System Configuration
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
menu (Figure 12).
EZSET/EQ MAIN
When the complete EQ Design process is
complete, you will be given an opportunity to
"test drive" the settings by listening to a source
with the room equalization 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 II. 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
menuscreen (Figure 13) will appear with instruc-
tions 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 ıd 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 Q when the volume is set to the prop-
er level.

The final menu screen before the EzSet/EQ
process starts is a warning screen (Figure 14)
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 systems 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 recom-
mend that you rerun EzSet/EQ II. If you do not
wish to start the test process at this time, press
Navigation Button DF to
the
⁄ / ¤
return to either the EzSet/EQ II menu or the
Master Menu, and press the OK/Enter Button
E on the TC 30 or the Set Button Q. To
begin the EzSet/EQ II Near Field measurements,

NOTE: Once the EzSet/EQ II process starts, the
volume 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/EQ II is finished.

At this point you will begin to hear a series of
test tones circulate among all the speakers in
your system. While this is happening, the
AVR 745 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 reproduction. When the test is completed
you will hear the tones stop, and the system will
pause fors long as a minute while the processor
makes its calculations. Do not be alarmed if the
"WARNING" message remains on the screen
after tones stop until a results message is dis-
1 *
played.
NOTE: While these tests detect whether a speak-
a t l e a s t
er is connected to a particular output, they can-
not determine whether the speaker is in the cor-
rect position. (For example, it can tell whether a
speaker is connected to the Surround Right out-
put, 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 as the tone circulates, matching the
name shown for each channel to the location of
the speaker. If a tone is heard from a speaker
position that does not match the on-screen mes-
sage, make a note of the incorrect speaker con-
nections. When the test process stops you will
see a message indicating the they Far Field
measurements are complete, but since there is a
connection error press the
Button DF so that the on-screen cursor in
Fig. 15 is pointing to
MAIN MENU
E on the TC 30 or the Set Button Q. At
this point, exit all menus and turn the receiver
off. Check all speaker wire connections and then
rerun EzSet/EQ II.
When the Far Field tests are complete a message
screen will appear to confirm if 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 15 on your screen. If the
speaker positions shown match the actual speak-
er layout in your system, confirm that the cursor
is pointing to

If the measurements are not successful due to a
missing or malfunctioning speaker, the
FIELD E Q ERROR
shown in Figure 16. 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
where the tests did not report back that a speak-
er is present. Should this message appear, make
note of the suspect speaker location, exit all
menus and turn the receiver off. Check all speak-
er wire connections and then rerun EzSet/EQ.
