Factories set background music system broadcasting equipment SXOPA Cheung gull brand. According to Xiang gull factory planning and design of specific circumstances, we have designed a set of centralized control transmission of audio signals from a reliable and practical background music, public (emergency) broadcast systems. That design background music and fire emergency radio broadcast compatible. All the background music speaker in a fire could cut to the fire emergency broadcast strong state. When the normal background music broadcasting, once the fire alarm, the automatic trigger voice systems, emergency radio broadcast cut to a strong state to achieve the highest priority to the district partition emergency broadcast, and can be broadcast to deal with accidents artificial avoided The possibility of misuse caused hurriedly. Factories set background music system broadcasting equipment SXOPA Cheung gull brand. As the factory covers an area of ??large, plant more. To facilitate the broadcast, the broadcasting system should be divided into several zones, so that in different situations can be partitioned broadcast or partition paging. Depending on the plant's requirements for public broadcasting, public broadcasting is divided into a total of eight regions (specific configuration table). 1.1 Speaker aspect: In consideration of the environmental factors, so the use of suspended ceiling speakers (3W / 6W) within A) office building. B) the use of the plant each plant fret speaker (40W) C) canteen on the first floor, second floor, using two frets D) were set 36 outdoor grass lawn speaker (30W, 40W) E) Dormitory wall speaker installation (6W / 10W). Factories set background music system broadcasting equipment SXOPA Cheung gull brand. In simple principle, we use the control panel to the central master control system equipment, all programming operations focus on the completion, no need for a DCI broadcasting equipment operated individually, just in the center of the control panel where control various public broadcasting equipment will be able to by the central control console can be timed to open source to automatically select the program source, automatic control program source play a track, the track program source regularly sent to the appropriate partition, working status of the remote device can be displayed on the control host, in Host control various operating modes can be set according to customer requirements, convenient and simple to operate.
