1. Product Description
Thephased-arraycolumnspeakerisanewtypeofpublicaddress device.Byapplyingthe electronicand
digitalsignalprocessing(DSP)technologies,itcan simulatethe directivityof differentshapesof column
speakers,whilethe inherent performancesofthe phased-arraycolumnspeakerwill not beaffected, e.g.
rated power,rangeoffrequencyresponseand max. sound pressurelevel.
