• Standing Wave – Control overly resonant low
frequencies in your listening room (see Standing
Wave on
page 78).
The last two settings are specifically for customizing the
parameters explained in Acoustic Calibration EQ Adjust
on page 79:
• EQ Adjust – Manually adjust the frequency balance
of your speaker system while listening to test tones
(see Acoustic Calibration EQ Adjust on page 79).
• EQ Professional – Calibrate your system based on
the direct sound coming from the speakers and make
detailed settings according to your room’s reverb
characteristics (see Acoustic Calibration EQ
Professional on
page 79).
Fine Channel Level
• Default setting: 0.0dB (all channels)
You can achieve better surround sound by properly
adjusting the overall balance of your speaker system. You
can adjust the Channel Level of each speaker in 0.5 dB
increments. The following setting can help you make
detailed adjustments that you may not achieve using the
Manual speaker setup on
page 84.
1 Select ‘Fine Channel Level’ from the Manual
MCACC setup menu.
The volume increases to the 0.0 dB reference level.
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 (+/
–12.0 dB) 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: 10’00” (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 half inch increments. The following
setting can help you make detailed adjustments that you
may not achieve using the Manual speaker setup on
page 84.
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.
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.
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,
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 60 for more on this.
