发明名称 OSCILLATOR, ACOUSTIC EQUIPMENT AND SOUND ADJUSTMENT METHOD
摘要 PROBLEM TO BE SOLVED: To provide the an oscillator of frequency independent variable type in which when output signals of the same frequency are sent to plural output lines, phases of the signals of the lines are in matching with each other. SOLUTION: A switching circuit 23 is inserted between two oscillators 21, 22 and an L side output terminal ϕL and an R side output terminal ϕR. As shown in states (1) to (5) of the figures, a system controller 18 gives coefficient data to the 2nd oscillator 22 to change the oscillating frequency of the 2nd oscillator 22 into 400Hz. Then a moving contact 23Lc of the L side switching circuit 23L is thrown to the position of an L side fixed contact 23Lb, as shown in the state (2). In this state, a continuity check with an output device is conduced. Then as shown in the state (1), the moving contact 23Lc of the L side switching circuit 23L is thrown to the position of an L side fixed contact 23La. At this stage, an interface of balance transmission is checked.
