SYSTEM CONFIGURATION
expensive test equipment and time consuming proce-
dures. The end result is a system calibration profile
that enables your new receiver to deliver the best pos-
sible sound no matter what type of speakers you have
or what the properties of your listening room are.
We recommend that you take advantage of the preci-
sion of EzSet/EQ to calibrate your system, but if
desired you may also make any of the configuration
settings manually, or trim the settings provided by
EzSet/EQ by following the instructions on pages 30–35.
Before starting the EzSet/EQ process, make certain
that you have connected all speakers for your system
and that you have both the EzSet/EQ microphone and
the extender rod handy. If you have a standard camera
tripod, attach the extender rod to the tripod, and then
screw the microphone to the top of the rod. Place the
tripod at your primary listening position, at least three
feet from the nearest hard surface and adjust it so that
microphone is at or above ear level. If you do not
have a tripod, simply screw the extender rod into the
bottom of the EzSet/EQ microphone.
Next, plug the microphone into the EzSet/EQ
Microphone Jack J located behind the Front
Panel Control Door 9.
You are now ready to start the EzSet/EQ process by
following these steps:
Step 1. Navigate to the EZSET/EQ MAIN
menu (Fig. 9) by first pressing the OSD Button
∫ on the remote. Press the
¤
Button n© until the
cursor is pointing to
EZSET/EQ in the MASTER MENU. Press
the Set Button pœ to bring the new menu to
the screen.

Step 2. Select one of the two options shown based
on the way you wish to have the system settings
entered:
• In most cases, you will want to use the Automatic
mode, which calibrates the system for speaker pres-
ence, speaker "size", speaker crossover, channel
output level, speaker-to-listener delay time and
room equalization. To choose this mode simply
press the Set Button pœ, as the cursor is
already pointing to AUTOMATIC EQ
DESIGN when the menu appears on the
screen. Then press the Set Button pœ again
28 28 SYSTEM CONFIGURATION SYSTEM CONFIGURATION
when the AUTOMATIC EZSET/EQ
menu appears, to continue to Step 3.
• If you wish to enter the speaker size or crossover
frequencies yourself, but want to have the EzSet/EQ
system test for and calibrate all the other functions
listed above, press the
n© to point the cursor to EZSET/EQ
SETUP and then press the Set Button pœ.
Once the MANUAL SETUP menu (Fig. 18)
appears, follow the instructions on page 30 to
enter your desired settings for the speaker size
or Crossover Frequencies, and then return to the
EZSET/EQ MAIN menu. Press the
Navigation Button n© again so that the
¤
cursor is pointing to MANUAL EQ DESIGN
and then press the Set Button pœ. When the
interim message screen appears to remind you
to set the crossovers, make sure that the cursor
is pointing to CONTINUE and press the
Set Button pœ again since you have
already set the crossovers.
Step 3. The FAR FIELD MEASURE screen
(Figure 10) will appear with instructions to place the
microphone, if you have not already done so. This
screen is also the place to set the master volume
level. As noted on the screen, use the Volume
Control )r˙ to adjust the volume level to
–35dB, as shown on the line that appears at the
bottom of the menu when the volume is adjusted.
Press the Set Button pœ when the volume is
Navigation
set to the proper level.

Step 4. The final menu screen before the EzSet/EQ
process starts is a warning screen (Figure 11) that
serves as a reminder to keep the room as quiet as
possible while the system is in use. Extraneous noise
of any kind may adversely affect the accuracy of the
system's results. Do not talk while the test tones are
circulating, and if possible, turn off any ventilation sys-
tems if the noise form the air flow is loud enough for
you to hear. Should an outside noise such as a phone
ringing occur during the test process, we recommend
that you rerun EzSet/EQ. If you do not wish to start
the test process at this time, press the
Navigation Button n© to return to either the
EzSet/EQ menu or the Master Menu, and press the
Set Button pœ. To begin the EzSet/EQ Near
Navigation Button

NOTE: Once the EzSet/EQ process starts, the volume
control and Standby/Off switches are temporarily dis-
abled while the tests are in progress. Do not adjust the
volume or turn the unit off until you see the on-screen
message change to indicate that EzSet/EQ is finished.

Step 5. At this point, a series of test tones will circu-
late among all the speakers in your system. While this
is happening, the AVR 645 is reading the signal to
determine which speaker positions are active, what
type of speaker is present at each active position,
what the distance is from the listening position to each
speaker, and to begin to build a profile of the impact of
the room's acoustics on the quality of audio reproduc-
tion. When the tones stop, the system will pause for as
long as a minute while the processor makes its calcu-
lations based on the results of the signal measure-
ments. Do not be alarmed if the "WARNING" message
remains on the screen after tones stop until a results
message is displayed, as shown in Step 6 or 7.
NOTE: While these tests detect whether a speaker is
connected to a particular output, they cannot deter-
mine whether the speaker is in the correct position.
(For example, it can tell whether a speaker is connected
to the Surround Right output, but it cannot tell whether
the speaker is on the right or left side of your listening
room.) For that reason, we strongly recommend that
you try to listen carefully to make sure that the test
tone circulates in a clockwise rotation, starting with the
front left speaker, to the center, to the front right, and
so on to the subwoofer. If the tone is heard from a
speaker that seems as though it is out of sequence,
such as the tone coming from the surround left speaker
when the next speaker in the sequence should be the
surround right speaker, exit the EzSet/EQ system when
the test sequence is completed and use the manual
output level tone adjustment process, as outlined on
page 33, to determine which, if any, speaker is incor-
rectly connected.
When the test process stops, you will see a message
indicating that the Far Field measurements are
complete. If there is an error, follow the instructions
in Step 7A or Step 7b.
