(54)	On-Vehicle Receiver

(57) An on-vehicle radio receiver comprises a tuning circuit (2,3) for receiving a radio broadcast wave in which a data signal is multiplexed with a main signal including traffic information. The data signal indicates that the traffic information is on the air. A demodulating circuit (4) demodulates the radio broadcast wave to extract the main signal from the radio broadcast wave received through the tuning means. A decoding circuit (10) decodes the radio broadcast wave, received through said tuning means, to extract the data signal. A controlling circuit (11) for outputting a control signal on the basis of the data signal. An audio signal processing circuit causes the output level and the frequency response of the main signal including the traffic information in response to the control signal.
