PROBLEM TO BE SOLVED: To obtain a demodulator whose sound adjustment operation is easily conducted. SOLUTION: The demodulator 1 is provided with a decoder 4 that is configured to be connectable to a receiver 21 varying a level of a received output signal SB and converts the received output signal SB into an analog signal SAF, and also provided with a level detection circuit 8 that detects a level of the received output signal SB and with a 1st level setting circuit 5 that sets a level of the analog signal SAF converted by the decoder 4 to a level in response to a detection signal SDC of the level detection circuit 8. |
