Beam Steering

TOA brought together its proprietary line array technology and digital signal processing (DSP) technology in developing the SR-D8 active line array speaker.

As well as processing both analog and digital audio input, this innovative speaker harnesses 8 built-in digital amplifiers to project sound waves to targeted areas with greater precision than is possible with conventional speakers. By digitally shaping the width and angle of acoustic beams, it can steer sound precisely to desired areas without requiring a change of installation location.

AM-CF1 Real-time steering array microphone

The AM-CF1 is an audio system for conference rooms which incorporating TOA’s proprietary array microphone technology,digital signal processing and 2-way active speakers. While you can see the clearer image via any video conferencing system, are you hearing conversation clearly? High quality loudspeakers, and array microphone which collects sound ideally by detecting and tracking voice in real-time will make team collaboration more productive and your presentation more attractive.

TOA brought together it s proprietary line array technology and digital signal processing (DSP) technology in developing the SR-D8 active line array speaker. As well as processing both analog and digital audio input, this innovative speaker harnesses 8 built-in digital amplifiers to project sound waves to targeted areas with greater precision than is possible with conventional speakers. By digitally shaping the width and angle of acoustic beams, it can steer sound precisely to desired areas without requiring a change of installation location.
Vertical beam width is adjustable by increments of 1° within a range of 45°, while the vertical beam steering angle is adjustable from -45° to +45° in increments of 1°. When targeting two separate areas at the same time, sufficient coverage can be achieved by splitting the beam into two direct ions and adjusting the width and vertical angle of each beam. Such beam splitting is especially effective when simultaneously covering both floor and balcony seating. By calculating the various parameters of steering settings from parameters such as speaker setting and audience setting, users can make the system automatically set the angle and width of the beam so that it goes precisely in the direction of the set audience location.
