If at any time the test tone is not heard from the
speaker indicated on screen, press the Set
Button to stop EzSet/EQ. Turn off the AVR
using the Master Power Switch 1 and check
your speaker connections. Make sure all wires
are connected to the correct speakers and
Speaker Outputs 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 sim-
ilar 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 calcula-
tions 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 manage-
ment. (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 31.)
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 speak-
er'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 31.
NOTE: The crossover determined by EzSet/EQ is
not the same as the crossover frequency specifi-
cation 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 loud-
speaker, 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 exam-
ple, 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 equaliza-
tion, delivering world-class performance with-
out the extra expense. While the test tone cir-
culates, 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 successful-
ly completed, a screen similar to the one in
Figure 23 will appear. You may press the Set
Button , and the
