SYSTEM CONFIGURATION 21
ENGLISH
System Configuration
rival those achieved with expensive test equip-
ment and time-consuming procedures. The end
result is a system calibration profile that enables
your new receiver to deliver the best possible
sound, no matter what type of speakers you have
or what the dimensions of your listening room
are.
We recommend that you take advantage of the
precision of EzSet/EQ to calibrate your system,
but if desired you may also make any of the
configuration settings manually, or trim the
settings provided by EzSet/EQ by following the
instructions on pages 23 through 27.
If you wish to configure your AVR manually, or if
for some reason your EzSet/EQ microphone is
unavailable, you may still do so by following the
instructions on pages 23 through 27.
Step 1: EzSet/EQ requires that your listening
room have as little background noise as possible
to avoid interfering with the measurement of
tones produced by your AVR during the setup
procedure. Turn off all loud fans, air conditioners
and other equipment, and try to avoid making
any noise during the process.
Step 2: The EzSet/EQ microphone should be
placed in either your usual listening position or, if
there is a large seating area, the center of the
room, at the listeners’ ear level. You may find it
convenient to use a camera tripod for stable
placement of the EzSet/EQ microphone at the
correct height. The microphone includes a thread-
ed insert on the bottom for tripod mounting.
Step 3: Plug the EzSet/EQ microphone into the
AVR 147’s Headphone Jack
4, making certain
that the mini-plug to 1/4" phone plug adaptor
supplied with the microphone is firmly connected.
The microphone cable is approximately 7 meter
long, which should accommodate most listening
room situations. If required, you may use an
optional extension cable, available at most elec-
tronics stores, for use in larger rooms. However,
we recommend that you avoid using extension
cords for the microphone cable, as they may
adversely affect the test results.
Step 4: Once the microphone is properly posi-
tioned and plugged in, proceed to the EzSet/EQ
menus by first pressing the OSD Button
L to
bring the Master Menu to the screen. Next, press
the
⁄ / ¤ Navigation Buttons D to move
the on-screen cursor to the EZSET /EQ menu
line. Press the OK Button F to move to the
next screen (Figure 5a).
Step 5: The first screen of the EzSet/EQ system
will now appear to remind you to plug in the
microphone. If you have not already done so,
plug the microphone into the Headphone Jack
4 as described in steps 2 and 3. When you are
ready to proceed, make certain that the cursor is
pointing to
YES and press the OK Button F.
If you do not wish to continue with the EzSet+
process, press the
‹ / › Navigation Buttons
Ea for the arrow to point to NO and then
press the OK Button
F to return to the
MASTER MENU . Note that if you attempt to
move to the next menu without plugging in the
microphone, a reminder message will flash at the
bottom of the screen.

Step 6: After entering YES to start the
EzSet/EQ system, you will next see a brief warn-
ing message, and the screen will then change to
the main EzSet/EQ menu. The
WARNING screen
is a reminder that in order for the system to per-
form accurate measurements, it is important that
the listening room be as quiet as possible.
After 5 seconds, the screen will change again to
display the main EzSet/EQ menu (Figure 5b).

IMPORTANT NOTE: Anyone with hearing that is
sensitive to loud noises should leave the room at
this point, or use ear protection sufficient to
reduce the noise level. Inexpensive foam-style ear
plugs, available at most drug stores, may be used
to reduce the sound level to a tolerable level. If
you are uncomfortable with, or cannot tolerate,
loud sounds and do not use some sort of ear pro-
tection, we strongly recommend that you leave
the room and ask someone else to run the
EzSet/EQ process, or that you do not use
EzSet/EQ and enter the configuration settings
manually, as described on pages 23 through 27.
Step 7: The WARNING screen will automati-
cally be replaced by the main EzSet/EQ menu
(Figure 5c).

While this screen is visible, you may start and
stop the calibration process, or monitor the
progress of the measurements and view the
results. When the screen first appears, you will
see
MEASUREMENT: STOP on the first line
of the menu list. To start the EzSet/EQ test
process, you must first tell the system how many
speakers are in your system. To do that, choose
one of these two options:
• If your system includes a traditional surround
speaker complement of five main speakers
(front left/center/ front right/surround right/
surround left) and a subwoofer, press the
‹ / ›
Navigation Buttons Ea so that 5.1
appears to the right of MEASUREMENT ,
and then press the OK Button F to start
EzSet/EQ. To stop the calibration process at any
time, press the
⁄ / ¤ Navigation Buttons
D to move the on-screen cursors to the
MEASUREMENT line; press the ‹ / ›
Navigation Buttons Ea so that
STOP
appears and press the OK Button F.

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 level,
checks to see where there are speakers, sets the
distance measurement and calculates delay time
settings, sets the speaker “size”, and sets the
speaker crossover point. 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:
