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.
