Abstract: PURPOSE:To freely set the output impedance of a power amplifier in each frequency band by providing a voltage feedback means and a current feedback means and feeding back voltage divided by each speaker and each detected current of speakers to the input side of the power amplifier. CONSTITUTION:A voltage proportional to the terminal voltage of a tweeter 13 is taken out at a voltage dividing point A of a voltage divider 32, and a voltage proportional to the applied current is taken out in a resistor 33 to detect the applied current.
