The volume increases to the 

 

 reference level.

 

This will be the reference speaker level, so you may want 
to keep the level around 

 

 so that you’ll have plenty of 

room to adjust the other speaker levels.

• After pressing 

 

, test tones will be output.

 

Use 

 

/

 

 to adjust the volume of the speaker you 

selected to match the reference speaker. When it sounds 
like both tones are the same volume, 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.

 

You will return to the Manual MCACC setup menu.

 

• Default setting: 

 

 (all speakers)

For proper sound depth and separation with your system, 
it is necessary to add a slight bit of delay to some 
speakers so that all sounds will arrive at the listening 
position at the same time. The following setting can help 
you make detailed adjustments that you may not achieve 
using the 

 

 below.

 

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 

 

 to 

 

 meters.

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.

 

You will return to the Manual MCACC setup menu.

 

• Default setting: 

 

 

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 

 

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).
