    Hi, I need to know how to convert stereo into two channel mono for a toolbox, so I don't have to do it in a phone every time.

    Take two resistors R1 and R2 of equal value. One end of R1 is connected to Left Channel stereo source. One end of R2 is connected to Right Channel stereo source. Join the other ends of R1 and R2 and connect to both mono channels.

    What is the source of the stereo signal?
    The value of the resistors R1 and R2 will depend on the stereo source.

    For LINE OUPUT, use 470-1000Ω resistors.

    For PHONE OUTPUT, use 33-100Ω resistors
