6 Unplug the earphone-type microphones.

• When unplugging the microphones, pull on the plug,

not the cord itself.

NOTES

• Do not press any buttons on the remote control or the front panel

of the receiver during Precise Surround Setup; otherwise, the

receiver stops setting and returns to the normal operation mode.

– After “COMPLETE” is displayed, the Precise Surround Setup results

are applied to the speaker settings.

• The speaker size measured by Precise Surround Setup may be

different from that of the manual setting recommendation (see

page 30). Precise Surround Setup measures the speaker size not

only by the cone speaker size but also by the other speaker features.

• There may be a case that the receiver fails to detect subwoofer

and does not activate it (no optimized test tone comes out of the

subwoofer).

In such a case, set the volume level of the subwoofer higher and

perform Precise Surround Setup again.

• When you change your listening environment, such as speakers,

speaker position, your listening position or so, perform Precise

Surround Setup again to optimize the speaker settings.

• Depending on the listening environment, Precise Surround Setup

may not measure the speaker settings accurately. In such a case,

adjust the settings manually. See pages 29 to 32.

• The supplied earphone-type microphones cannot be used as

headphones.

7 Turning the frequency optimizing function

off

After performing Precise Surround Setup, the receiver

optimizes the frequency response for each speaker.

You can turn the frequency optimizing function off.

Press PSS to turn the frequency optimizing

function off.

• Each time you press the button, the frequency optimizing

function alternates between on and off.

When the function is activated, the PSS indicator is lit.

NOTE

This function is not available:

– Until Precise Surround Setup has been completed at least once;

otherwise, “NO PSS” appears on the display.

– When selecting “A MULTI” for the audio input setting (see page 12).

– When multi-channel PCM signals (see page 41) are coming in with

selecting “HDMI” for the audio input setting (see page 12).

7 Checking the frequency responses corrected

by Precise Surround Setup

You can check the current settings of the frequency responses

with test tones from speakers and the indications on the

display when the frequency optimizing function is activated.

From the remote control ONLY:

1 Press TEST to check the frequency

response of each speaker on the display.

• A test tone also comes from each speaker in the following

order:

FL (Left front speaker) = C (Center speaker) = FR (Right

front speaker) = SR (Right surround speaker) = SBR

(Right surround back speaker)* = SBL (Left surround back

speaker)* = SL (Left surround speaker) = SW (Subwoofer)

* When using a single speaker for the surround back

speaker, the test tone comes out of “SB (Surround back

speaker)” instead of “SBR” and “SBL.”

• The frequency response of each speaker appears on the

display as follows:

EX. 1: When a test tone comes from the left front speaker

EX. 2: When a test tone comes from the subwoofer

2 Press TEST again to stop the test tone.

NOTE

While the PSS indicator is off, pressing TEST generates test tones

without showing frequency responses. See page 36.
