DSP1501 Phased Array Column Speaker adopts electronic and digital processing technology (DSP) to adjust the main beam radiation direction. Unlike the conventional one, DSP1501 phased array column speaker provides flexible adjustment of column directivity (vertical radiation angle) on a web-based operation page; The built-in digital equalizer can improve sound quality effectively. As it is defined by good sound quality, high performance, easy operation and installation, it is widely used in a variety of sound reinforcement occasions.
