listening
position. The measurements need not be
accurate to the centimeter, as the system is
designed to accommodate typical 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 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.
Although EzSet/EQ calculates the delay settings
for the individual speaker positions with very
accurate results, 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. Thus, even though you
may have used EzSet/EQ for other delay settings,
the A/V Sync Delay should still be configured as
outlined below.
32 SYSTEM CONFIGURATION
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, surround and surround back (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.
For example, once the delay settings are
established for Dolby Pro Logic IIx – Movie, they
will be carried over to Dolby Pro Logic II – Movie
mode. However, you will need to enter the delay
settings separately for each variant mode, such
as Dolby Pro Logic IIx – Music, Dolby Pro
Logic IIx – Game, Dolby Pro Logic,
Dolby 3 Stereo and Dolby Digital EX.
Delay times are adjustable for all surround
modes. Although all channels will appear on
screen with the default or previously entered
distances, 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 recommended that you select a
5.1-, 6.1- or 7.1-channel surround mode,
depending on the number of speakers in your
system. 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

Button F. Now press the

speaker to the preferred listening position is
entered followed by the Set Button F to
confirm your choice. Next press the
D once to move to the next line.
Now the blue bar will highlight the
line so that the delay for the center speaker may
be set. Press Set F followed by the 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
D again and use the
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 main menu
by pressing the
‹
several times.
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

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 Set
