the Pass Thru XLR to subwoofer will need to be slightly delayed to make up for its closer position to
the audience.
•
Time Alignment Basics:
•
To compensate for different distances’, determine the speaker farthest from the audience and delay
other speakers with the same signal to “time align” with the speaker farthest away from the audience.
•
Sound travels through air at average humidity and room temperature at about 1.1 feet per ms.
Measure the difference in distance of each speaker feeding the audience. Feed the speaker farthest
from the audience with no time alignment delay. Set delays for the other closer speakers based on
their distance ahead of the farthest back speaker. Measure the distance difference and enter 1 ms
per 1.1 feet that each speaker is ahead of the farthest back speaker in your configuration. Time
alignment is not perfect as not all audience positions measure the same speaker distance differences.
•
The EON718S offers 50ms of speaker delay on it’s input stage.
•
Polarity – This inverts the polarity of the subwoofer. OFF indicates the woofer is in standard polarity. ON means
the polarity of the subwoofer is reversed.
