Abstract

PURPOSE: To prevent the occurrence of the harmful distortion sound when the velocity of the tape is switched, by generating the muting signal through the control given to the switching transistor via the timing switch which interlocks the tape velocity switch.
CONSTITUTION: A temporary short circuit is given between the terminals (a) and (b) of the timing switch 21 interlocking the tape velocity switch and simultaneously with the switching of the tape velocity. And thus a conduction is secured to the switching transistor 8 the malfunction of which is prevented by the parallel resistance 18 and the diode 19 pulse via the DC power source 6. And this conduction of the transistor 8 is continued for a fixed time by the multiplex voltage of the capacitors 13 and 16 in the serial circuits 12 and 15. As a result, the muting signal is generated from the collector of the cntrol transistor 7, and thus the harmful distortion sound produced at the switcing of the tape velocity is never applied to the main amplifier. Thus the occurrence of the harmful distortion sound can be prevented until the velocity of the tape becomes steady.
