PURPOSE:To provide constitution, simplified as much as possible, with many functions by arranging a change-over switch and adder in front of a PCM recording system. CONSTITUTION:When change-over switch S1 is set to contact A, VTR16 for PCM is placed in normal PCM recording mode. With S1 set to contact B next, the output of VTR16' is supplied to VTR16 for digital dubbing. Further, when an analog signal is applied to terminal IN with S1 set to contact C, digital addition 22 to the output of PCM reproducing system 19 comes into effect and digital mixing is carried out through PCM recording system 15. |
