System Configuration

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 presence, speaker “size”, speaker

crossover, channel output level, speaker-to-

listener delay time and room equalization. To

choose this mode simply press the Set Button

, as the cursor is already pointing to

AUTOMATIC EQ DESIGN when the

menu appears on the screen.

Then press the Set Button

again when the

AUTOMATIC EZSET/EQ menu appears,

to continue to Step 3.

• If you wish to enter the speaker crossover

frequencies yourself, but want to have the

EzSet/EQ system test for and calibrate all the

other functions listed above, press the

Navigation Button

to point the cursor

EZSET/EQ SETUP and then press the

Set Button

. Once the MANUAL

SETUP

menu (Fig. 18) appears, follow the

instructions on page 32 to enter your desired

settings for the Crossover Frequencies, and

then return to the

EZSET/EQ MAIN

menu. Press the

Navigation Button

again so that the cursor is pointing to

MANUAL EQDESIGN and then press the

Set Button

. When the interim message

screen appears to remind you to set the

crossovers, make sure that the cursor is point-

ing to

CONTINUE and press the Set

Button

again since you have already set

the crossovers.

Step 3. The

FAR FIELD MEASURE

screen (Figure 17b) 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 vol-

ume 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

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 17c) 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 ventila-

tion systems 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

⁄

Navigation Button

to return to either the EzSet/EQ menu or the

Master Menu, and press the Set Button

.To

begin the EzSet/EQ Near Field measurements,

press the

‹

›

Navigation Button

so that

ONis highlighted in reverse video, and press the

Set Button

NOTE: Once the EzSet/EQ process starts, the

volume control and Standby/Off switches are

temporarily disabled 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 you will begin to hear a

series of test tones circulate among all the

speakers in your system. While this is happening,

the AVR 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 profile of the

impact of the room’s acoustics on the quality of

audio reproduction. When the test is completed

you will hear the tones stop, and the system will

pause fors long as a minute while the processor

makes its calculations. 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, below.

NOTE: While these tests detect whether a

speaker is connected to a particular output, they

cannot determine 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 as the tone circulates, matching the

name shown for each channel to the location of

the speaker. If a tone is heard from a speaker

position that does not match the on-screen

message, make a note of the incorrect speaker

connections. When the test process stops you will

see a message indicating the they Far Field

measurements are complete, but since there is a

connection error press the

Navigation

Button

so that the on-screen cursor in

Fig. 7 is pointing to

RETURN TOMASTER

and press the Set Button

. At this

point, exit all menus and turn the receiver off.

Check all speaker wire connections and then

rerun EzSet/EQ.

Step 6. When the Far Field tests are complete a

message screen will appear to confirm if the pro-

cedure was successful or not. In most cases there

will not be any problems and you will see the

message shown in Figure 17d on your screen. If

the speaker positions shown match the actual

speaker layout in your system, press the Set

Button

to complete EzSet/EQ by performing

the Near Field Measurements. Continue the

EzSet/EQ process by pressing the Set Button

to take the Near Field measurements from

the front left, center and right speakers. By taking

this separate set of measurements, the AVR is

able to complete its view of the room’s sonic

signature and apply equalization as needed to

correct spikes and dips in the system’s response.

Continue these instructions with Step 8.
