VRALB03L0700000000 is an intelligent line array with multiple functions and characteristics. It is mainly used for the stage management of small and medium size concert hall, which can meet the needs of various performance scenes. Its multiple functions and controls, especially the sound beam array time delay and sound field angle corrector, are the most distinct features of this line array.The working principle of the VRALB03L0700000000 could be divided into three parts: sound waves, sound field angle correcting and array control. Firstly, a sound wave is generated by low frequency driver, for instance, a longform sound wave with frequencies below 70 Hz. Then, sound field angle correcting is applied, which adjusts the sound field according to the reflecting surface in the concert hall. Finally, the array control parameter adjusts the amplitude of the sound waves, modifies the time delay and generates an overall array sound field.The application of the VRALB03L0700000000 is related to the acoustics of the scene. It could increase the envelope effect of the whole concert hall and lengthen the reverberation time by adjusting the time delay of the sound beam array. Also, the sound field angle corrector could do the compensation for the reflecting surfaces and detailed sound field repeating effect, creating a high-quality concert sound field and bringing much enjoyment for the audience.The greatest advantage of the VRALB03L0700000000 is that it could reduce the reverberation in the concert hall effectively while maintaining the reverberation time. By using the time-delay adjusting system and sound field angle corrector, the unwanted sound pressure and directivity graph distortions in a single frequency could be reduced. This result in a uniform sound field and effective acoustic bass control, helping to avoid feedback which could cause movement misalignment and acoustic overemphasis.Besides these applications, the VRALB03L0700000000 could also create a wide range of different sound field styles, like direct sound field, backward echo field, passive reflection effect field and other unique effects. It could combine different parameters into the programme, like initial delay, time difference and sound field envelope. Therefore, engineers and audio technicians could use this line array to create a concert sound field optimal for the scene.Overall, the sound beam array VRALB03L0700000000 is a kind of advanced sound system with line array structure control and multiple applications, which brings convenience to stage designers and enriches the performance style in small and medium size concert hall.
