• Speaker Crossover: The measurements and calculations for this test take place at the same
time as the test signal is circulated to calculate the levels, and they are used to determine 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, following the instructions described in:
Speaker Setup/Crossovers . When
this test is complete, a crossover frequency will be shown to the right of the
SPEAKER X-OVER
line on the menu screen.
• 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. Various 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.
Step 9: When all measurements are successfully completed, the test signals will stop and a TEST
DONE UNPLUG MIC
message will appear in the second line. The cursor will pause at
SAVE
SETTINGS
, allowing you the option of selecting
YES
or
NO
. Unplug the microphone and store it in
a safe place so that it is available to recalibrate your system if needed due to a change in
speakers, preferred listening position, or a major change in the room’s furnishings (such as the
addition of thick carpeting or plush furniture) that might require different settings. To enter the
settings to the receiver’s memory and return to the Master Menu, make sure that
YES
appears at
the
SAVE SETTINGS
line , press the ▼ / ▲ Navigation Buttons [oval 16] so that the on-screen
cursor is pointing to
RETURN TO MAIN MENU
and press the Set Button [oval 18] .
NOTE: If you wish to check the test results before exiting the EzSet/EQ menu, press the ◄ / ►
Navigation Buttons [oval 16] so that the on-screen cursor is at the second line of the menu
listings, and then press the ◄ / ► Navigation Buttons [oval 16] to scroll through the list of
speaker positions. The data on each line will also be entered into the listings on the individual
SPEAKER SETUP , DELAY ADJUST and CHANNEL ADJUST menus once you exit EzSet/EQ.
If the tests to any of those three channel pairs indicates that one, but not
both
of the speakers in
the pair is present, the menu will show NONE next to the speaker position where the tests did not
report back that a speaker is present. Should this message appear, make note of the suspect
speaker location, exit all menus and turn the receiver off. Check all speaker wire connections and
then rerun EzSet/EQ.
When you have successfully completed the EzSet/EQ process and made any needed
adjustments to the input and surround mode configurations, your receiver is ready for use. If you
do not wish to make any manual adjustments to the settings, you may skip the rest of this section
and proceed to
the Main Room Operation section of this manual to learn how to operate the
AVR21EN, although we recommend that you first record your system’s settings using the
worksheets in the
Appendix , in case the settings need to be reentered due to a power loss or for
some other reason. For those situations where you may wish to make a change to the settings
entered by EzSet/EQ, follow the instructions on the following pages.
Output Level Adjustment
Output level adjustment is a key part of the configuration of any surround sound product. It is
particularly important for a digital receiver such as the AVR21EN, as correct outputs ensure that
you hear soundtracks with the proper directionality and intensity.
