cursor is next to the line where you wish to make
a change and then press the Buttons
/
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 and 200Hz.
Pick the choice that is identical to the informa-
tion 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 cre-
ation of a low-frequency "hole" where your sys-
tem will have no bass information.
The setting for the crossover point for the LFE
channel, which is created to provide specific low-
frequency information in many movies with digi-
tal 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 recom-
mend that you select the speaker group whose
crossover point is closest to 120Hz. To do this,
press the / Navigation Button

changed at any time without using the full-OSD
on-screen menu system by pressing the Speaker

Within five seconds, either press the

To assist in making these settings, the icons in
the Speaker/Channel Input Indicators
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
indicator 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.

line and 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
on the
speaker placement and acoustic conditions in
your listening room or home theater.

to 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
on
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
on the front panel modes operate, some modes allow for a greater
on the remote to range of delay times than others. To avoid prob-
lems, we recommend that delay times be adjust-
buttons ed using the Dolby Digital mode. If a different
/

/
will automatically select the closest delay settings
again available for the surround mode in use.
Delay times are adjustable only for the Dolby and
DTS modes, so you will notice that the
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, adjust-
ments may be made to the Surround speakers
only.
To start with the delay settings at first select any
input associated with such a Dolby mode. Next,
