摘要：PURPOSE:To discriminate that a voice matrix circuit is correctly operated and to attain complete check by confirming a signal sound outputted from an output terminal in respon to the changeover of a switch circuit. CONSTITUTION:Changeover switches 3, 5 are connected to the position of ON and a changeover switch 8 is connected to the position of L. When a signal tone of a frequency f2 comes from the left side channel, the operation of a voice matrix circuit 20 is implemented correctly. Then the changeover switches 3, 5 are connected to the position ON and the changeover switch 8 is connected to the position R. When a signal tone of a frequency f2 comes from the right side channel, the operation of the voice matrix circuit 20 is implemented correctly. Then the changeover switch 3 is connected to the position ON and the changeover switches 5, 8 are connected to the position OFF.
