SYSTEM CONFIGURATIONSYSTEM CONFIGURATION
SYSTEM CONFIGURATION 21SYSTEM CONFIGURATION 21
NOTE: In order to adjust the speaker settings for the
surround back channels, a Dolby Digital or DTS source
must be playing. This enables the system to activate
the surround back processing mode.
When you have completed your selections for the
main surround channels, press the
¤ Button n on
the remote to move the cursor to SURR BACK.
This line serves two functions in that it not only
configures the setting for the surround back channels
when they are present; it also tells the AVR 235’s
processing system to configure the unit for either 5.1
or 6.1/7.1 operation.
Press the
‹/› Buttons o on the remote to select
the option that best describes the speakers in use at
the left and right back surround positions based on the
definitions on this page:
When NONE is selected, the system will adjust so
that only 5.1-channel surround processing/decoding
modes are available and the surround back amplifier
channels will not be used.
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 subwoofer
output.
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 235,
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 to the AVR 235, 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 235 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 created for certain movies.
Press the
‹
/
›
Buttons o on the remote so that
SUB (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 you are listen-
ing to, 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.
When all initial speaker “size” settings have been
made, you now have the option to take advantage of
the AVR 235’s Triple Crossover system, which allows
individual crossover settings to be made for each
speaker grouping. The low-frequency crossover point
is set by the design of your speakers. Depending on
the design and driver complement of your speakers,
it is defined as the frequency below which the signal
should be redirected to the subwoofer, and is therefore
usually the lowest possible frequency the speaker is
capable of reproducing. If your main speakers include
an onboard powered woofer section intended to serve
the function of a subwoofer, the crossover point should
be set at the frequency where the loudspeaker divides
the signal between its powered woofer section and
any other drivers. 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 three groupings, front left/right, center and sur-
rounds, by looking at the specifications page of the
speakers’ 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.
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, proceed by pressing the
⁄
Button
n so that the cursor moves back up to the top of
the list of setting options. Press the
⁄
/
¤
Buttons
n so that X-OVER is highlighted and the menu
data will change to the screen shown in Figure 6.
Figure 6
To change the setting for any of the three 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 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 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-frequency “hole” where your system will have
no bass information.
In cases where LARGE has been selected as the
front channel speaker option and LFE+L/R has
been 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 SUBWOOFER crossover
point is determined by the settings for the main
speakers, and by default it will be set to match the
crossover point of the LEFT/RIGHT channels.
This ensures a smooth transition between the main
speakers and the subwoofer. You may change the
SUBWOOFER setting so that the crossover
matches the setting for the CENTER, SUR-
ROUND or SURROUND BACK channels,
depending on the capabilities of the loudspeakers
used at those locations. For example, if the crossover
setting for your center speaker is higher than the set-
ting for your main left and right speakers, you may
prefer to set the subwoofer to match the center
speaker in order to avoid losing low-frequency infor-
mation from the center channel, which is heavily used
in most movies and television programs.
When all crossover 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 lis-
teners do not need to have individualized speaker set-
