 Hi everyone, Daniela from K-array here. Today I'm in a beautiful theater and a pop band is ready to play, but where is the PA system? Well, if you're looking for big, heavy boxes, you're not going to spot it. The PA system, in fact, is composed of only extremely discreet, four-inch wide columns, supported and driven by self-powered subwoofers. This system is actually the combination of three compact portable systems KR802 merged together to create a larger system for this large theater. From an acoustical point of view, these columns are really unique, composed of only identical, closely spaced, full-range loudspeakers. These columns show true, pure line array characteristics. They are able to cover long distances uniformly, minimizing at the same time the amount of energy sent towards the ceiling and the floor, thanks to a very high directivity in the vertical plan. But why is that? Which are the physical principles and the practical applications of a true, pure line array? Well, we have covered all these in a webinar dedicated to pure array technology in live sound. If you want to know more, I really recommend that you watch the entire webinar, which, as always, is available on our website, www.k-array.com, in the K Academy section. Our webinars are free to watch and available in multiple languages, so I hope you enjoy it and see you for the next video.
