SYSTEM CONFIGURATION

expensive test equipment and time consuming proce-

dures. The end result is a system calibration profile

that enables your new receiver to deliver the best pos-

sible sound no matter what type of speakers you have

or what the properties of your listening room are.

We recommend that you take advantage of the preci-

sion 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 30–35.

Before starting the EzSet/EQ process, make certain

that you have connected all speakers for your system

and that you have both the EzSet/EQ microphone and

the extender rod handy. If you have a standard camera

tripod, attach the extender rod to the tripod, and then

screw the microphone to the top of the rod. Place the

tripod at your primary listening position, at least three

feet from the nearest hard surface and adjust it so that

microphone is at or above ear level. If you do not

have a tripod, simply screw the extender rod into the

bottom of the EzSet/EQ microphone.

Next, plug the microphone into the

You are now ready to start the EzSet/EQ process by

following these steps:

Step 1.

Navigate to the

EZSET/EQMAIN

menu (Fig. 9) by first pressing the

OSD Button

until the

cursor is pointing to

EZSET/EQ

in the

MASTERMENU

. Press

the

Set Button

p

œ

to bring the new menu to

the screen.

Figure 9

Step 2.

Select one of the two options shown based

on the way you wish to have the system settings

entered:

• In most cases, you will want to use the Automatic

mode, which calibrates the system for speaker pres-

ence, speaker “size”, speaker crossover, channel

output level, speaker-to-listener delay time and

room equalization. To choose this mode simply

press the

Set Button

p

œ

, as the cursor is

already pointing to

AUTOMATIC EQ

DESIGN

when the menu appears on the

screen. Then press the

Set Button

p

œ

again

when the

AUTOMATICEZSET/EQ

menu appears, to continue to Step 3.

•

If you wish to enter the speaker size or crossover

frequencies

yourself, but want to have the EzSet/EQ

system test for and calibrate all the other functions

listed above, press the

to point the cursor to

and then press the

Set Button

p

œ

.

Once the

MANUALSETUP

menu (Fig. 18)

appears, follow the instructions on page 30 to

enter your desired settings for the speaker size

or Crossover Frequencies, and then return to the

EZSET/EQMAIN

menu. Press the

again so that the

cursor is pointing to

MANUALEQDESIGN

and then press the

Set Button

p

œ

. When the

interim message screen appears to remind you

to set the crossovers, make sure that the cursor

is pointing to

CONTINUE

and press the

Set Button

p

œ

again since you have

already set the crossovers.

Step 3.

The

FARFIELDMEASURE

screen

(Figure 10) will appear with instructions to place the

microphone, if you have not already done so. This

screen is also the place to set the master volume

level. As noted on the screen, use the

Volume

Control

˙

to adjust the volume level to

–35dB, as shown on the line that appears at the

bottom of the menu when the volume is adjusted.

Press the

Set Button

p

œ

when the volume is

set to the proper level.

Step 4.

The final menu screen before the EzSet/EQ

process starts is a warning screen (Figure 11) that

serves as a reminder to keep the room as quiet as

possible while the system is in use. Extraneous noise

of any kind may adversely affect the accuracy of the

system’s results. Do not talk while the test tones are

circulating, and if possible, turn off any ventilation sys-

tems if the noise form the air flow is loud enough for

you to hear. Should an outside noise such as a phone

ringing occur during the test process, we recommend

that you rerun EzSet/EQ. If you do not wish to start

the test process at this time, press the

NOTE:

Once the EzSet/EQ process starts, the volume

control and Standby/Off switches are temporarily dis-

abled while the tests are in progress. Do not adjust the

volume or turn the unit off until you see the on-screen

message change to indicate that EzSet/EQ is finished.

Step 5.

At this point, a series of test tones will circu-

late among all the speakers in your system. While this

is happening, the AVR 645 is reading the signal to

determine which speaker positions are active, what

type of speaker is present at each active position,

what the distance is from the listening position to each

speaker, and to begin to build a pro

file of the impact of

the room’s acoustics on the quality

of audio reproduc-

tion. When the tones stop, the system will pause for as

long as a minute while the processor makes its calcu-

lations based on the results of the signal measure-

ments. Do not be alarmed if the “WARNING” message

remains on the screen after tones stop until a results

message is displayed, as shown in Step 6 or 7.

NOTE:

While these tests detect whether a speaker is

connected to a particular output, they cannot deter-

mine 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 carefully to make sure that the test

tone circulates in a clockwise rotation, starting with the

front left speaker, to the center, to the front right, and

so on to the subwoofer. If the tone is heard from a

speaker that seems as though it is out of sequence,

such as the tone coming from the surround left speaker

when the next speaker in the sequence should be the

surround right speaker, exit the EzSet/EQ system when

the test sequence is completed and use the manual

output level tone adjustment process, as outlined on

page 33, to determine which, if any, speaker is incor-

rectly connected.

When the test process stops, you will see a message

indicating that the Far Field measurements are

complete. If there is an error, follow the instructions

in Step 7A or Step 7b.
