。[Claims for Utility Model Registration] Amplifier circuits are provided in each of the left and right audio signal paths, a main speaker is connected to each output of these amplifier circuits, and a connection between the outputs of both amplifier circuits is ON/OFF. In a surround circuit having a structure in which surround speakers are connected via a surround changeover switch that switches OFF, a signal limiting circuit that limits the level of an audio input signal is provided in each of the left and right audio signal paths, and the surround changeover switch The surround circuit is characterized in that an interlocking changeover switch is provided that connects the signal limiting circuit to the input side of the amplifier circuit when the surround speaker is connected between the outputs of the amplifier circuit with the surround speaker turned on.
