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 31, and 33.
• The supplied earphone-type microphones cannot be used as
headphones.
• When the AV COMPU LINK remote control system works during
Precise Surround Setup, this receiver stops setting and returns to
the normal operation mode.

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 11).
– When multi-channel PCM signals (see page 41) are coming in with
selecting “HDMI” for the audio input setting (see page 11).

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.
