FIE exe MN d Problem Illustration A Some larger sound systems may utilize loudspeaker fill systems One loudspeaker may not be enough for a large hall because of power limitations so 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 Illustration B The delay in the DP11EQ can be used to solve this problem Place a DP11EQ along the audio path to the amplifier of the fill loudspeaker then set it to the proper amount of delay The DP11EQ with Delay will hold that audio signal in memory releasingitto the fill loudspeaker only whenitis in time with the sound from the main loudspeaker so 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 Delay for Solving Phase Cancellation Problems gt C ede aus FIER e 19 6 zn DP11EQ AMPLIFIER
