ト回路。 In a karaoke circuit that includes a microphone, microphone amplifier, preamplifier, mixer, power amplifier, and speaker, a key controller is connected in parallel between the microphone amplifier output side and the mixer, and the key controller performs frequency conversion to change the key. The audio signal from the microphone is frequency-converted by the key controller according to the operation signal of the key pitch switch connected to the key controller, and the converted frequency signal and the unconverted audio signal are synthesized by the mixer. ,2
A duet circuit for karaoke, characterized in that synthesized voices of different types or more are reproduced from a speaker.
