Description
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 may operate from the remote controller to change the directivity of speaker system at some extent.
This is suitable for loud speaking in a hall where the building acoustics is poor, especially for the hardware 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).
