<P>PROBLEM TO BE SOLVED: To more properly make adjustments concerned with a microphone of a karaoke machine for inputting a singing voice. <P>SOLUTION: An adjusting operator voices "Testing a microphone now." in front of the microphone 33 and then the input voice is converted into a digital voice signal, which is temporarily stored on a HDD 13. Then the stored voice signal is outputted as an audible sound from a speaker 32 and then the adjusting operator is able to objectively hear his or her voice. The adjusting operator who wants to vary the extent of sound effect to be imparted only makes an adjustment indication through a console panel 10. In response to the adjustment indication, a CPU 14 controls a microphone input level volume circuit 21, a microphone volume circuit 26, and a digital effect circuit 20, so the adjusting operator is able to confirm the state after the adjustment with the audible sound generated by the speaker 32 and further make adjustments. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
