PURPOSE:To easily check an editing machine by providing the editing machine with the control signal processing system of two channels to form a confirm signal by using the control signal processing system of another channel at judging whether or not the control signal processing system of one channel is sound. CONSTITUTION:An editing machine 2 contains many control signal processing circuit sections in accompanying with the mode command signal of an operation switch 13 disposing a control signal processing circuit 10 in an operation panel in response to many operation modes. A ''player reproduction'' mode signal processing circuit 21 has A-channel and B-channel signal processing systems 21A and 21B and sends a reproduction mode command signal S1 generated at a ''player reproduction'' operation switch 22 installed to the panel of the editing machine 2 to a reproduction mode signal formation section 23. The processing circuit 21 also gives a ''player reproduction'' mode signal S2 produced at the section 23 to an A-channel input-output circuit section 5A of an input-output circuit 5 as time serial data. |
