急放送受信装置。In order to receive emergency warning signals and emergency information signals that are transmitted with priority over normal broadcast program signals using the same carrier wave as normal broadcasting; A detection unit that detects whether or not the emergency warning signal is included, and a first switching unit that is controlled to open and close based on the output of the detection unit, and when the detection unit detects the emergency warning signal. In a receiving device configured to supply a power supply voltage to the audio amplification unit via the first switching unit, the output voltage is controlled by an output voltage of a voltage generation unit that generates an output voltage according to a received input signal level. . An emergency broadcast receiving device comprising a second switching section that stops the operation of the detection section when the received input signal level is below a predetermined level.
