2 Adjust the level of the left channel.
This will be the reference speaker level, so you may want
to keep the level around
0.0dB so that you’ll have plenty
of room to adjust the other speaker levels.
• After pressing ENTER, test tones will be output.
3 Select each channel in turn and adjust the levels
(+/–10dB) as necessary.
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.
4 When you’re finished, press RETURN.
You will return to the Manual MCACC setup menu.
Fine Speaker Distance
• Default setting: 3.00 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. You can adjust the distance of
each speaker in 1 cm increments. The following setting
can help you make detailed adjustments that you may
not achieve using the
Manual speaker setup on page 52.
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
0.01 m to 9.00 m.
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.
4 When you’re finished, press RETURN.
You will return to the Manual MCACC setup menu.
Fine-adjusting the positions of the speakers
(Precision Distance)
Before using this function, perform the Auto MCACC
Setup procedure (see page 11). The auto MCACC speaker
distance correction function corrects the distance to the
speakers with a precision of 1 cm. Here, rather than
correct the numerical value of the distance, actually
move the physical positions of the speakers to fine-adjust
(the subwoofer cannot be adjusted). The input from the
microphone is indicated on the screen. Fine-adjust the
positions of the speakers so that the gauge reading is
maximum. The detailed distance adjustments that were
previously performed by skilled installers by ear can
easily be performed watching the gauge on the monitor.

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).
