System Configuration
Figure 27
To change the setting for any of the four speaker
positions, press the
⁄ / ¤ Navigation Button
DF until the cursor points to the line where
you wish to make the change. Press the
‹ / ›
Navigation Button DF to change the set-
ting, 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/EQ II after 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.
Figure 28
The warning message will remain for four sec-
onds 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
DF as shown above.
The information below details the settings avail-
able 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-fre-
quency information. If your speakers at any posi-
tion 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-lim-
ited speakers that do not have the ability to
properly reproduce low-frequency sounds, select
SMALL .
At all speaker 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 com-
patible 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 out-
puts for that channel. For all speaker positions
except the front left/right, when
LARGE is cho-
sen, no derived sound will be sent to the sub-
woofer 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 fre-
quency 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 frequency
the speakers in question are capable of handling.
If one of the six available crossover points does
not match, select the one that is above, but clos-
est to, the speaker’s low-frequency limit.
When there are no speakers available at a specif-
ic 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. Note that when your 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 42 for more infor-
mation on the Dolby Virtual Speaker mode.)
Note that when NONE is selected for the Back
Surround speakers, the 6.1/7.1 channel surround
modes are not available. When 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 55 for more information on
amplifier configuration.)
Once any desired changes have been made to
the speaker size and/or crossover, press the
⁄ / ¤ Navigation Button DF to move
the cursor to any other line on this menu to make
a setting change, or go to the
BACK T O
MANUAL SETUP menu and then press the
OK/Enter Button E on the TC 30 or the Set
Button Q to continue with overall configura-
tion.
LFE Low-Pass-Filter Setting
The
LFE L P FLT line selects the frequency
setting below which sounds that may be avail-
able from a special low-frequency effects (LFE)
track are sent to the subwoofer. In most cases,
this setting will be set accurately by EzSet/EQ
but, should you wish to make a change from that
setting or the 120Hz frequency that is most com-
monly used in the creation of LFE channels by
motion picture sound mixers, after making sure
that the
SPEAKER SIZE menu (Figure 27)
is on the screen, press the ⁄ / ¤ Navigation
Button DF so that the cursor is pointing to
LFE L P FLT . Press the ‹ / › Navigation
Button DF to begin the selection process,
and note that the warning message (Figure 28)
will appear reminding you to rerun EzSet/EQ II
after all changes have been made.
When the SPEAKER SIZE menu returns to
the screen, press the ‹ / › Navigation Button
DF to make your selection. When the
desired setting appears, press the
⁄ / ¤
Navigation Button DF to move the cur-
sor to any other line on this menu where you
wish to make a setting change, or go to the
BACK T O MANUAL SETUP menu and
then press the OK/Enter Button E on the TC
30 or the Set Button Q to continue with
overall configuration.
Sub Mode Setting
When the Front Left/Right speakers are con-
figured as “Large” and a subwoofer is detected
by EzSet/EQ II or manually configured as being
available, additional options are available to furt-
her customize bass redirection. To change these
settings, first make sure that the
SPEAKER
SIZE menu (Figure 27) is on the screen, and
then press the ⁄ / ¤ Navigation Button
DF so that the cursor is pointing to SUB
MODE . Press the ‹ / › Navigation Button
DF to begin the selection process, and note
that the warning message (Figure 28) will appear
reminding you to rerun EzSet/EQ II after all
changes have been made.
The following options are available:
• The default setting for Large front left/right
speakers when a subwoofer is present is SUB
L/R + LFE . In this mode, all sounds below
the crossover point set on the LFE L P FLT
line will be sent to BOTH the subwoofer and
the front left/right speakers.
• To send only the LFE channel information to
the subwoofer, but have all other (“derived”)
low-frequency sounds sent to the front
left/right speakers, select the
SUB (LFE)
setting.
