Harman Kardon AVR 7300 Owner's Manual page 27

When NONE is selected, the system will adjust so
that only 5.1-channel modes are available. When this
is the case for your system, you may wish to use the
surround back amplifier channels to power a second
set of speakers whose source is selected by the
AVR 7300's multiroom system. See page 39.
When SMALL is selected, the system will adjust so
that the full complement of 6.1/7.1 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 channels.
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 sig-
nal will be sent to the surround back channels, with no
low-frequency information sent to the subwoofer output.
When you have completed your selection for the
surround back channels, press the ¤ Navigation
Button o to move the cursor to SUBWOOFER.

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 7300,

NONE appears. With this option, all bass infor-
mation will be routed to the front left/right "main"
speakers.
• If a subwoofer is connected to the AVR 7300, you
have the option to have the front left/right main
speakers reproduce bass frequencies at all times,
and have the subwoofer operate only when the
AVR 7300 is being used with a digital source that
contains a dedicated low-frequency effects, or
LFE, soundtrack. This allows you to use both your
main and subwoofer speakers to take advantage
of the special bass sounds created for some

SUB (LFE) appears.
• 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 you are listen-

ing to, press the /

until SUB L/R+LFE appears. When this
option is selected, a full-range signal will be sent
to the front left/right "main" speakers, and the sub-
woofer will receive LFE information and the bass
frequencies under the selected crossover point.
When all initial speaker "size" settings have been
made, you now have the option to take advantage of
the AVR 7300's Quadruple Crossover system, which
allows individual crossover settings to be made for
each speaker group. The low-frequency crossover
point is the frequency below which the signal will be
redirected to the subwoofer and is set 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 repro-
ducing.
Before making any changes to the settings for
the crossover point, we suggest that you find the
crossover point for the speakers in each of the four
groupings, front left/right, center front, surround and
surround back, by looking at the specifications page
of each speaker's owner's manual, by getting that
information from the manufacturer's Web site, or
by contacting your dealer or the manufacturer's
customer service department. You will need this figure
to accurately configure the next group of settings.
Note that when any speaker group other than the front
left/right speakers is set to LARGE, the crossover
may not be adjusted, as the feed will be full-range,
with no sound being derived for the subwoofer from
that position.
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, should you wish to change
one of the settings, please proceed by pressing the
Navigation Button o so that the cursor
⁄
moves back up to the MODE line. Press the
Navigation Button o so that X-OVER
appears and the menu data will change to the
screen shown in Figure 8.

SYSTEM CONFIGURATION SYSTEM CONFIGURATION
wish to make a change and then press the
Navigation Button o until the desired setting
appears. The available choices for low-frequency
information to be sent to the subwoofer, rather than
to the main speaker channel, are 40Hz, 60Hz, 80Hz,
100Hz, 120Hz 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 to
avoid the creation of a low-frequency "hole" where
your system will have no bass information.
The setting for the crossover point for the LFE chan-
nel, which is created to provide specific low-frequency
information in many movies with digital 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
recommend that you select the speaker group whose
crossover point is closest to 120Hz. To do this, press
the / Navigation Button o until the cursor
⁄ ¤
is next to the LFE line, and then press the
Navigation Button o until the name of the
speaker group with the desired crossover frequency
appears. Of course, you may also experiment with
different settings to find the one that provides the
smoothest and most complete bass response in your
particular listening environment.
When all crossover settings have been made, or in
those cases where none are needed, press the
Navigation Button o 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 con-
figuration and crossover settings for all inputs, or to
have different settings for each input. In most cases,
the factory default setting of GLOBAL will be
appropriate, as most systems do not need individual
/ speaker settings. However, when full-range front

speakers are used for both movies and music, differ-
ent bass management settings may 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.
To customize the speaker-size configurations to each
input, make certain that the MODE line of the
SPEAKER SETUP menu is set to SIZE,
and that the cursor is on the BASS MGR line.

the settings for the next input. Repeat the procedure
