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 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
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
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.

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
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
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 F, and the SPEAKER SETUP screen shown in Figure 13 will appear. Select Manual Configuration to view the settings resulting from EzSet/EQ. The manual Speaker Setup screens are explained in the next chapter.
