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 

0.01m

 to 

9.00m

.

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.

When you’re finished, press RETURN.

You will return to the

Standing Wave

• Default  setting: 

ON

/

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.

Select  ‘Standing Wave’ from the Manual 

MCACC setup menu.

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).

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 68 for more on this.

3 • Since they will be overwritten, you may want to save the standing wave settings made with the Auto MCACC Setup 

to another MCACC preset.

• Standing Wave control filter settings cannot be changed during playback of sources using the HDMI connection.

• When 

Standing Wave

 is selected for an MCACC preset memory where 

STAND.WAVE

 is set to 

OFF

 in the 

AUDIO 

PARAMETER

, 

STAND.WAVE

ON

 is automatically selected.
