Abstract

PURPOSE:To secure the fixed holding for the aural output sent from the speaker regardless of the absence or presence of the additional signal be switching the amplification factors of the compound output signals in coupling to the switching action whether or not the additional signal is delivered from the output of the multiple demodulation circuit. CONSTITUTION:The right and left aural signals of the stereo signals are delivered to output terminals 7 and 8 of multiple demodulation circuit 2, and at the same time the main or secondary aural signal of the hetero-broadcast is delivered. The output signal of circuit 2 is applied to additional sound switch circuit 16 via amplification switch circuits 14 and 15; the output of cirucit 16 is applied to compound circuits 20 and 21 via delay circuit 17 and defeat circuit 18; and the output of circuit 18 is compounded to the output of circuits 14 and 15 in the opposite polarity. And the output of circuits 16, 17 and 18 are switched by the output of broadcast mode detection circuit 3, and then the additional signal is added to deliver the aural signals suited to each broadcast mode. Coupling to this action and with the output of additional switch circuit 22, circuits 14, 15 and 18 are switched to switch the amplification factors of the compound signals. Thus the level of the aural output can be held constant.
