When both the Far Field and Near Field measure-
ments have been successfully completed your
system is ready for use. Thanks to EzSet/EQ, the
settings for speaker “size”, speaker crossover,
channel output and individual channel delay time
have been automatically set and require no fur-
ther adjustment. In addition, EzSet/EQ also per-
forms a complete room equalization that tailors
the system’s performance for the best possible
sound with your combination of speakers, speak-
er placement and room acoustics. The next few
pages in this manual detail the procedure for
manually entering system data, but unless you
want to view the setting information and make
an adjustment, you are now ready to enjoy the
finest in home theater and music reproduction.
Go to page 40 for complete information on
operating your AVR.
Manual Setup
In most cases it is simpler, easier and more
accurate to let EzSet/EQ take care of entering the
system parameters for speaker “size”, speaker
crossover, channel output and individual channel
delay time. However, if you feel that your listen-
ing room or system components are best suited
to manual entry of these settings, the AVR 645
also allows you to enter or trim any of these tra-
ditional system parameters. Even if you do make
the settings manually, we recommend that you
run the EzSet/EQ tests first so that a baseline set-
ting is established, and then make your adjust-
ments from there. Note that once EzSet/EQ has
been run you do not need to adjust all system
settings, only those that you want to adjust.
To view or change the current settings, press the
OSD Button
L
on the remote to bring up the
MASTER MENU
(Figure 7). Next, press the
¤
Navigation Button
E
as needed until the
cursor is on the
EZSET/EQ
line. Navigate to
the
EZSET/EQ MANUAL SETUP
line.
Press the
Set Button
F
to view the
MANUAL SETUP
menu (Figure 18).
Figure 18
If you have already run the EzSet/EQ calibration
system, the first line of the menu enables you to
hear the difference between the settings estab-
lished by EzSet/EQ. The default setting is
O N
,
which plays the incoming source with the
EzSet/EQ settings. To hear the system in a Bypass
mode, with none of the equalization filters in the
circuit path, press the
‹
/
›
Navigation Button
E
so that
OFF
is highlighted. Note that once
changed, this setting will remain until you
change it again in this menu. While you may
want to use this menu option to hear the
difference that EzSet/EQ makes, we recommend
that you leave the setting on to take advantage
of the benefits of EzSet/EQ’s advanced room
correction technology.
The
EZSET ADJUST
line on the menu
enables you to set the system’s Tilt, or high-fre-
quency boost. To make this adjustment, first
make sure that
EZSET E Q
line is set to ON, as
this item is not available when EzSet EQ is not in
the signal path. When the cursor is on the
EZSET ADJUST
line, press the
Set Button
F
, and then press the
‹
/
›
Navigation
Button
E
to enter the desired setting. When
you have completed your adjustment, press the
›
Navigation Button
E
to move the cursor
down to the
BACK T O MANUAL SETUP
line and press the
Set Button
F
.
Note on Manual Setup Menus:
Each of the
four major manual setup menus (Speaker Size,
Speaker Crossover, Delay Adjust and Channel
Adjust) includes a line that reads
EZSET
SETTINGS
. When the default setting of
OFF
is shown you are able to make any
required adjustments that are available on that
menu. However, you may change the setting to
O N
at any time to recall the settings established
when EzSet/EQ was last run. It is also important
to note that when the EzSet/EQ settings are in
use, the AVR will not allow any changes to be
made. To trim the settings press the
‹
/
›
Navigation Button
E
until the cursor is on
the
EZSET SETTINGS
line on the menu in
use and press the
‹
/
›
Navigation Button
E
to change the setting to
OFF
. This will allow
you to make changes to the settings on that
menu.
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 adjust-
ments, advanced users may wish to experiment
with how different combinations of settings
sound in their home theater environment or to
use settings other than those calculated by
EzSet/EQ, to accommodate personal listening
preferences.
The menu system used in your AVR 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 19)
you have the option to change the type of
speaker configured 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 subwoofer 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
recommended, you have first run the EzSet/EQ
system, as shown on pages 29-32, 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 by pressing the
⁄
/
¤
Navigation Button
E
until the cursor
is on the
EZSET SETTINGS
line of the
menu and then pressing the
‹
/
›
Navigation
Button
E
so that
O N
is highlighted 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 fre-
quency below which low-frequency information
is sent to the subwoofer, 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 “Specifica-
tions” 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/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
