Control circuits for the cut-off and drive control of video equipment. A first control device includes a cut-off control circuit and drive control circuit for use in conventional modes. A second control device includes a cut-off control circuit for mode switching and a drive control circuit for mode switching, independent of the first control device. The cut-off and drive adjustments made for every mode switching operation are unnecessary, and the mode switching based on off set data is possible.
