音声出力回路。[Claims for Utility Model Registration] (1) External input means into which an audio signal is input, an audio circuit that amplifies the audio signal from this external input means, and an external output that outputs the amplified audio signal to the outside. In the audio/video equipment, the audio signal input to the external input means is input to the audio circuit when the audio circuit is powered on, and when the audio circuit is powered on, the audio signal input to the external input means is inputted to the audio circuit. 1. An audio output circuit for audio/video equipment, characterized in that an audio output circuit for audio/video equipment is provided with a changeover switch means for allowing the input to pass through to the external output means without inputting to the audio circuit when the audio is not in use. (2) A claim characterized in that it has an audio recording function and a timer, and includes a changeover switch means for passing an audio signal input to the external input means to the external output means when the timer recording is in a standby state. 1. The audio output circuit of the audio/video device according to 1.
