在搞好安全播出,实现广播自动化的过程中,我们试验成功一种扩音机自动倒换电路,这种电路的作用是:如主机出现故障能马上切断主机电源,并能自动接通备机电源,从而避免广播中断。
In the process of doing a good job of broadcasting safety and broadcasting automation, we successfully tested a type of automatic amplifier amplifier switching circuit. The function of this circuit is that if the host fails, it can immediately cut off the power of the host and automatically turn on the standby power, Thus avoiding broadcast interruptions.
