キシング回路。[Claims for Utility Model Registration] A monaural audio signal source that outputs a monaural audio signal, and a first output signal line and a second output signal line branched in parallel from a single audio output signal line from the monaural audio signal source. an output signal line; first and second switching elements provided on each of the first and second output signal lines; and the first and second outputs at a stage subsequent to the first and second switching elements. R on each signal line
a stereo audio signal source that outputs a channel audio signal and an L channel audio signal, and when there is no monaural audio signal output from the monaural signal source, the first and second switching elements are rendered inactive, and the stereo An R channel audio signal and an L channel audio signal are output from the audio signal source to the first and second output signal lines, respectively, and when there is a monaural audio signal output from the monaural signal source, the first and second output signal lines are output from the audio signal source. What is claimed is: 1. A mixing circuit comprising: activating a switching element and mixing the monaural audio signal output with each channel signal output from the stereo audio signal source.
