DSP1502 New 150W Array Digitally Steerable Speakers

Features

● Directivity adjustment in 3 directions;
● An active column with built-in digital power amplifier;
● Compatible with 3 common line signal inputs and 1 fixed voltage amplifier power signal input (70V ±10V);
● Built-in volume, balanced processing adjustment;
● Wire/wireless beam directivity modulation control via a Web controller;

  • Introduction
  • Specification
  • Connection

The phased-array steerable column speaker is with a 70v/100v transformer built in. The 70v/100v transmission is realized in a high-voltage, low-current mode, which makes longer distance transmission and parallel connection of multiple loudspeakers possible. By applying the electronic and digital signal processing (DSP) technologies, it can simulate the directivity from different shapes of sound columns, while the inherent performances of the sound column will not be affected, e.g. rated power, range of effective frequency response and max sound pressure level.

With DSP technologies, we can operate with the remote controller to change the directivity of speaker system at some extent. This linear array is suitable for loud speaking in a hall where the building acoustics is poor (especially long reverberation time). This phased array speaker is most suitable for the hardware (sound box, DSP processor) of the loudspeaker system in sports venues (where the volume is large, the building acoustics is poor, the reverberation time is long and the sound is muddy), so that it can be combined with special software to make the controllable sound cover useful area (auditoria, etc) correctly and prevent it from diffusion to useless area (e.g. ceiling, door or window). In this case, it can reduce the investment in acoustic decorations in venues and decrease the energy loss caused by loudspeaker system. This leads to reduced investment in both the acoustic decorations and sound system in the sports venue.
