Delay Settings - Harman Kardon AVR 7300 Owner's Manual

SYSTEM CONFIGURATION SYSTEM CONFIGURATION
speaker configuration and crossover settings.
NOTE: The independent feature allows you to select a
different speaker size configuration (Large, Small or
None, as appropriate) for each input source. However,
the individual crossover point setting may only be set
once, and the selection made during the initial setup
will be used for all inputs, regardless of any changes
made to the "Large" or "Small" settings for the speaker
groups attached to any input. The reason is that while
you may prefer different settings for the bass redirec-
tion (that is, which signals go to the subwoofer or the
speaker group), the actual crossover point remains the
same since the actual loudspeakers themselves
remain the same regardless of any other setting.
When all speaker selections have been made, press

Delay Settings

Due to the different distances between the listening
position and each speaker position, the amount of
time it takes for sound to reach your ears from each
channel is different. You may compensate for this dif-
ference through the use of the delay settings to adjust
the timing for the speaker placement and acoustic
conditions in your listening room or home theater.
The AVR 7300's advanced software enables you to
quickly and easily set delay times without the need to
calculate them using a complex formula. Instead, all
you need to do is measure the approximate distance
between your listening position and each of the speak-
ers in your system. When you enter those distances
into the AVR's memory as shown below, the AVR's
microprocessor does the rest of the work, calculating
the proper delay time. The measurements need not be
accurate to the inch, as the system is designed to
accommodate a typical listening area rather than
require the precise measurement to one "sweet spot"
position.
In addition to adjusting the delay time for each individ-
ual speaker position, the AVR 7300 is among the few
receivers that allows you to adjust the delay for the
combined output of all speakers as a group. This fea-
ture is called A/V Sync Delay; it allows you to com-
pensate 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.

Due to the differences between the way surround
modes operate, some modes allow for a greater range
of delay times than others. To avoid problems, we rec-
ommend that delay times be adjusted using the Dolby
Digital mode. If a different mode is selected at a later
time, the AVR 7300 will automatically select the
closest delay settings available for the surround
mode in use.
Delay times are adjustable only for the Dolby and DTS
modes, so you will notice that the DELAY menu
may not be accessed for other modes, such as Logic 7.
In addition, when a non-Dolby Digital mode such as
Pro Logic II is selected, adjustments may be made to
the Surround speakers only.
To set the delay time for a specific input, the
DELAY ADJUST menu (Fig. 9) should be visi-
ble in your on-screen display. To select that menu,
bring up the AUDIO SETUP menu and press
the Navigation Button o until the on-screen
¤
➔ cursor is pointing at the DELAY ADJUST
line. Press the Set Button q to call up the menu.

When a digital video source or a digital video display
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 channels) so
that the picture and sound are brought back into sync.
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 mak-
ing the adjustment. However, you may also adjust it
here using the menu system.
To adjust the A/V Sync delay, press the
Navigation Button o so that the ➔ cursor is
pointing to A/V SYNC DELAY on the menu;
then press the ‹
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
The A/V Sync Delay setting is first, and it may be
adjusted by pressing the Set Button q 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 o to enter the desired delay
setting that brings the video and sound back in sync.
Press the Set Button q 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 set-
ting to compensate for the differences between any
product attached to the DVD or Video inputs.
