Abstract

PURPOSE:To perform reproduction by performing the mixing of a play signal and a mike signal by prohibiting the reproducing output of a singing signal recorded on another channel of a sound multiplex recording medium corresponding to the presence/absence of the mike signal. CONSTITUTION:When singing is performed by connecting a microphone to a microphone input terminal 3, the mike signal is inputted to a rectifier smoothing circuit 13 via a mike amplifier 6 and a buffer amplifier 12. A control signal generated from the circuit 13 is inputted to the base of a muting transistor (TR) 14, then, the TR 14 is turned ON, therefore, the reproducing output of the singing signal of a singer that is a model obtained at the output terminal of a second pre-amplifier 5 is grounded via the TR 14, and transmission to a succeeding stage is prohibited. Meanwhile, the mike signal from the mike amplifier 6 is impressed on a point B via a volume 17, and is mixed with the playing signal, and is outputted from an output terminal 20 via a main volume 18 and a main amplifier 19.

A normal karaoke device is equipped with an audio multiplexing volume for relatively changing the playback output of one channel and the other channel, and when using the audio multiplex recording tape as a performance tape, the The above-mentioned drawbacks are improved by manually operating the audio multiplex volume to attenuate the singing signal obtained from the audio multiplex recording tape to obtain a playback output of only the performance signal of one channel. However, when using the audio multiplex recording tape for singing practice and comparing the singing of a model singer with one's own singing, manual operation of the audio multiplex volume is extremely troublesome and operationally difficult. It's very inconvenient.

For example, with a magnetic tape in which audio is multiplex recorded in this way, a male user inputs his own singing voice into a microphone and sings with the male singer where the male singer's voice is being played, and sings with the male singer when the male singer's voice is being played. It is possible to enjoy a duet in a way that allows you to listen to the female singer's playback sound without having to listen to the female singer's playback sound.

However, in conventional microphone mixing circuits, the male singer's singing signal and the microphone signal from your own microphone are mixed together and played back, so you can take the place of the male singer and alternately listen to the female singer being recorded. I can't enjoy singing signals and duets.
