14.5.2. Using the Amplifier cut off function
This connection allows broadcast from an external broadcast system to override the broadcast currently in
progress within the VM-3000 system by cutting off the VM-3000 system's built-in amplifier.
Connect the amplifier output and announcement start contact output of the external broadcast system to the
EXT. PA AMP INPUT and Emergency control input terminals of the VM amplifier, respectively.
The figure below shows an example to set this function to the Emergency control input 1.
