Abstract

PURPOSE:To achieve rapid switching control by permitting part of a control voltage to rise and fall suddenly, by adding a voltage dividing circuit to an integral network which generates a control voltage. CONSTITUTION:A control voltage generating circuit 60 is constituted by adding a voltage dividing circuit 94 composed of resistances 90 and 92, dividing and extracting the applied voltage of a resistance 82, to an integral network 88 composed of the resistance 82 and a capacitor 84. A control voltage extracted at a connection point between the resistances 90 and 92 is applied to the input terminal 58A of a recording, reproducing and muting control circuit 56. Consequently, when a changeover switch 86 is switched, part of the control signal is controlled to rise and fall suddenly. Therefore,switching control over respective modes is exercised rapidly through the switching operation of the changeover switch 86. This method is applicable to various control circuits which employ a voltage setting method.
