Abstract
In a karaoke vocal adaptor 100, voice signals to which a harmony effect is imparted by the harmony effect imparting circuit, and voice signals to which the harmony effect is not imparted are output from wet voice output terminals 121 and 122, and dry voice output terminals 111 and 112, respectively. In a karaoke amplifier 200, an echo is imparted only to voice signals input through dry voice input terminals 221 and 222, by an echo imparting unit 233, the voice signals are then mixed with voice signals input through wet voice input terminals 241 and 242, and musical signals input through music input terminals 251 and 252, and the mixed signals are output.
