The level control part generates first, second, and third control signals(A,B,C) in response to the level selection signal. The accompaniment equalizer control part controls the equalizer of an accompaniment in response to the first control signal generated from the level control part. The accompaniment volume control part controls the volume of the accompaniment in response to the second control signal generated from the level control part. The microphone volume control part controls the volume of a microphone in response to the third control signal generated from the level control part.
