ABSTRACT:
A signal copy device for a digital record/reproduction system includes an encoding circuit for producing a first digital encoded signal corresponding to an analog audio signal. The encoding circuit is connected to a first VTR through a switch section of a switch circuit and a first digital signal processor. A second VTR reproduces and generates a digital encoded audio signal to be copied. The switch circuit is connected to the encoding circuit and the second VTR. The switch circuit includes two switch sections which operate in cooperation with each other. When a reproduction signal is generated from the second VTR, the two switch sections are switched. The reproduction signal is supplied to the first VTR through these switch sections, thus accomplishing copying.
