Using Delay to Correct Time Alignment Problems

Problem:

Some larger sound systems may utilize loudspeaker fill systems. One loudspeaker

may not be enough for a large hall because of power limitations. A fill loudspeaker may be placed

farther in front of the main speaker to augment the sound from the main loudspeaker. This may cause

the sound from the fill loudspeaker to arrive at the listener earlier than that from the main loudspeaker.

To the audience, it will seem like the sound is coming from the wrong place when the sound from the fill

loudspeaker arrives first.

Solution:

The delay in the DFR11EQ can be used to solve this problem. Place a DFR11EQ in

the audio path to the amplifier of the fill loudspeaker, then set it to the proper amount of delay by

following the

Setting Delay by Distance

instructions. If the proper amount of delay is used, the sound

from both loudspeakers will arrive at the audience at the same time. Now, the audience will perceive

the sound coming from the correct place.
