オ音声増幅回路。 In a 2-channel stereo audio amplification circuit that outputs three types of audio signals: a monaural low-range signal in addition to middle and high-range signals for the left and right channels, two of the same characteristics are used for the left and right channels. power amplifiers, and both power amplifiers are connected to the high-frequency signal input side in their respective channels with their polarities reversed so that one becomes an inverting amplifier circuit and the other becomes a non-inverting amplifier circuit. In addition, a monaural low-frequency signal obtained by mixing the signals of both channels is equally input to both power amplifiers in the same phase, and the audio signals of the full range of the respective corresponding channels are inverted from each other from each power amplifier. 1. A stereo audio amplification circuit characterized in that the stereo audio amplification circuit is configured to output signals in phase and to output a low frequency signal from between each output of the two power amplifiers.
