PROBLEM TO BE SOLVED: To obtained a karaoke device capable of satisfying both of the condition easy to listen for audience and the condition easy to sing for singer by dividing the microphone input signal into two systems, and separately controlling the sound tone for each system, and providing the sound from the two systems together to the singer. SOLUTION: A second pre-amplifier 11, a second power amplifier 12 and a second stage speaker 13 are added to the conventional constitution, and a microphone signal is divided into two systems for control. The second pre-amplifier 11 appropriately processes the sound signal from a microphone 1 for outputting. The second power amplifier 12 appropriately amplifies the sound signal, and regenerates the sound through the second stage speaker 13. The second stage speaker 13 is located near a singer while being directed toward the singer so that the singer can listen to both the sound from the two systems at the same time. With this structure, the singer can sing a song in the condition easy to sing. |
