Speaker Crossover Setting; Delay Settings - Harman Kardon AVR 435 Owner's Manual

SYSTEM CONFIGURATION SYSTEM CONFIGURATION
• If a subwoofer is connected to the AVR 435, you
have the option to have the front left/right "main"
speakers reproduce bass frequencies at all times,
and have the subwoofer operate only when the
AVR 435 is being used with a digital source that
contains a dedicated low-frequency effects, or LFE
soundtrack. This allows you to use both your main
and subwoofer speakers to take advantage of the
special bass sounds created for some movies.

receive LFE information and the bass frequencies
under the selected crossover point.

to move the cursor to the SUB SIZE line. The
setting on this line enters the data of the size of your
subwoofer's driver so that the proper gain, filters and
equalization settings will be used with EzSet/EQ.
To change the setting, make certain that the cursor is
on the SUB SIZE line and press the
Navigation Button o, so that the setting appears
that matches the diameter of your subwoofer's driver.
If you do not remember what the size is, you can
either measure the driver's diameter or consult the
owner's manual for the speaker.

important to remember to re-run the EzSet/EQ system
if any changes have been made to the settings on this
menu, following the instructions shown on page 24 for
using the Manual mode.

Speaker Crossover Setting

When all speaker "size" settings have been made,
you now have the option to take advantage of the
AVR 435'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
28 28 SYSTEM CONFIGURATION SYSTEM CONFIGURATION
speaker's internal low-frequency driver, as opposed to
the mid-range driver. The settings on the SPKR X-
OVER menu also allow you to set the high pass filter
that determines which frequencies go to the subwoofer
when the AVR 435 is playing back the low frequency
effects (LFE) channel from a digital soundtrack.
Before making any changes to the settings on this dis-
play, we suggest that you find the crossover point for
the speakers in each of the four groupings, and the
highest frequency handled by your subwoofer as well
as the order of its filter slope. 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 speaker manufac-
turer's Web site, or by contacting your dealer or the
manufacturer's customer service department. You will
need these figures 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.
To make changes to the speaker crossovers or LFE
high-pass filter setting, go to the SPKR X-OVER
submenu within the MANUAL SETUP menu
(Fig. 16). To do this, first press the OSD Button
so that the MASTER MENU (Figure 1) appears.

main speaker channel, are 40Hz, 60Hz, 80Hz,
100Hz, 120Hz, 150Hz 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.
When any needed adjustments are made to the
crossovers, one additional adjustment is available to
custom tailor the way information is sent to the sub-
woofer. The LFE LP FLT line adjusts the fre-
quency cutoff of the low pass filter that determines the
frequency at which information is sent to the sub-
woofer when playing a digital soundtrack that has a
dedicated low frequency effects channel. In most
cases the default frequency of 120Hz is appropriate,
since that is the frequency most commonly used in
the creation of LFE channels during a movie's sound
mixing process. However, you may wish to change the
setting based on your individual preference or the
characteristics and capabilities of your subwoofer.
To change this setting when the SPEAKER
X-OVER menu is on the screen, press the
Navigation Button o until the cursor is on the
LFE LP FLT line and then press the
Navigation Button o until the desired setting is
shown in highlighted video.
When all changes to Speaker Crossover settings have

been made, press the /

until the cursor is on the BACK TO MANUAL
SETUP menu and then pressing the Set Button
q so that you may make any other adjustments
to the system parameters. It is also important to
remember to rerun the EzSet/EQ system if any
changes have been made to the settings on this
menu, following the instructions shown on page 24
for using the Manual mode.

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.
In most cases, the settings established by EzSet/EQ
are accurate to under a foot, but the placement of
the microphone and other factors may influence
the setting. Should you wish to manually adjust the
channel delay times, follow the instructions shown
below. Whenever adjustments to the delay settings are
made remember that the distance settings need not
be accurate to the inch, as the system is designed to
accommodate a typical listening area rather han the
precise measurement from the speakers to a specific
"sweet spot" position.
