Harman-Kardon AVR 445 - Manual (Page 32)

32 SYSTEM CONFIGURATION
System Configuration
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
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 out-
puts 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 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
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. 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 37 for more information 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 47 for more information on
amplifier configuration.)
Once any desired changes have been made to
the speaker size and/or crossover, press the
⁄ / ¤ Navigation Button E 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
Set Button F to continue with overall
configuration.
LFE Low-Pass-Filter Setting
The
LFE L P FLT line selects the frequency
setting below which sounds that may be
available 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 commonly used in the creation of LFE
channels by motion picture sound mixers, after
making sure that the
SPEAKER SIZE menu
(Figure 19) is on the screen, press the ⁄ / ¤
Navigation Button E so that the cursor is
pointing to LFE L P FLT . Press the ‹ / ›
Navigation Button E to begin the selection
process, and note that the warning message
(Figure 20) will appear reminding you to rerun
EzSet/EQ after all changes have been made.
When the SPEAKER SIZE menu returns to
the screen, press the ‹ / › Navigation Button
E to make your selection. When the desired
setting appears, press the
⁄ / ¤ Navigation
Button E to move the cursor 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 Set Button
F 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 or manually configured as being
available, additional options are available to
further customize bass redirection. To change
these settings, first make sure that the
SPEAKER SIZE menu (Figure 19) is on the
screen, and then press the ⁄ / ¤ Navigation
Button E so that the cursor is pointing to
SUB MODE . Press the ‹ / › Navigation
Button E to begin the selection process, and
note that the warning message (Figure 20) will
appear reminding you to rerun EzSet/EQ 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.
• To have low-frequency information sent to the
subwoofer only when Large speakers are
selected, choose
SUB (L/R) . This option is
only available when the unit is set to
SURROUND OFF so that a pure analog
audio path is provided.
• When no subwoofer is present and Large
speakers are configured for the front left/right
position, select
NONE . This will route all low-
frequency information to the front left/right
speakers.
When the SPEAKER SIZE menu returns to
the screen, replacing the warning message, press
the
‹ / › Navigation Button E to make your
selection. When the desired setting appears,
press the
⁄ / ¤ Navigation Button E to
move the cursor 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 Set Button F to continue
with overall configuration.
Subwoofer Size
The final setting on the
SPEAKER SIZE
menu enables you to change the setting for the
subwoofer size. In the event that EzSet/EQ did
not accurately enter the correct size, or if you
wish to experiment with a different setting, first
make sure that the
SPEAKER SIZE menu
(Figure 19) is on the screen; then press the ⁄ / ¤
Navigation Button E so that the cursor is
pointing to SUB SIZE and then press the ‹ / ›
Navigation Button E to begin the selection
process. Note that a warning message will
appear for 4 seconds to remind you to rerun
EzSet/EQ after all changes have been made.
Select a setting that best matches the diameter
of your subwoofer’s driver, or which provides the
appropriate high-pass filter setting for your sys-
tem. In each case, the frequency of the high-pass
filter determines the frequencies below which no
information is sent to the subwoofer:
• The setting for an 8-inch/200mm driver
activates a 38Hz subwoofer high-pass filter.
• The setting for a 10-inch/250mm driver
activates a 30Hz subwoofer high-pass filter.
• The setting for a 12-inch/305mm driver
activates a 20Hz subwoofer high-pass filter.
• The setting for a 15-inch/380mm driver
activates a 15Hz subwoofer high-pass filter.
When all changes to Speaker-related settings
have been made, press the
⁄ / ¤ Navigation
Button E until the cursor is on the BACK
T O MANUAL SETUP menu and then
pressing the Set Button F so that you may
make any other adjustments to the system
parameters. It is also important to remember to
rerun the EzSet/EQ system if any changes have
been made to the settings on this menu,
following the instructions shown on page 30 for
using the Manual mode.
The Speaker Configuration may also be changed
at any time without using the full-OSD on-screen
menu system by pressing the Speaker Selector
6 on the front panel or
b on the remote
control. Once the button is pressed, FRONT
