3 Select each channel in turn and adjust the distance
as necessary.
Use / to adjust the delay of the speaker you selected
to match the reference speaker. The delay is measured in
terms of speaker distance from 0’01’’ to 45’00’’.
Listen to the reference speaker and use it to measure the
target channel. From the listening position, face the two
speakers with your arms outstretched pointing at each
speaker. Try to make the two tones sound as if they are
arriving simultaneously at a position slightly in front of
you and between your arm span.

When it sounds like the delay settings are matched up,
press to confirm and continue to the next channel.
• For comparison purposes, the reference speaker will
change depending on which speaker you select.
• If you want to go back and adjust a channel, simply
use / to select it.

Standing Wave
•Default setting: ON
2
/ATT 0.0dB (all filters)
Acoustic standing waves occur when, under certain
conditions, sound waves from your speaker system
resonate mutually with sound waves reflected off the
walls in your listening area. This can have a negative
effect on the overall sound, especially at certain lower
frequencies. Depending on speaker placement, your
listening position, and ultimately the shape of your room,
it results in an overly resonant (‘boomy’) sound. The
Standing Wave Control uses filters to reduce the effect of
overly resonant sounds in your listening area. During
playback of a source, you can customize the filters used
for Standing Wave Control for each of your MCACC
presets.

1 Select ‘
Standing Wave
’ from the
Manual MCACC
setup menu.
2 Adjust the parameters for the Standing Wave
Control.
• Filter Channel – Select the channel to which you will
apply the filter(s): MAIN (all except center channel
and subwoofer), Center or SW (subwoofer).
• TRIM (only available when the filter channel above is
SW) – Adjust the subwoofer channel level (to
compensate for the difference in output post-filter).
• freq / Q / ATT – These are the filter parameters where
freq represents the frequency you will be targeting
and Q is the bandwidth (the higher the Q, the
narrower the bandwidth, or range) of the attenuation
(ATT, the amount of reduction to the targeted
frequency).

You will return to the Manual MCACC setup menu.
Acoustic Calibration EQ Adjust
• Default setting: ON
2
/0.0dB (all channels/bands)
Acoustic Calibration Equalization is a kind of room
equalizer for your speakers (excluding the subwoofer). It
works by measuring the acoustic characteristics of your
room and neutralizing the ambient characteristics that
can color the original source material (providing a ‘flat’
equalization setting). If you’re not satisfied with the
adjustment provided in Automatically setting up for
surround sound (MCACC & Full Band Phase Control) on
page 10 or Automatic MCACC (Expert) on page 44, you
can also adjust these settings manually to get a
frequency balance that suits your tastes.

Note
1 • If you can’t seem to achieve this by adjusting the distance setting, you may need to change the angle of your speakers very slightly.
• For better audibility, the subwoofer emits a continuous test tone (oscillating pulses are heard from your other speakers). Note that it may be
difficult to compare this tone with the other speakers in your setup (depending on the low frequency response of the reference speaker).
2 You can switch on or off the Standing Wave and Acoustic Calibration EQ feature in the AUDIO PARAMETER menu. See Setting the Audio
options on page 96 for more on this.
