<p>PURPOSE:To eliminate the need of a dedicated switch, etc., and to improve the operability by operating simultaneously two switches having functions which are different from a fader start function, operating a changeover means with a deciding means and making a changeover of the fader start function accordingly. CONSTITUTION:The fader start function 7 for starting a reproducing operation by operating a reproducing level adjusting means for adjusting a reproducing level is decided as to whether its function is effective or ineffective by the deciding means 6. The 1st and 2nd switches 1 and 2 are for operating their respective functions which are different from the fader start function 7, and when the 1st switch 1 is singly operated, the 1st function 3 is operated, and when the 2nd switch 2 is singly operated, the 2nd function 4 is operated. When the 1st and 2nd switches 1 and 2 are simultaneously operated, the changeover means 5 is operated to make a changeover to the state opposite to a decided result of the deciding means 6, and the effectiveness/ineffectiveness of the fader start function are switched.</p> |
