When a conventional column speaker needs to change the main beam radiation direction (Audible direction), the column mounting angle (tilt) must be mechanically adjusted. Phased Array Column Speaker is the one that adjusts the main beam radiation direction with electronic and digital processing technology (DSP). It can change its radiation direction under the condition of fixed vertical installation of the column speaker, overcoming the shortcomings of traditional column speaker installation such as unattractive appearance and difficulty of free adjustment.
DSP1500T, with excellent directivity, can adjust three directions simultaneously, so that listeners in the direction can get excellent listening experience. Eight customized 4-inch speakers are driven by a 8-channel amplifier powered with a sophisticated switch, all of which combine to ensure years of reliable operation. For conventional column speakers, its directivity is to be done with different shapes such as convex, concave, and bevel through processing, and cannot be adjusted. Unlike the conventional one, the DSP1500T 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. With good sound quality, high performance, easy to use, easy to install and other characteristics, it is widely used in a variety of sound reinforcement occasions, effectively reducing sound energy loss while improving language clarity.
The DSP1500T column speaker uses our dedicated web phase-control adjustment controller operation to achieve excellent directivity adjustment through the built-in excellent phase-control beam adjustment algorithm.
