SYSTEM CONFIGURATION

SYSTEM CONFIGURATION 23

Press the

‹

›

Buttons

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 525,

press the

‹

›

Buttons

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 525, 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 525 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

‹

›

Buttons

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

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 525’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 front and

surrounds by looking at the specifications page of the
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.

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

so that the cursor moves back up to the

top of the list of setting options. Press the

⁄

Buttons

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

until the cursor

is next to the line where you wish to make a change
and then press the

‹

›

Buttons

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 a 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

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 listeners do not need to have
individualized speaker settings. However, some listen-
ers, particularly those with full-range front speakers
that are used for both movies and music may prefer
that different 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 crossovers to each input,
make certain that the cursor is on the

BASS MGR

line and press the

‹

›

Buttons

so that

INDIVIDUAL

appears in highlighted video.

When this setting is entered by exiting the menu, the
configuration settings just entered will apply to the
current input ONLY, and you will need to go back to
the

IN/OUT

menu to select another input, and

then return to this menu page again to change the
settings for the next 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

and then the

Set Button

return to the

MASTER

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 525’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 dis-
tances into the AVR’s memory as shown below, the
AVR’s microprocessor does the rest of the work, cal-
culating 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.
