A stereo audio detection circuit that detects an audio signal and outputs it as a left channel signal and a right channel signal, and inputs the audio signal of this stereo audio detection circuit and determines whether this signal is a stereo signal or a monophonic signal. and is connected between a discrimination circuit that outputs a discrimination signal, and a stereo audio output circuit that inputs, amplifies and outputs the left and right channel signals outputted from the stereo audio detection circuit and the stereo audio detection circuit, respectively. If the discrimination signal indicates a stereo mode, the left and right channel signals are guided to the stereo audio output circuit, and if the discrimination signal indicates a monophonic signal, the left and right channel signals are converted into pseudo-stereo signals. 1. An audio output circuit comprising switching means for guiding the audio signal to the stereo audio output circuit after passing through a space wide circuit for the purpose of the audio output circuit.
