PURPOSE:To avoid the trouble of the mode selection by using one switch section so as to select any of the normal mode, the voice fade mode and the multi orchestral accompaniment mode. CONSTITUTION:When moving contacts 23a, 23b are connected to normal mode position contacts 21a, 21b, a signal on inputs 1, 2 is outputted as it is to output, lines 7, 8. When the moving contacts 23a, 23b are connected to fixed position contacts 21c, 21d, a common music signal suppressing a vocal signal of a voice fader 3 is outputted to the lines 7, 8. Furthermore, when the moving contacts 23a, 23b are connected to fixed position contacts 21e, 21f, the output of the vocal signal from the input line 2 is interrupted and only the common music signal from the line 1 is outputted to the lines 7, 8. Thus, a vocal signal of a singer from a microphone amplifier 11 is added to the music signal to attain singing with the orchestral accompaniment. |
