Step 8: Once EzSet/EQ has been started, you will hear test signals circulate among all of the
speakers as the system sets the master volume level, checks for the presence of speakers, sets
the distance measurement and calculates delay time settings, sets the output level for each
speaker, sets the speaker “size”, and sets the speaker crossover point, and automatically
equalizes the frequency response to eliminate any artifacts or reverberation that may occur due
to the specific room characteristics, such as alcoves and doorways. During the measurement and
calibration process, you may observe the progress of the testing by reading the messages that
appear in the second line of the menu listing. When the EzSet/EQ screen first appears, it contains
a series of dashes, but as the test and measurement proceeds, you will see the following
messages as the individual measurements are taken:
• System Level: A
SETTING LEVEL
message will appear to indicate that the system is setting
the overall volume level to the proper level as a prelude to testing the individual channels.
During this test, you will see this line of the menu screen change as the volume level is
adjusted.
• Speaker Check: The system will circulate a test signal to determine which channels have a
speaker connected. During this test, you will see the name of each channel position displayed
while a signal is sent to that speaker.
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. When this test is complete,
YES
will
be shown to the right of SPEAKER CHECK on the menu screen.
• Speaker Delay: 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. When this test is complete,
a speaker-to microphone (listening position) distance will be shown to the right of the
SPEAKER
DELAY
line on the menu screen.
NOTE: A/V Sync Delay may only be set manually (See section: AVR21EN Configuration/Lip
Sync ).
• Speaker Level: This test circulates a test signal and measures the output from each active
speaker position. The results of the measurements are used to adjust the individual channel
outputs as needed, so that they are identical. This is an essential element of ensuring that
surround sound fields are properly reproduced. If desired, you may use the results of the
automated testing as a baseline and then make manual adjustments to trim the output levels to
your personal taste, following the instructions described in:
Main Room Operation/Output
Level Trim Adjustment . When this test is complete, an output level adjustment number will be
shown to the right of the
SPEAKER LEVEL
line on the menu screen.
• 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 make manual adjustments to the speaker size settings,
following the instructions described in
: Speaker Setup/Speaker Configuration and Bass
Management .) When this test is complete, an output level adjustment number will be shown to
the right of the
SPEAKER SIZE
line on the menu screen.
