PURPOSE:To provide the KARAOKE sing-along device which generates sufficient sound field effects while securing the articulation of a singing sound and easiness of singing. CONSTITUTION:The accompaniment sound from source equipment 12 and the singing sound from a microphone 14 are mixed ratio by 1st and 2nd mixing means 40 and 74 at their ratios. The mixing output of the 1st mixing means 40 is reproduced as a main signal by a main speaker 48. The mixing output of the 2nd mixing means 74 is inputted as a signal for sound field effect sound generation to a sound field effect processor 52 to generate a sound field effect sound, which is reproduced by sound field effect speakers 58 and 60. The rate of the singing sound signal in the signal for sound field effect sound generation is adjusted with a microphone variable resistor 70 and made relatively small, and the rate of the accompaniment sound signal is adjusted with a source variable resistor 72 and made relatively large to obtain sufficient sound field effects while securing the articulation of the singing sound and the easiness of singing. |
