Abstract
PURPOSE: To avoid the effect of nonlinear distortion and thus enhance the characteristics, by using the current mode for process and transmission of an internal signal.
CONSTITUTION: Each of the signals which are converted into the current signals from the voltage singals by the amplifiers 6, 10, 11, 14 and 15 is supplied to the switch means 8 and then processed in the current mode to be transmitted successively. The output of the tone control circuit 21 is supplied to the variable resistor 27 provided to the output side of the circuit 21. The resistor 27 is inserted into the input terminal of the power amplifier 28 of the next stage so as to vary the resistance value itself. Thus the gain is controlled for the amplifier 28. The current signal supplied to the amplifier 28 is converted there into the voltage signal to be delivered to the output terminal 29.
