| Zusammenfassung: | PURPOSE:To eliminate the need of executing a processing of jumper wiring, etc., at the time of changing a transmission system, by switching an unbalanced transmission/balanced transmission system by an unbalanced transmission/ balanced transmission designating relay switch. CONSTITUTION:Switching of an unbalanced transmission/balanced transmission system is executed by an unbalanced transmission/balanced transmission designating relay switch 4, and use/unuse of a terminator 3 is executed by a terminator use/unuse designating relay switch 5. That is, the terminator use/unuse designating relay switch 5 connects/disconnects a terminator for an unbalanced transmission, and a terminator for balanced transmission between a power source and a ground. In such a way, the transmission system can be switched easily, and it becomes unnecessary to insert and remove a module resistance being the terminator. |
