High Frequency Components for High Output Articulated Line Arrays

摘要

The narrow vertical pattern achieved by line arrays has prompted much interest in the method for many forms of soundreinforcement in recent years. The live sound segment of the audio community has used horns and compression driversfor sound reinforcement for several decades. To adopt a line array philosophy, to meet the demands of high level soundreinforcement, requires an approach that allows for the creation of a line source from the output of compression drivers.Additionally it is desired that the line array take on different vertical patterns dependant upon use. This requires thesolution to allow for the array to be articulated. Outlined in this work is a waveguide/compression driver combinationthat is compact and simple in approach and highly suited for articulated arrays.
