If at any time the test tone is not heard from the
speaker indicated on screen, press the Set
Button F to stop EzSet/EQ. Turn off the AVR
using the Main Power Switch 1 and check
your speaker connections. Make sure all wires
are connected to the correct speakers and
Speaker Outputs DEFO on the AVR, and
that you have observed the correct polarity
(+ terminals connected to + terminals and
– terminals connected to – terminals).
NOTE: While this test detects whether a
speaker is connected to a particular output, it
cannot determine 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 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
message, stop EzSet/EQ, exit the menus, turn
your receiver off and check for proper speaker
connections on the rear panel before resuming
the setup.
If EzSet/EQ detects only one speaker in a pair
(e.g., surround back left but no surround back
right or no main speakers), it will generate an
error and stop, displaying a screen similar to
Figure 19. If that happens, check that you have
placed your speakers in their correct locations,
and that you have wired each speaker to its
correct set of speaker terminals.

• Speaker Distance: This test will circulate the
tones again as the name of each channel is
shown to measure the distance from the
microphone to each speaker. The results of
these tests will be used to set the delay time
settings for each active speaker position.
During the Speaker Distance test a screen
similar to the one shown in Figure 20 will
appear. The speaker position will change as
EzSet/EQ measures the distance for each
speaker.

• Speaker Size: The measurements and
calculations for this test take place at the same
time as the test signals are circulated to
calculate the output levels, and they are used to
determine whether the speakers in your system
are "large" or "small" for the purposes of bass
management. (If desired, you may use the
results of the automated testing as a baseline
and then make manual adjustments to the
speaker size settings on a source-independent
basis, following the instructions shown on page
29.)
During the Speaker Size test a screen similar to
the one shown in Figure 21 will appear, with the
speaker position changing as each speaker is
measured.
Figure 21
At the same time the overall size of the
speaker's frequency range is measured, the AVR
will measure the crossover setting for each
speaker in your system to create a seamless
transition between the frequencies sent to your
main speakers and subwoofer (if available). If
desired, you may use the results of the
automated testing as a baseline and then make
manual adjustments to the crossover settings on
a source-independent basis, following the
instructions shown on page 29.
NOTE: The crossover determined by EzSet/EQ is
not the same as the crossover frequency
specification that appears in the speaker's
manual. EzSet/EQ is measuring the point at
which the audio signal must be passed from the
main speaker to the subwoofer. For an individual
loudspeaker, the manufacturer specifies the
point or points at which the audio signal is
passed from one transducer within the speaker
to another.
• Room Equalization: Each room has unique
characteristics that may affect the frequency
response at the listening position. For
example, doorways and alcoves can increase
bass response nearby. Varying surfaces such as
hard floors or windows, or soft carpets or
draperies, may also affect the way the room
responds to sound. Until now, expensive
testing devices and long hours of taking
measurements and adjusting room furnishings
were required in order to smooth out the
frequency response to avoid artifacts. EzSet/EQ
simplifies equalization, delivering world-class
performance without the extra expense. While
the test tone circulates, EzSet/EQ is able to
obtain a sonic "view" of the room and its
characteristics, and adjust the receiver's output
accordingly to customize performance to the
listening room.
While EzSet/EQ is making these adjustments a
screen similar to the one shown in Figure 22 will
appear. You may hear EzSet/EQ repeat tones
from various speakers a number of times as it
performs the equalization.

Step 8: When all measurements are
successfully completed, a screen similar to the
one in Figure 23 will appear. You may press the
Set Button F, and the
SPEAKER
screen shown in Figure 13 will appear.
