Harman-Kardon AVR 240 - Manual (Page 29)

Figure 13
To change the setting for any of the four speaker
groups, press the
⁄ / ¤ Buttons n until the cursor
is next to the line where you wish to make a change,
and then press the
‹ / › Buttons o until the
desired setting appears. The available choices that
determine at which point low-frequency information
will be sent to the subwoofer, rather than to the 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-fre-
quency “hole” where your system will have no bass
information.
NOTE: In cases where LARGE is selected as the
front channel speaker option and LFE+L/R is
selected as the subwoofer option, the front channel
sound information below the setting shown will
be sent to BOTH the front channel speakers and
the subwoofer.
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 LFE is used
to impose a low-pass filter point for 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-
quency 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
LFE option line 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 recommend
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 LFE line, press the ‹/›
Buttons o to choose the appropriate setting.
When all speaker selections have been made, press
the
¤ Button n and then the Set Button p
to return to the MANUAL SETUP submenu.
Delay Settings
Due to the different distances between the listening
position for the front channel speakers and the sur-
round speakers, the amount of time it takes for sound
to reach your ears from the front versus surround
speakers differs. You may compensate for this differ-
ence 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 addition to adjusting the delay time for each individ-
ual speaker position, the AVR 240 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 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.
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 man-
ually, 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.
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 personal preferences. To change
the settings, 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.
Due to the differences in the way each surround
mode operates, the delay settings must be established
individually for each surround mode. Once the delay
settings are configured for the version of the surround
mode with the most channels, they need not be
entered again for a version of that mode with fewer
channels. For example, once the delay settings are
established for Dolby Pro Logic IIx – Movie, they will
be carried over to Dolby Pro Logic II – Movie mode.
However, you will need to enter the delay settings
separately for each variant mode (e.g., Dolby Pro
Logic IIx – Music, Dolby Pro Logic IIx – Game, Dolby
Pro Logic, Dolby 3 Stereo and Dolby Digital EX).
Delay times are adjustable for all surround modes.
Although all channels will appear on screen with the
default or previously entered distances, the menu sys-
tem will only allow you to adjust the settings for those
channels which are actually used by the current sur-
round mode. For example, when you are listening to
music CDs using the CD input in DSP Surround Off
mode, you may adjust the delay settings for the front
left, front right and subwoofer channels only. The cur-
sor will simply skip the other channels as you navigate
through the menu. Therefore, the first time you adjust
the delay settings, it is recommended that you select a
5.1-, 6.1- or 7.1-channel surround mode, depending
on the number of speakers in your system. For the
purposes of setting the delay distances, the Logic 7
modes allow access to the settings for all channels
without requiring that you play a source.
To set the delay time for a specific input, the
DELAY ADJUST submenu (Figure 10) should
be visible on your on-screen display. If it is not, press
the OSD Button v to bring up the
MASTER
MENU, and press the ¤ Button n until the
on-screen › cursor is pointing at the MANUAL
SETUP line. Press the Set Button p to enter
the
MANUAL SETUP submenu, and then scroll
down using the ¤ Button n until the › cursor
is pointing to the DELAY ADJUST line. Press
the Set Button p again, and the DELAY
ADJUST submenu will appear (see Figure 14).
Figure 14
Once the DELAY ADJUST menu is on your
screen, note that the default setting to enter the dis-
tances from the speakers to the listening position is in
feet. If your measurements are in feet, proceed to the
next step; if your measurements are made in meters,
press the
¤ Button n until the on-screen › cursor
is at the UNIT line on the menu. Then, press the
‹ / › Buttons o so that METER is highlighted.
When the change in measurement units is made,
press the
⁄ / ¤ Buttons n to return the › cursor
to the FL position.
