PURPOSE:To constitute a home bar system with each one of transmitter and receiver irrespectively of the number of information transmitting media, by connecting plural information transmitting media with the plural secondary windings of a pulse transformer having plural secondary windings and each one of transmitters and receivers with the primary winding of the transformer. CONSTITUTION:A pulse transformer 21 is equipped with plural secondary windings and each one of transmitter 19 and receiver 20. Information transmitted from communication equipments 8 and 9 is transmitted through information transmitting media 16 connected with the communication equipments 8 and 9. The information is also simultaneously transmitted to other information transmitting media by means of the pulse transformer 21 having plural secondary windings. At the same time, the information is also transmitted to a control device 1 through the receiver 20 connected with the primary winding of the pulse transformer 21. Moreover, information transmitted from the control device 1 is amplified by means of the transmitter 19 connected with the control device 1 and can be transmitted to all information transmitting media by means of the pulse transformer 21. Therefore, necessity of the transmitters and receivers by the number of the information transmitting media is eliminated as compared with conventional ones and each one of transmitters and receivers can constitute one system.
