SYSTEM CONFIGURATION
On the SPEAKER SIZE/X-OVER menu
(Figure 27), you have the option to change the type of
speaker configured for each of the four speaker posi-
tion groups, to change the crossover setting for any
one of those speakers, to adjust the setting point for
the low-pass filter that determines which frequencies
are sent to the subwoofer for low-frequency effects
(LFE) signals, to change the subwoofer bass redirec-
tion mode when the Front Left/Right speakers are set
to Large and to change the setting for the subwoofer
size. If, as recommended, you have first run the
EzSet/EQII system, the settings established by
EzSet/EQII will be displayed as a starting point for any
manual adjustments. You may reestablish those set-
tings at any time during an adjustment on this menu
Navigation Buttons D©
by pressing the /

until the cursor is on the EZSET SETTINGS
line of the menu and then pressing the
Navigation Buttons D© so that ON is high-
lighted in reverse video. Note, however, that once this
is done, any manual adjustments made will be lost
and must be reentered.
Speaker Size
At each of the four speaker group positions, you have
the ability to select the speaker "size" and, when a
"Small" speaker is selected, the frequency below
which low-frequency information is sent to the sub-
woofer, as opposed to the speakers for the channel
being adjusted. For that reason, before making
the adjustments on the FL/FR, CENTER,
SL/SR and SBL/SBR menu lines, it is impor-
tant to know the frequency range for the speaker. This
information is typically found in the "Specifications"
section of the speaker's owner's manual. If you cannot
find the specification for the lowest frequency the
speaker can handle, start with the settings entered by
running EzSet/EQII and then try one setting above or
below the existing entry. We do not recommend
changing the crossover point more than that, due to
the possible impact that will have on the speaker's
performance. If you do not have access to the owner's
manual for a particular speaker, you should be able
to obtain the needed information from the Web site
or customer service department of the speaker's
manufacturer.
To view or change the current speaker size settings,
make certain that the EZSET/EQ MAIN
menu (Figure 12) is on the screen. Press the
Navigation Buttons D© to move the cursor
next to SPEAKER SIZE and then press
the OK/Enter Button E on the TC 30 or the
Set Button œ on the ZR 10 remote control. The
SPEAKER SIZE menu (Figure 27) will
appear on the screen.

On the SPEAKER SIZE menu (Figure 27),
you will see a display of either the settings that
were established when EzSet/EQII was run, or the
factory default settings if you have not yet run
the automated system.
To change the setting for any of the four speaker posi-
tions, press the

until the cursor points to the line where you wish to
make the change. Press the
Buttons D© to change the setting, but note that
when you do this for the first time in the menu, a
warning message (Figure 28) will appear in the on-
screen display, reminding you to rerun EzSet/EQII
when you are finished with any speaker configuration
changes. This is necessary to make any level output
adjustments needed after the setting changes, so that
the new configuration will be properly integrated.

The warning message will remain for five seconds and
then the SPEAKER SIZE menu will return to
the screen. At this point you may change the settings
to the "size" or crossover for any of the four speaker
positions using the Navigation Buttons D© as
shown above. The information below details the set-
tings available for each of the speaker configurations.
At each of the four speaker position lines, you have
the option to set the speaker size and crossover. Note
that the "size" does not refer to the speaker's actual
/

physical size, but rather to the ability of the speaker to
reproduce low-frequency information. If your speakers
at any position are traditional full-range models
capable of handling the full audio spectrum, select
LARGE. These speakers are called "large" since
the low-frequency drivers required to play bass without
strain or distortion are typically eight to fifteen inches
in diameter, in turn making the speaker cabinet larger
than those with small (or no) low-frequency drivers.
When the speakers at a particular position are smaller

frequency-limited speakers without the ability to properly
reproduce low-frequency sounds, select SMALL.
At all positions except for the front left/right speakers,
you may also select NONE. This setting tells the
system that no speakers are present at that position,
allowing the AVR to select the correct surround modes
that are compatible with the number of speakers
installed. For example, in order to use the Dolby Digital
EX, Dolby Pro Logic IIx, DTS-ES,Logic 7/7-channel and
"7 Stereo" modes, you must have either LARGE or
SMALL speakers entered as the setting for the
BACK SURR channels.
When LARGE is selected for any channel, a full-
range signal will be sent to the speaker outputs for
that channel. For all speaker positions except the front
left/right, when LARGE is chosen, no derived
sound will be sent to the subwoofer output, although
in all cases the special low-frequency effects (LFE)
signals available on 5.1 or 6.1 digital programs will
always be sent to the subwoofer output.
When SMALL is selected for any channel, you may
also enter a setting for the crossover frequency at
which sound is divided between the frequency above
which sound is sent to the channel's speakers and
below which sound is sent to the subwoofer. When
configuring a "small" speaker, choose the setting that
has the frequency closest to that of the lowest fre-
quency the speakers in question are capable of han-
dling. If one of the six available crossover points does
not match, select the one that is above, but closest to,
the speaker's low-frequency limit.
When there are no speakers available at a specific
position, select NONE. When this option is chosen
for the Center or Side Surround speakers, the sound
that would normally be sent to these channels will be
split between the front left and right speakers. When a
system does not include Center or Surround speakers,
the use of Dolby Virtual Speaker as a surround mode
may provide a sound field that simulates the presence
of these speakers. (See page 41 for more information
on the Dolby Virtual Speaker mode.)
When NONE is selected for the Back Surround
speakers, the 6.1/7.1-channel surround modes are
not available. If this is the case for your system, you
may wish to take advantage of the availability of the
unused amplifier channel pair to power a second set
of speakers in another room. (See page 51 for more
information on amplifier configuration.)
Once any desired changes have been made to the
speaker size and/or crossover, press the
Navigation Buttons D© to move the cursor to
any other line in this menu to make a setting change,
or go to the BACK TO MANUAL SETUP
menu and then press the OK/Enter Button E on
the TC 30 or the Set Button œ to continue with
overall configuration.
