until the desired setting appears. The available
choices at which point low-frequency information
will be sent to the subwoofer (or to the Front
Left/Right speakers in case subwoofer is set to
OFF), rather than to the 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 lowfrequency limit to avoid
the creation of a low-frequency "hole" where
your system will have no bass information.
In cases where has been selected as the
LARGE
front channel speaker option and
L/R+LFE
has been selected as the subwoofer option, the
front channel sound information below the cross-
over point selected for the L/R front speakers
(when fronts are set to "Small") will be sent to
BOTH the front channel speakers and the sub-
woofer.
The crossover settings for the Left/Right, Center,
Surround and Surround Back speakers are used
to determine where bass information is sent
when it is derived from the main channels of a
source. The setting for the menu line shown as
is used to impose a low-pass filter point for
LFE
the information in the Low Frequency Effects
(LFE) channel that is a part of Dolby Digital- and
DTS-encoded source material. While the LFE
channel, which is the ".1" you see in surround
sound designations, is restricted to low fre-quen-
cy sounds, some mixes may include information
that is higher in frequency than your subwoofer is
capable of reproducing. To prevent unwanted
sounds from being sent to subwoofers that
cannot handle them and which do not have a
built-in low-pass filter, the option line
LFE
enables you to select a setting for the low-pass
filter that is part of the subwoofer feed from the
LFE channel. The settings available are the same
as those tied to any one of the four available
speaker positions on this submenu. We recom-
mend that you use the frequency that is just
slightly higher than the upper capability limit of
your subwoofer, as shown in the sub's Owner's
Manual. When the cursor is on the
press the / Navigation Buttons

choose the appropriate setting.
Note that the crossover point for the surround
speakers and the surround back speakers will be
identical. That´s why no crossover point for the
surround back speakers is selectable or shown in
the menu.

Important Note: All settings for the crossover
points will be "Global", i.e. they will be identical
until the cur- for all inputs no matter if the BASSMANAGER
(see above) was configured for "Global" or
"Independent".

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 specific
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 nonstan-
dard system configuration. To change the set-
tings, 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 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.
Although EzSet+ calculates the delay settings for
the individual speaker positions with very
accurate 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
display 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
outlined below.
