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.
I
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.
I
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 set-
tings to the receiver’s memory and return to the
MASTER MENU,
make sure that YES appears at the SAVE SETTINGS line, press
the

Navigation Button F so that the on-screen cursor is
pointing to RETURN TO MAIN MENU and press the
Set
Button H
.
NOTE: If you wish to check the test results before exiting the
EzSet/EQ menu, press the
‹

›
Navigation Buttons F so that
the on-screen cursor is at the second line of the menu listings, and
then press the
‹

Navigation Buttons F 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 3-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.
SPEAKER SETUP
This menu tells the AVR21EN which type of speakers are in use. This
is important, as it adjusts the settings that decide whether your
system will use the “5-channel” or “6-channel/7-channel” mode,
as well as determining which speakers receive low-frequency (bass)
information.
For each of these settings, use the LARGE setting if the speakers
for a particular position are traditional full-range loudspeakers.
Use the SMALL setting for smaller, frequency-limited satellite
speakers that do not reproduce sounds below 200Hz. Note that
when “small” speakers are used, a subwoofer is required to repro-
duce low-frequency sounds. Remember that the “large” and
“small” descriptions do not refer to the actual physical size of the
speakers, but to their ability to reproduce low-frequency sounds.
If you are in doubt as to which category describes your speakers,
consult the specifications in the speakers’ owner’s manual.
This menu screen also allows you to enter the settings for the
AVR21EN’s Quadruple Crossover feature, which allows a different
crossover point to be used for the front left/right, center, surround
and surround back speakers. In systems where full-range or tower
speakers are used for the front soundstage or where different
brands or models are in use at the various speaker positions,
this feature allows you to customize the bass management and
redirection circuits with a precision not previously possible.
It is easiest to enter the proper settings for the speaker setup
through the
SPEAKERS menu (
Figure 47). If that menu is not
already on screen from prior adjustments, bring up the MAIN
MENU, and then press the
