SYSTEM CONFIGURATION 29
System Configuration
When any needed adjustments are made to the
crossovers, one additional adjustment is available
to custom tailor the way information is sent to the
subwoofer. The
LFE LP FLT line adjusts the
frequency cutoff of the low pass filter that deter-
mines the frequency at which information is sent
to the subwoofer when playing a digital sound-
track 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 chan-
nels during a movie’s sound mixing process.
However, you may wish to change the setting
based on your individual preference or the charac-
teristics and capabilities of your subwoofer.
To change this setting when the SPEAKER
X-OVER menu is on the screen, press the
⁄ / ¤ Navigation Button E until the cursor
is on the LFE LP FLT line and then press
the ‹ / › Navigation Button E until the
desired setting is shown in highlighted video.
When all changes to Speaker Crossover settings
have been made, press the
⁄ / ¤ Navigation
Button E until the cursor is on the
BACK
T O MANUAL SETUP menu and then press-
ing the Set Button F 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 26 for using the
Manual mode.
The Speaker Configuration may also be changed
at any time without using the full-OSD on-screen
menu system by pressing the Speaker Selector
6 on the front panel or
b on the remote con-
trol. Once the button is pressed, FRONT
SPEAKER will appear in both the lower third
of the video display and the Main Information
Display ˜.
Within five seconds, either press the ‹ / › buttons
7 $ on the front panel or the ⁄ / ¤ buttons
E on the remote to select a different speaker
position, or press the Set Button @
F to begin
the adjustment process for the front left and right
speakers.
When the Set button @ F has been pressed
and the system is ready for a change to the front
speaker setting, the on-screen display and Main
Information Display ˜ will read
FRONT
LARGE or FRONT SMALL depending on
the current setting. Press the ‹ / › buttons 7 $
on the front panel or the ⁄ / ¤ buttons E on
the remote until the desired setting is shown,
using the instructions for “large” or “small”
shown earlier, then press the Set button @
F.
If another speaker position needs to be changed,
press the
‹ / › buttons 7 $ on the front panel
or the ⁄ / ¤ buttons E on the remote to select
a different speaker position, press the Set button
@
F and then the
‹ / › buttons 7 $ on the
front panel or the ⁄ / ¤ buttons E on the
remote until the correct speaker setting is shown
and press the Set button @
F again to con-
firm the selection.
To assist in making these settings, the icons in the
Speaker/Channel Input Indicators Ú will
change as the speaker type is selected at each
position. When only the inner icon box is lit, the
speaker is set for “small.” When the inner box and
the two outer boxes with circles inside them are
lit, the speaker is set for “large." When no indica-
tor appears at a speaker location, that position is
set for “none” or “no” speaker.
Note: These icons are available only when
making setup changes without the use of the full
OSD mode.
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 sur-
round 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.
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) speak-
ers in meters.
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 nonstan-
dard system configuration. To change the settings,
follow the instructions below to enter the distance
between the speaker’s location and your main lis-
tening position. The measurements need not be
accurate to the inch, as the system is designed to
accommodate typical listening rather than a spe-
cific “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 per-
sonal 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.
The Delay setting for all speakers configured for
your system will be available only (with 5.1 or
with 6.1/7.1 configuration) when any Dolby sur-
round mode is selected (except Dolby-3-Stereo).
In addition they are selectable with these modes
only, with all other modes the delay times are
fixed. Note that the Delay settings are "Global"
for all inputs, using those Dolby modes, and need
not to be repeated with any input.
