の信号切換回路。[Claims for Utility Model Registration] Output mode setting means for outputting a control signal for selectively outputting a two-channel audio signal of stereo, monaural, or dual audio from an audio multiplex decoder; and the audio multiplex decoder. A first input switching circuit selectively outputs two channels of audio signals from the line input terminal and two channels of audio signals from the line input terminal; A second input switching circuit that outputs an audio signal, a recording and reproducing circuit that records and reproduces two channels of audio signals from this second input switching circuit, and selects each of the two channels of audio signals output from this recording and reproducing circuit. and an output switching circuit for outputting a two-channel audio signal, wherein the output mode setting means outputs the control signal for dual and the first input switching circuit outputs the dual-channel audio signal. The video apparatus is characterized in that it comprises switching setting means for controlling the second input switching circuit and the output switching circuit in conjunction with each other when the audio signal of two channels from the audio multiplex decoder is selectively output. Tape recorder signal switching circuit.
