Delay Settings - Harman Kardon AVR 630 Owner's Manual

• If a subwoofer is connected and you wish to use it
for bass reproduction in conjunction with the main
front left/right speakers, regardless of the type of
program source or Surround mode you are listen-

the remote so that SUB L/R+LFE appears
in the on-screen menu. When this option is select-
ed, a full-range signal will be sent to the front
left/right "main" speakers, and the subwoofer will
receive LFE information and the bass frequencies
under the selected crossover point.
When all initial speaker "size" settings have been
made, you now have the option to take advantage of
the AVR 630's Quadruple Crossover system, which
allows individual crossover settings to be made for
each speaker grouping. The low-frequency crossover
point is set by the design of your speakers. Depending
on the design and driver complement of your speakers,
it is defined as the frequency which is either the lowest
possible frequency the speaker is capable of repro-
ducing, or the frequency at which sound is sent to the
speaker's internal low-frequency driver, as opposed to
the mid-range driver.
Before making any changes to the settings for
the crossover point, we suggest that you find the
crossover point for the speakers in each of the four
groupings, front left/right, center front, surround and
surround back, by looking at the specifications page
of each speaker's owner's manual, by getting that
information from the manufacturer's Web site, or
by contacting your dealer or the manufacturer's
customer service department. You will need this figure
to accurately configure the next group of settings.
Note that when any speaker group other than the front
left/right speakers is set to LARGE, the crossover
may not be adjusted, as the feed will be full-range,
with no sound being derived for the subwoofer at
that position.
The factory default setting for all speaker positions is
100Hz. If that setting is acceptable for all channels,
then no adjustments are needed and you may skip
this section. However, should you wish to change
one of the settings, please proceed by pressing the
Navigation Button o so that the cursor
⁄
moves back up to the MODE line. Press the
Navigation Button o so that X-OVER is high-
lighted and the menu data will change to the screen
shown in Figure 7.

the cursor is next to the speaker group where you
wish to make a change and then press the
Navigation Button o until the desired setting
appears. The available choices for low-frequency infor-
mation to be sent to the subwoofer, rather than to the
main speaker channel, are 40Hz, 60Hz, 80Hz,
100Hz, 120Hz and 200Hz. Pick the choice that is
identical to the information for the speakers, or if an
exact match is not possible, pick the closest choice
that is ABOVE the speaker's low-frequency limit or
crossover point to avoid the creation of a low-
frequency "hole" where your system will have no
bass information.
The setting for the crossover point for the LFE chan-
nel, which is created to provide specific low-frequency
information in many movies with digital soundtracks,
may be set to match the crossover for any of the four
speaker groups. Since the crossover point commonly
used in the creation of the LFE channel is 120Hz, we
recommend that you select the speaker group whose
crossover point is closest to 120Hz. To do this, press
Navigation Button o until the cursor
the /

is next to the LFE line, and then press the
Navigation Button o until the name of the
speaker group with the desired crossover frequency
appears. Of course, you may also experiment with
different settings to find the one that provides the
smoothest and most complete bass response in your
particular listening environment.
When all crossover settings have been made, or in
those cases where none are needed, press the
Navigation Button o so that the cursor is next to
the BASS MGR line to make the final setting on

this menu.
This setting allows you to use the same speaker con-
figuration and crossover settings for all inputs, or to
have different settings for each input. In most cases,
the factory default setting of GLOBAL will be
appropriate, as most listeners do not need to have
individualized speaker settings. However, some listen-
ers, particularly those with full-range front speakers
that are used for both movies and music, may prefer
that different crossover points be used when listening

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 630'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
speakers in your system. When you enter those dis-
‹ / ›
tances into the AVR's memory as shown below, the
AVR's microprocessor does the rest of the work, cal-
culating 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 630 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 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.
