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 445 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 31, 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.
Step 6. When the Far Field tests are complete, a
message screen will appear to indicate whether the
procedure was successful or not. In most cases, there
will not be any problems and you will see the mes-
sage shown in Figure 11 on your screen.

If the speaker positions shown match the actual
speaker layout in your system, confirm that the cursor
is pointing to DO NEAR FIELD and press the
Set Button pœ to take the Near Field measure-
ments from the front left, center and right speakers.
Continue these instructions with Step 8.
Step 7a. If the measurements are not successful due
to a missing or malfunctioning speaker, the FAR
FIELD EQ ERROR message will appear as
shown in Figure 12. EzSet/EQ is programmed to look
for speaker pairs at the front left/front right, surround
left/surround right and surround back left/surround
back right positions. If the test results indicate that one,
but not both of the speakers in any of these pairs is
present, the menu will show NO next to the speaker
position where the tests did not report back that a
speaker is present. Should this message appear, make
note of the suspect speaker location, exit the menus
and turn the receiver off. Check all speaker wire con-
nections and then rerun EzSet/EQ.

Step 7b. In some cases, the system may not function
properly, due to overly high output levels. When this
occurs, you will see the message shown in Figure 13.
If you see this message, verify that the microphone is
in the correct position, and is not too close to any one
speaker. Then press the Set Button pœ to go
back to the MASTER MENU. From there, return
to the EzSet/EQ system and when you are once again
at the FAR FIELD MEASURE screen,
reduce the system volume level by 3dB before trying
EzSet/EQ again.

Step 8. When the Far Field measurements are com-
pleted, the next step is to take three Near Field meas-
urements, one at each front speaker position. These
measurements enable EzSet/EQ to produce the most
accurate settings for high-frequency equalization. The
Near Field measurements are similar to the Far Field
tests, except that the system will "listen" to only one
speaker at a time, rather than sending the test signals
to all speakers in rotation.
At the NEAR FIELD EQ SELECT menu
(Figure 14) that should be on your screen after com-
pleting the instructions in Step 6, press the Set
Button pœ to start the near field measure-
ments with the front left speaker. If you are repeating
the setup process, you may also use the
Navigation Buttons n© to select any of the
three speaker positions shown.

At the NEAR FIELD MESSAGE menu,
you will see an instruction to place the microphone
in a different position than the one used for the initial
Far Field measurements. This time, place the micro-
phone close to the speaker to be measured, at a
distance of about 2 feet. The top of the microphone
should be pointed toward the speaker, rather than
pointing up as was done for the Far Field tests.
Press the Set Button pœ to continue.
Step 9. You will now see a WARNING message
similar to the one shown in Figure 10 except that it will
contain an option to return to the NEAR FIELD
EQ SELECT menu (Figure 14) as well as the
ability to return to the MASTER MENU. If you
are ready to proceed with the test, make certain
that the microphone is properly pointed toward the
speaker selected for calibration, at a distance of about
Navigation Button n©
2 feet. Press the ›
