(1) Video processor
The processing speed of the video processor decides the smooth and seamless splicing of HD image, and the simple and easy to use powerful console ensures that the image on the stage is closely connected with the plot.
(2) Broadcast control console
The scene of the show usually has multiple separate scene program source, multiple background screen single diagram switch, so the choice of the console is very important: the first need to meet the different repertoire of the exact scene of the switch: the second all the programs are based on the timeline accurate to read-second control; the third integrated lighting is controlled according to the DMX protocol
(3) Selection of distribution cabinet
Theater stage general selection of fixed-type distribution cabinets, generally has 20KW, 40KW, 80KW, 150KW four kinds of specifications. Its multi-function card and arrester can be selected according to demand. We can generally calculate the input power of the screen according to the size of the screen body, and then select the appropriate capacity of the distribution box according to the power. Notice when choosing the Distribution box:
① the number of air head in the distribution box to meet the actual demand;
② the size of the distribution box can meet the maintenance channel size placement requirements (the larger the capacity of the distribution box, the larger the size);
③ to consider the location of the distribution box, need to consider waterproof, lightning, remote control, such as the upper and lower power.
④ to consider capacity selection, the general distribution box capacity is greater than the input power (not maximum power consumption).
Generally in a certain area, the total power consumption of more than 10KW in the case, the use of the equipment (depending on the situation).
