Abstract

PURPOSE:To constitute a device so that a transient waveform is not generated by sound control voltage, and a sound output signal gives no sense of incongruity to a listener, by comparing plural output voltages by a comparing and switching circuit, and outputting the higher sound control voltage. CONSTITUTION:Sound control voltages A, D from sound control voltage generating circuits 15a, 15b are applied to a comparing and switching circuit 18. The comparing and switching circuit 18 compares the sound control voltages A, D, irrespective of the diversity switching operation by diversity switching voltage E, its higher sound control voltage is outputted as high sound control voltage F, is applied to a high quality adjusting circuit 9 and is operated, by which a high quality characteristic is controlled. In this regard, (a), (b), 2a and 2b, 3a and 3b, 4, 5a and 5b, 6a and 6b, 7, and 8 denote a receiving circuit system (a), a receiving circuit system (b), high frequency amplifying stages, mixing stages, a common local oscillating stage, intermediate frequency amplifying stages, detecting stages, a sound signal switching circuit, and a multiplex demodulating circuit, respectively.
