Abstract: A microphone signal is branched into a microphone sound effect generation signal path and a direct sound signal path via a microphone volume controller. The microphone signal branched to the microphone sound effect generation signal path is level-adjusted by a microphone sound effect volume controller, and then supplied to a microphone sound effect generating circuit, so that a microphone sound effect signal is generated. The microphone sound effect signal and a music signal supplied from a music signal input terminal are additively combined together by combining circuits and are output from a music signal output terminal. The microphone sound branched to the direct sound signal path is output from a microphone signal output terminal, independently of the microphone sound effect signal, improving the separation between the microphone sound signal and a microphone sound effect signal.
