PURPOSE:To allow free selection according to the choice of the user by enabling the voice and image to be reproduced simultaneously even when the voice and image are not paired in a source. CONSTITUTION:When an operating switch 232A is pushed on, H outputs are transmitted from flip-flops 17A, 18A to analog switches 13A and 14A to turn them on. Therefore, music signals connected to terminals 11A and 12A and video signals paired thereto are outputted at first and second outputs 15 and 16. When an operating switch 23D is pushed on, only the output of the inverter 21D of the inverters 21A to 21F goes to H hence, only 13D of analog switched 13A to 13F are turned on while AND type circuits 20A to 20C and inverters 22A to 22C remain unaffected.
