Fine Speaker Distance
• Default setting:
3.0 m
(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
Manual speaker setup
below.
1
Select ‘Fine SP Distance’ from the Manual MCACC
setup menu.
2
Adjust the distance of the left channel from the
listening position.
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
0.1
to
9.0
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.
1
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 Manual MCACC setup menu.
Standing Wave
• Default setting:
ON
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

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).
