Public broadcast PA system 100V output power amplifier drives parallel loudspeaker. Built-in front amplifier and player

 Broadcast system power amplifier product functions:
1: the power amplifier design of public broadcasting system includes indoor and outdoor areas.

2: Public Broadcasting System is partitioned according to outdoor buildings. Such as shopping malls, hotels, scenic parks and schools.

3: the power amplifier of the public broadcasting system regularly plays background music in each area, and each public area can play different background music at the same time, and can also play the same background music.

4: The broadcasting room can broadcast speech and broadcast notification to any one partition power amplifier through paging microphone.

5: the power amplifier of the broadcasting system can be linked with the fire protection system (switching value signal needs to be input externally, and XBPA-5600 fire protection broadcasting host is selected). In case of emergency, the broadcasting system can play fire emergency signals to remind the building staff to evacuate in time and ensure the personal and property safety of the army staff and patients.
