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. 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.

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 to 9.00 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.
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 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 a MCACC preset memory where S-WAVE is set to OFF in the Audio parameter, S-WAVE ON is automatically
selected.

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
0.0dB
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
3
presets.
1 Select 'Standing Wave' from the Manual MCACC
setup menu.

2 Select 'ON' (if it is not already selected) then adjust
the parameters for the Standing Wave Control.
• Filter Ch – 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).
• f / Q / ATT – These are the filter parameters where f
represents the frequency you will be targeting and Q
is the bandwidth (the higher the Q, the narrower the
bandwidth, or range) of the attenuation (ATT, the
amount of reduction to the targeted frequency).
