<p>PROBLEM TO BE SOLVED: To simplify a function by means of operating a whole device in spite of a partial fault by providing a third control part and a second output part, selecting one of the first and second output parts and connecting it to an external device to be controlled. SOLUTION: The first control part 13 reads a dimming level from a first operating part 11. The second control part 14 executes two ways of operations when a storage reproducing part 12a is operated and when a setting part 12b is operated. The first output part 17 creates a prescribed output signal based on data of the dimming level which is stored in a memory 15 and on patch information stored in a memory 16 and outputs it. The third control part 19 reads the dimming level from the first operating part 11. The second output part 20 receives dimming level data of each switch 11a from the third control part 19 and outputs it by permitting the volume number of the switch 11a to correspond to its dimmer number. Then a change-over switch 18 selects one of the first and second output parts 17 and 20 and connects it to the external device to be controlled.</p> |
