Speaker Size And Crossover - Harman Kardon AVR 445 Owner's Manual

Speaker Size Menu
Although most listeners will prefer to take advantage
of the accuracy and speed of EzSet/EQ to make all of
the necessary speaker adjustments, advanced users
may wish to experiment with how different combina-
tions of settings sound in their home theater environ-
ment or to use settings other than those calculated
by EzSet/EQ, to accommodate personal listening
preferences.
The menu system used in your AVR 445 differs
somewhat from conventional speaker setup menus in
that it consolidates the speaker "size" and crossover
into one convenient menu. Even if you are familiar with
making these adjustments, it is strongly recommended
that you read the following section of this manual.
On the SPEAKER SIZE menu (Figure 18) you
have the option to change the type of speaker config-
ured for each of the four position 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 sub-
woofer for low-frequency effects (LFE) signals, to
change the subwoofer bass redirection mode when
the Front Left/Right speakers are set to Large and to
change the setting for the subwoofer size. If, as rec-
ommended, you have first run the EzSet/EQ system,
as shown on pages 26–28, the settings established
by EzSet/EQ will be displayed as a starting point for
any manual adjustments. You may reestablish those
settings at any time during an adjustment on this menu
Navigation Button n©
by pressing the /

until the cursor is on the EZSET SETTINGS
line of the menu and then pressing the
Navigation Button n© 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 FRONT L/R, CENTER,
SIDE SURR and BACK SURR menu lines,
it is important to know the frequency range for the
speaker. This information is typically found in the
"Specifications" section of the speaker's owner's man-
ual. If you cannot find the specification for the lowest
frequency the speaker can handle, start with the set-
tings entered by running EzSet/EQ 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 manually adjust the speaker settings, go to the
SPEAKER SIZE menu by pressing the
OSD Button
MASTER MENU (Figure 1) appears, press the

is on the EZSET/EQ line and press the Set
Button pœ. Navigate to the EZSET/EQ
MANUAL SETUP line and press the Set Button
pœ. When the EZSET/EQ MANUAL
SETUP menu (Figure 17) appears, press the
Navigation Button n© again until the

cursor is on the SPEAKER SIZE line and
press the Set Button pœ.
On the SPEAKER SIZE menu (Figure 18)
you will see a display of either the settings that
were established when EzSet/EQ 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
n© to change the setting, but note that when
you do this for the first time in the menu, a warning
message (Figure 19) will appear in the on-screen dis-
play reminding you to rerun EzSet/EQ 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.

The warning message will remain for a few seconds
and then the SPEAKER SIZE menu will return
to the screen. At this point you may change the set-
tings to the "size" or crossover for any of the four
speaker positions using the Navigation Buttons
n© as shown above. The information below
details the settings 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 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 sur-
round 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 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.
