Digitally Steerable Phased Array Column Speaker

The DSP1500T features advanced directional sound control, allowing simultaneous three-axis beam adjustment to deliver focused audio coverage across designated listening areas. It incorporates eight custom-designed 4-inch transducers, each powered by an independent channel of an 8-channel amplifier. Combined with an advanced switching power supply, this configuration ensures stable operation and reliable performance.

Unlike conventional column speakers, which rely on fixed acoustic designs such as convex, concave or angled front baffles to achieve directivity, this phased array column speaker offers flexible post-installation adjustment. Through an intuitive web-based control interface, users can remotely configure vertical directivity and radiation angles to suit different room layouts and audience positions. The integrated digital equalizer further enables precise sound tuning, helping improve audio clarity and reproduction quality.

Combining precise beam steering, flexible configuration and straightforward installation, the DSP1500T is suitable for a wide range of professional sound reinforcement applications. By directing acoustic energy toward intended listening areas and reducing unnecessary reflections, it helps minimize sound energy waste while enhancing speech intelligibility in challenging acoustic environments.
