<p>PROBLEM TO BE SOLVED: To provide an automatic monitor that can identify whether a fault has taken place in a receiver or in a simultaneous amplifier section for supervision, when the output of a multi-channel simultaneous amplification relay broadcast device has decreased. SOLUTION: The automatic supervisory monitor 10 detects the output signals of each receiver and compares them to detect a fault of a receiver, detects the output signal from the simultaneous amplifier section, and compares the output signal with a reference signal to detect output decrease, applies comparison and processing to the decreased output and the fault in the receiver, to detect the fault of the receiver and the fault in the simultaneous amplifier section and provides an alarm output externally for display, when each has caused a fault. Accordingly, distributor is dispensed with.</p> |
