Usage example: If you input MP3 to 1ch, smartphone sound source to 3ch, and connect headphones to outputs 2ch and 4ch. If you select input 1ch, the MP3 sound source will be played from outputs 2ch and 4ch. If you select 3ch, the sound source of your smartphone will be played from output 2ch and 4ch. In this case, the input can be switched, but the output cannot. It is also possible to use the output and input interchangeably. If you want to use it to switch outputs, connect the output to the terminal labeled IN and the input to the terminal labeled OUT. By doing so, you can channel-switch the input sound source and output only to speakers, headphones, etc. of your choice.
