• With error messages (such as Ambient Noise or

Microphone Check) select RETRY after checking for

ambient noise (see Problems when using the Auto

MCACC Setup on page 9) and verifying the mic

connection. If there doesn't seem to be a problem,

you can simply select OK and continue.

If necessary, confirm the speaker configuration in

the OSD.

The configuration shown on-screen should reflect the

actual speakers you have.

If you see an error message (ERR) in the right side

column (or the speaker configuration displayed isn't

correct), there may be a problem with the speaker

connection. If selecting RETRY doesn't work, turn off the

power and check the speaker connections. If there

doesn't seem to be a problem, you can simply use

to select the speaker and

(and number for surround back) and continue.

Make sure 'OK' is selected, then press ENTER .

A progress report is displayed on-screen while the

receiver outputs more test tones to determine the

optimum receiver settings for channel level, speaker

distance, and Acoustic Calibration EQ.

Again, try to be as quiet as possible while this is

happening. It may take 2–6 minutes.

• If you selected a Multi-Point setup (in step 3), you

will be asked to place the mic at the 2nd and 3rd

reference points before finally placing it at your main

listening position.

Note

1 This screen is only shown if you selected ALL or Speaker Setting in Auto Mode from the Auto MCACC Option menu.

2 • Depending on the characteristics of your room, sometimes identical speakers with cone sizes of around 12 cm will end up with different size settings.

You can correct the setting manually using the Manual speaker setup on page 44.

• The subwoofer distance setting may be farther than the actual distance from the listening position. This setting should be accurate (taking delay and

room characteristics into account) and generally does not need to be changed.

3 Since the distance measurements have been set according to the sound characteristics of your speakers, there are cases where (for optimal surround

sound) the actual distance may differ from the speaker distance setting.

you've connected (see page 45 for more on this)

• Channel Level – The overall balance of your speaker

system (see page 45 for more on this)

• Speaker Distance – The distance of your speakers

from the listening position (see page 46 for more on

this)

• Standing Wave – Filter settings to control lower

'boomy' frequencies (see page 39 for more on this)

• Acoustic Cal EQ – Adjustments to the frequency

balance of your speaker system based on the

acoustic characteristics of your room (see page 40

for more on this)

Press ENTER after you have finished checking each

screen. When you're finished, select RETURN to go back
