五插入连接法的应急使用(设定延时时间为30秒)插入连接法中的应急开关对于防范不当信号一般调整为视音频同质同切(所谓同质指视音频为相同信号源)。但对技术性故障的防范又最好是异质同切(所谓异质指视音频为不同信号源)。原因是插入连接法延时器的输出只是应急开关的一个输入点,除非立刻使用延时器的傍路开关(BYPASS),
Emergency use of the five plug-in connection method (set the delay time of 30 seconds) into the connection method of the emergency switch for the prevention of inappropriate signals are generally adjusted to video and audio homogeneous cut (so-called homogenous refers to audio and video as the same source). However, the prevention of technical failures and the best is heterogeneous with the same (the so-called heterogeneous refers to different sources of audio and video). The reason for this is that the output of the delay timer is simply an input to the emergency switch unless the delay’s bypass switch (BYPASS) is used,
