The sound range controller automatically compensates for phase and volume components of the signal from the input matching portion according to a feedback control signal, and outputs the compensated result. The volume analyzer analyzes volumes of the signals from the sound range controller and outputs the analyzed result to the input matching portion. The feedback sound controller analyzes the range and color of the signals from the sound range controller and controls a feedback sound.
