24 SYSTEM CONFIGURATION

The AVR 340 is one of the first receivers in its
class to offer automated speaker setup and sys-
tem calibration. This process greatly simplifies the
installation of your new receiver by using a series
of test signals and the power of an advanced dig-
ital signal processing system to eliminate the
need for manual adjustment of speaker “size”,
crossover, delay and output level settings, while
adding the power of a multi-band parametric
equalizer to smooth out any peculiarities in fre-
quency response that may result from the charac-
teristics of the listening room. With EzSet/EQ your
new receiver even alerts you to errors in speaker
connections that prevent a speaker from function-
ing.

With EzSet/EQ you are able to calibrate your sys-
tem in a fraction of the time it would take to
enter the settings manually, and with results that
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 con-
figuration settings manually, or trim the settings
provided by EzSet/EQ by following the instruc-
tions on pages 26 through 32.

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 26 through 32.

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 340’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 

⁄

/

¤

D to move

the on-screen cursor to the 

EZSET/EQ

menu

line. Press the Set Button

F to move to the

next screen (Figure 7).

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 Set Button

F.

If you do not wish to continue with the EzSet/EQ
process, press the 

‹

/

›

E and then press the Set Button F to
return to the 

MASTER MENU

. Note that if you

attempt to move to the next menu without plug-
ging 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 perform
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 7).

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 26 through 32.

Step 7: The 

WARNING

screen will automati-

cally be replaced by the main EzSet/EQ menu
(Figure 7). 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 full complement of

seven main speakers (front left/center/front
right/surround right/surround back right/sur-
round back left/surround left) and a subwoofer,
press the 

‹

/

›

E

so that 

7.1

appears to the right of

MEASUREMENT

, and then press the Set

F to start EzSet/EQ.

• If your system includes a traditional surround

speaker complement of five main speakers
(front left/center/ front right/surround right/sur-
round left) and a subwoofer, press the 

‹

/

›

E so that 

5.1

appears to the right of 

MEASUREMENT

,

and then press the Set Button

F to start

EzSet/EQ. To stop the calibration process at any
time, press the 

⁄

/

¤

D to move the on-screen cursors to the

MEASUREMENT

line; press the 

‹

/

›

E so that 

STOP

appears and press the Set Button

F.

Step 8: Once EzSet/EQ has been started, you will
hear test signals circulate among all of the speak-
ers 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 cal-
ibration 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 pro-
ceeds, you will see the following messages as the
individual measurements are taken:
