SYSTEM CONFIGURATION SYSTEM CONFIGURATION
20 SYSTEM CONFIGURATION 20 SYSTEM CONFIGURATION
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 230,
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 230 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 frequen-
cies under frequency selected, as described
below, as well as the LFE information.
When all initial speaker “size” settings have been
made, you now have the option to take advantage of
the AVR 230’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 which is either the lowest
possible frequency the speaker is capable of repro-
ducing, or the frequency at which sound is sent to the
speaker’s internal low-frequency driver, as opposed to
the mid-range driver. 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 each
speakers’ 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, should you wish to change one
of the settings, please 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. Note, also, that when the
LARGE-
LFE+L/R setting has been selected, the
crossover point is set by making adjustments at the
SUBWOOFER line, but the setting for the front
left/right speakers will automatically change in tandem
so that the same setting appears for both speaker
positions. This ensures that there is no “hole” in the
sound field due to different crossover points at the
front and subwoofer speakers.
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 con-
figuration, crossover settings and output levels 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 listeners 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 dif-
ferent crossover points 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.
If you wish to customize the speaker settings and out-
put levels 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 procedure for any input where you
wish to have a different set of speaker configuration
and crossover settings.
When all speaker selections have been made, press
the
¤ Button n and then the Set Button p to
return to the MASTER MENU.
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.
The AVR 230’s advanced software enables you to
quickly and easily set delay times without the need to
calculate them using a complex formula. Instead, all
you need to do is measure the approximate distance
between your listening position and each of the
speakers in your system. When you enter those
distances into the AVR’s memory as shown below,
the AVR’s microprocessor does the rest of the work,
calculating the proper delay time. The measurements
need not be accurate to the inch, as the system is
designed to accommodate a typical listening area
rather than require the precise measurement to one
“sweet spot” position.
Due to the differences in the way each surround
mode operates, some modes allow for a greater range
of delay times than others. To avoid problems, we
recommend that delay times be adjusted using the
Dolby Digital mode. If a different mode is selected at
a later time, the AVR 230 will automatically restrict
the delay settings to those required by the surround
mode in use.
