Fine Speaker Distance

• Default setting: 10.0 ft (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.

2Adjust the distance of the left channel from the listening position.

3Select 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 0.5 to 45.0 feet.

3b.Fine	SP	Distance
L		10.0ft (Reference)
R	[	9.0ft ]
C		9.5ft

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.

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).
