  • Introduction
  • Specification

When a conventional digitally steerable 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.

DSP1501, with excellent sense of direction, can adjust three directions simultaneously, so that listeners in the direction can get excellent listening experience. Ten customized 4-inch speakers are driven by a 10-channel amplifier powered with a sophisticated switch, all of which combine to ensure years of reliable operation. For conventional column speakers, its sense of direction is to be done with different shapes such as convex, concave, and bevel through processing, and cannot be adjusted. Unlike the conventional one, the DSP1501 phased array column speaker provides flexible adjustment of column sense of direction (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 DSP1501 unit uses our dedicated web phase-control adjustment controller to achieve excellent sense of direction adjustment through the built-in excellent phase-control beam adjustment algorithm.
