Delay Settings - Harman Kardon AVR 240 Owner's Manual

System Configuration

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 specif-
ic speaker placement and acoustic conditions in
your listening room or home theater.
If you have already calibrated your system using
EzSet+ the delay settings shown will reflect the
results of the measurements made by EzSet+.
No further changes are needed unless you wish
to change an item to reflect your taste or a non-
standard 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 inch, 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 process-
ing 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 elimi-
nate the loss of lip sync that may be caused by
digital video applications.
Although EzSet+ calculates the delay settings for
the individual speaker positions with very accu-
rate 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 dis-
play while adjusting the delay, if any, required for
the specific source. Thus, even though you may
have used EzSet+ for other delay settings, the
A/V Sync Delay should still be configured as out-
lined 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, 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 estab-
lished 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 estab-
26 SYSTEM CONFIGURATION
lished 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 dis-
tances, the menu system will only allow you to
adjust the settings for those channels which are
actually used by the current sur-round 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-, 6.1- or 7.1-chan-
nel surround mode, depending on the number of
speakers in your system. For the purposes of set-
ting the delay distances, the Logic 7 modes allow
access to the settings for all channels without
requiring that you play a source.

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.
