Abstract

PURPOSE: To obtain the desired sound recording and reproducing characteristics, by providing the active switching element in order to secure the perfect separation between the sound recording action and the reproducing action.
CONSTITUTION: Active switching element 13 which operates on the control signal is connected between record amplifier gain control circuit 8 and record amplifier 4. In the case of the recording action, the control signal supplied is then supplied to both electronic change-over switch 11 and active switching element 13. Thus element 13 is turned on, and then the recording is carried out with the desired recording characteristics and via circuit 8. In the case of the reproduction, no control signal is supplied and the earth level is supplied to both electronic change-over switch 11 and active switching element 13. As a result, control terminal 13a of element 13 is turned off with the recording circuit cut off. Accordingly, the desired reproduction characteristics can be obtained in the same way as the recording characteristics.
