Summary:In a circuit including a voice decoder unit(4); a pilot signal detector(5) for detecting a pilot signal from the voice decoder unit; a voice matrix circuit(6) for stereo/mono processing depending on the control signal, An IF circuit generates an AGC voltage depending on the level of the selected broadcasting signal and an AGC voltage detector produces a forced mono signal, then the pilot signal detector set the voice matrix circuit to a mono mode if the forced mono signal from the AGC voltage detector is received.
