力切換回路。 Equipped with multiple sets of input terminals that pair the audio signal inputs of the right and left channels, and an input switch that simultaneously selects one of the same inputs for each left and right channel.The output signal of the input switch is amplified and output. In the input switching circuit of a stereo device, a second input switch simultaneously selects one of the branched inputs for each left and right channel, and a second input switch that mixes the left and right channel signals output from the second input switch. and a first mixer that mixes the left and right channel signals output from the first input switch, and the output of the first mixer is connected to the left channel, and the output of the second mixer is connected to the left channel. a signal with the right channel as
A third input switch selects either of the left and right channel signals output from the first input switch, and the left and right channel signals output from the third input switch are connected to the amplifiers of the respective channels. An input switching circuit for a stereo device, characterized in that the input switching circuit supplies a signal to a supply device.
