Harman-Kardon AVR 240 - Manual (Page 28)

When SMALL is selected, the system will adjust so
that the full complement of 6.1/7.1 surround processing/
decoding modes are available, and low-frequency
information below the crossover point will be sent
to the subwoofer output. If you choose this option
and there is no subwoofer connected, you will not
hear any low-frequency sounds from the surround
back channel.
When LARGE is selected, the system will adjust so
that the full complement of 6.1/7.1 surround process-
ing/decoding modes are available, and a full-range
signal will be sent to the surround back channels,
with no low-frequency information sent to the sub-
woofer output.
NOTE: Although Harman Kardon strongly recommends
using two surround back speakers, we recognize that
some users may have only a single surround back
speaker. It is possible to set up a 6.1-channel system
by following this procedure:
Set the surround back speakers to NONE in the
SPEAKER SIZE menu. Then run the EzSet+
procedure for a 5.1-channel system.
Now you may connect the single speaker to the LEFT
Surround Back Speaker Output
9. Use the
SPEAKER SIZE menu to configure the left
surround back channel. The output levels, delay set-
tings and crossover settings will all have to be set
manually for the surround back speaker.
If you choose to operate the receiver in only a 6.1-
channel configuration, keep in mind that if a 7.1-chan-
nel surround mode, such as Dolby Pro Logic IIx or
Logic 7/7.1, is selected, then certain back surround
information will be lost. Therefore, this workaround is
recommended only as a last resort where it is not pos-
sible to connect separate left and right surround back
loudspeakers.
When you have completed your selection for the back
surround channels, press the
¤ Button n on the
remote to move the cursor to SUBWOOFER.
Press the ‹ / › Buttons o on the remote to select
the option that best describes your system.
The choices available for the subwoofer position will
depend on the settings for the other speakers, particu-
larly the front left/right positions.
If the front left/right speakers are set to SMALL, the
subwoofer will automatically be set to SUB, which is
the “on” position.
If the front left/right speakers are set to LARGE,
three options are available:
• If no subwoofer is connected to the AVR 240,
press the ‹ / › Buttons o on the remote so
that NONE appears in the on-screen menu.
When this option is selected, all bass information
will be routed to the front left/right “main” speakers.
• If a subwoofer is connected and you wish to have
the front left/right “main” speakers reproduce bass
frequencies at all times, and have the subwoofer
operate only when the AVR 240 is being used with
a digital source that contains a dedicated Low-
Frequency Effects, or LFE, soundtrack, press the
‹ / › Buttons o on the remote so that LFE
appears in the on-screen menu.
• If a subwoofer is connected and you wish to use
it for bass reproduction in conjunction with the
main front left/right speakers, regardless of the
type of program source or Surround mode, press
the
‹ / › Buttons o on the remote so that
SUB LFE+L/R appears in the on-screen
menu. When this option is selected, a full-range
signal will be sent to the front left/right “main”
speakers, and the subwoofer will receive the
bass frequencies under frequency selected, as
described below, as well as the LFE information.
When all size settings have been made (or in those
cases where none are needed), press the
¤ Button
n so that the cursor is next to the BASS MGR
line to make the final setting on this menu.
This setting allows you to use the same speaker size
configuration for all inputs, or to have different settings
for each input. In most cases, the factory default set-
ting of
GLOBAL will be appropriate, as most listen-
ers do not need to have individualized settings.
However, some listeners, particularly those with full-
range front speakers that are used for both movies
and music, may prefer that different bass management
be used when listening to music through a CD player
as opposed to a movie from a DVD player, VCR or
cable/satellite set-top. Also, you may wish to activate
or deactivate certain speakers for some sources. For
example, when listening to CDs, you may wish to have
only the front left and right speakers active, or for
watching TV, you may wish to deactivate the surround
back speakers in favor of a 5.1-channel configuration.
If you wish to customize the speaker settings for
each input, make certain that the
› cursor is on the
BASS MGR line, and press the ‹ / › Buttons o
so that INDEPENDENT appears. When this
setting is entered by exiting the menu, you may need
to go back to the
INPUT menu to select another
input, and then return to this menu page again to
change the settings for that input. Repeat the proce-
dure for any input where you wish to have a different
set of speaker configurations.
NOTE: When the INDEPENDENT setting is
activated, you may assign different speaker size set-
tings to each input to accommodate different bass
management settings that match your preferences with
the type of program material normally used with a par-
ticular source (for example, when movies are played
from DVD and music from a CD player). However, the
actual speaker crossover settings are set only once and
do not change with the input selection. The reason is
that, while bass management preferences may vary,
the actual speakers remain the same, regardless of the
bass management and redirection settings.
Speaker Crossover Settings
When all initial speaker “size” settings have been
made, you now have the option to take advantage of
the AVR 240’s Quadruple Crossover system, which
allows individual crossover settings to be made for
each speaker grouping. In systems where full-range
or tower speakers are used for the front soundstage
or where different brands or models are in use at the
various speaker positions, this feature allows you to
customize the bass management and redirection
circuits with a precision not previously possible.
If you have already completed an automated setup
using EzSet+ the settings calculated during that proce-
dure will already appear. No further adjustment is
required unless you wish to change a specific item to
reflect your personal taste or a nonstandard system
configuration.
The low-frequency crossover setting is determined by
the design of your speakers. Depending on the design
and driver complement of your speakers, it is usually
the lowest possible frequency the speaker is capable
of reproducing. Before making any changes to the set-
tings for the crossover point, we suggest that you find
the lowest frequency for the speakers in each of the
three groupings, front left/right, center and surrounds,
by looking at the specifications page of each speaker’s
owner’s manual, or by contacting your dealer or the
manufacturer’s Customer Service department or Web
site. You will need this figure to accurately configure
the next group of settings.
The factory default setting for all speaker positions is
100Hz. If that setting is acceptable for all channels,
then no adjustments are needed and you may skip this
section. However, if you wish to change one of the
settings, proceed to the
SPEAKER X-OVER
submenu by pressing the ¤ Button n until the ›
cursor is pointing to the BACK TO MANUAL
SETUP line of the SPEAKER SIZE sub-
menu, and then pressing the Set Button p so that
the
MANUAL SETUP submenu appears. Then
press the ¤ Button n until the › cursor is point-
ing to the SPEAKER X-OVER line. Press the
Set Button p, and the SPEAKER X-OVER
submenu will appear (see Figure 13).
