In the generic cabling system, the broadcast system software has been ignored by many people. Today, we will introduce three common public address system software in detail, and teach you to use it properly according to the details. At the end of the article, we will continue to explain in particular how to choose the best broadcast cable:
The public address system software is mainly divided into business broadcast, service broadcast and safety accident broadcast.
Business broadcasting is mainly set up in some large and medium-sized public places, such as commercial office buildings, colleges, processing plants, shopping malls, office buildings, large and medium-sized apartment buildings, in order to take into account the broadcasting announcements, remote control communication systems, administrative management and other work of some ordinary business processes. The broadcast target is all the members in the relevant broadcast area, so the output power and noise coefficient of the speakers used are relatively large. In the exhibition hall with a ceiling less than 3 meters high, the ceiling speakers can generally be arranged symmetrically at a distance of 5 to 8 meters.
Service-based broadcasting is the familiar music background broadcasting and the variety show broadcasting in some hotel rooms. Its purpose is to show you a relaxed music background and create a relaxed, warm and happy working and living environment. Therefore, the speaker used in the public broadcasting system software with music background is generally low in output power and noise coefficient, In addition, the spacing of speaker layout is also larger than that of business broadcast, which can generally achieve a symmetrical layout of 8 to 12 meters.
Fire safety broadcasting is mainly to better early warning information in case of fire in the building and facilitate the fire rescue staff to correctly guide the group to evacuate quickly from the dangerous area according to the broadcasting microphone in the main control room. Its necessity can be ranked first. Therefore, its site setting standard is also very strict. The distance from the relevant broadcast design standard requirements: "The total number of PA loudspeaker in the walkway, service hall, restaurant light and mass area should ensure that the walking distance from all positions on a certain floor to the nearest speaker is not more than 15m. Horn Speakers should be set at the junction of the walkway and at the corner. The last speaker horn at the end of the walkway should not be more than 8m away from the wall".
For public broadcasting, most people focus on whether the supporting facilities among the machinery and equipment and whether the quality of the commonly used machinery and equipment is excellent. In fact, the selection of broadcast cables is also a key factor that endangers the actual effect of the final broadcast. No matter how good the machinery and equipment are applied immediately, the actual effect of broadcasting can not be satisfied if the cables are not properly selected.
