28 SYSTEM CONFIGURATION

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 (identical with the one for the surround
speakers) will be sent to the subwoofer output
when the subwoofer is set to ON, or to the Front
LEFT/RIGHT when subwoofer is set to OFF.

When 

LARGE

is selected the system will adjust

so that the full complement of 6.1/7.1 surround
processing/decoding modes are available, and a
full-range signal will be sent to the surround
back channels, with no low-frequency informa-
tion sent to the subwoofer output.

7. When you have completed your selection for
the surround channels, press the 

¤

D

on the remote to move the cursor to

SUBWOOFER

.

8. Press the 

‹

/

›

E 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 speak-
ers, particularly 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, press

the 

‹

/

›

E on the remote so

that 

NONE

appears in the on-screen menu.

When this option is selected, all bass informa-
tion will be routed to the front left/right
“main” speakers.

• If a subwoofer is connected to the AVR, 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 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 sub-
woofer speakers to take advantage of the spe-
cial bass created for certain movies. To select
that option press the 

‹

/

›

E 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
you are listening to, press the 

‹

/

›

E on the remote so that 

L/R+LFE

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. The
subwoofer will receive the front left and right
bass frequencies under the crossover frequency
selected in another setting on this menu, as
described below, and also the LFE soundtrack.

9. When all initial speaker “size” settings have been
made, you now have the option to take advantage
of the AVR’s Quadruple Crossover system, which
allows individual crossover settings to be made for
each speaker group. In systems where full-range
or tower speakers are used for the front sound-
stage or where different brands or models are in
use at the various speaker positions, this feature
allows you to custom tailor the bass manage-
ment and redirection circuits with a precision not
previously possible.

If you have already run EzSet/EQ the settings cal-
culated during that procedure will already appear.
No further adjustment is required unless you wish
to conform a specific item to your personal taste
or a nonstandard system configuration.

The low-frequency crossover point is set by the
design of your speakers. It is defined as the frequen-
cy which is the lowest possible frequency the speak-
er is capable of reproducing. 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 manu-
facturer’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 chan-
nels, then no adjustments are needed and you may
skip this section. However, should you wish to
change one of the settings, please proceed to the

SPEAKER X-OVER

submenu, as shown in

Figure 12.

To change the setting for any of the four speaker
groups Left/Right, Center, Surround or Surround
Back, press the 

⁄

/

¤

D until the

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

‹

/

›

E until the desired setting appears. The
available choices at which point low-frequency
information will be sent to the subwoofer (or to
the Front Left/Right speakers in case subwoofer
is set to OFF), rather than to the speaker channel,
are 40Hz, 60Hz, 80Hz, 100Hz, 120Hz, 150Hz
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 lowfrequency limit 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

L/R+LFE

has been selected as the

subwoofer option, the front channel sound
information below the crossover point selected
for the L/R front speakers (when fronts are set to
"Small") will be sent to BOTH the front channel
speakers and the subwoofer.

The crossover settings for the Left/Right, Center,
Surround and Surround Back speakers are used
to determine where bass information is sent
when it is derived from the main channels of a
source. The setting for the menu line shown as

LFE

is used to impose a low-pass filter point

for the information in the Low Frequency Effects
(LFE) channel that is a part of Dolby Digital- and
DTS-encoded source material. While the LFE
channel, which is the “.1” you see in surround
sound designations, is restricted to low fre-quen-
cy sounds, some mixes may include information
that is higher in frequency than your subwoofer
is capable of reproducing. To prevent unwanted
sounds from being sent to subwoofers that can-
not handle them and which do not have a built-
in low-pass filter, the 

LFE

option line enables

you to select a setting for the low-pass filter that
is part of the subwoofer feed from the LFE chan-
nel. The settings available are the same as those
tied to any one of the four available speaker
positions on this submenu. We recommend that
you use the frequency that is just slightly higher
than the upper capability limit of your subwoofer,
as shown in the sub’s Owner’s Manual. When the
cursor is on the 

LFE

line, press the 

‹

/

›

E to choose the appro-

priate setting.

Note that the crossover point for the surround
speakers and the surround back speakers will be
identical. That´s why no crossover point for the
surround back speakers is selectable or shown in
the menu.
