ence, speaker "size", speaker crossover, channel
output level, speaker-to-listener delay time and
room equalization. To choose this mode, simply
press the OK/Enter Button E on the TC 30 or
the Set Button œ, as the cursor is already point-
ing to Automatic when the menu appears on the
screen. Then press the OK/Enter Button E on
the TC 30 or the Set Button œ again when the
AUTOMATIC EZSet/EQII menu
appears, and continue to Step 1 of the EQ Design
process.
• If you wish to set the speaker size and crossover,
channel delay or channel output levels manually and
then have EzSet/EQII set the room equalization, with
the EZSET/EQ MAIN menu (Figure 12) on
the screen, press the / Navigation Buttons
⁄ ¤
D© to move the cursor to the EZSET/EQ
MANUAL SETUP line and then press the
OK/Enter Button E on the TC 30 or the Set
Button œ on the ZR 10 remote. Follow the
instructions on pages 33 to 38 for the items you
wish to set manually. During that process, a mes-
sage may appear reminding you to run EzSet/EQ,
which you may ignore at this time since you will
return to the EzSet/EQ menu at the conclusion of
your manual adjustments.
After completing all manual settings, press the
Navigation Buttons D© to move

the cursor to the BACK TO EZSET/EQ
MAIN line and then press the OK/Enter Button
E on the TC 30 or the Set Button œ on
the ZR 10 remote. When that menu (Figure 12)
returns to the screen, press the /
⁄
Buttons D© again to move the cursor to the
MANUAL EQ DESIGN line and then press
the OK/Enter Button E on the TC 30 or the
Set Button œ on the ZR 10 remote. A message
will appear, reminding you to manually set the sys-
tem parameters, but since you have just done that,
make certain that the cursor is at the CONTIN-
UE line and press the OK/Enter Button E on
the TC 30 or the Set Button œ on the ZR 10
remote. Follow the steps shown below to complete
the EzSet Design process.
• If you wish to enter the settings for speaker configu-
ration, channel output adjustment and delay times
manually, press the / Navigation Buttons
⁄ ¤
D© to move the cursor to the EZET/EQ
MANUAL SETUP line and then press the
OK/Enter Button E on the TC 30 or the Set
Button œ on the ZR 10 remote. This will take
you to the MANUAL SETUP menu, where
additional submenus contain the configuration
adjustments. Skip to page 33 for details on
manual setup.
• The EZSET/EQ PRESET SELECT

line is used to recall one of the three EQ Designs
that may be stored with different settings. For more
information on using the Preset Selections, see
page 38 or 48.
EQ Design is done in a series of steps, with the Far
Field measurements first, followed by the Near Field
measurements and, finally, the Subwoofer measure-
ments. In each case, the process is the same: the
on-screen menus will direct you to place the micro-
phone in a specific location, and when that portion of
the process is started, test tones will be sent to the
speaker or speakers being measured. The system will
then pause slightly as the results of the measurement
are calculated and stored in system memory.
If the step was successful, an on-screen message will
report the test results and direct you to the next step.
If the step did not produce acceptable results, an error
message will appear, suggesting the adjustments
needed to correct the problem and start a re-test.
During each EQ Design step, you have the option
to perform the tests for that specific portion of the
process, or you may skip the settings and move to
another step or return to the EZSET/EQ
MAIN menu (Figure 12).
When the complete EQ Design process is complete,
you will be given an opportunity to "test drive" the set-
tings by listening to a source with the room equaliza-
tion filters applied. In order to take advantage of this
feature, before beginning the EQ Design, make certain
that a source is playing with program material you are
familiar with. If necessary, exit the menu system at this
time to select and start the playback, and then return
to EzSet/EQ. The source will mute during the EQ

Design, but will return when it is time for the "test
drive."
Step 1. The EZSET DESIGN STEP 1
menu (Figure 13) will appear with instructions as to
where to place the microphone. As noted on the
screen, use the Volume Control )r to adjust
the volume level to –25dB, as shown on the line that
appears at the bottom of the menu when the volume
is adjusted. Press the OK/Enter Button E on the
TC 30 or the Set Button œ when the volume is
set to the proper level.

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 systems if the noise from the airflow 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/EQII. To begin the
EzSet/EQII Far Field measurements, press the
Navigation Buttons D© so that ON is high-
lighted in reverse video, and press the OK/Enter
Button E on the TC 30, or the Set Button œ.
NOTE: Once the EzSet/EQII process starts, the vol-
ume control and Standby/Off switches are temporarily
disabled 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/EQII
is finished.
At this point, a series of test tones will circulate among
all the speakers in your system. While this is happen-
ing, the AVR 745 is reading the signal to determine
which speaker positions are active, what type of
speaker is present at each active position and 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.
