Hi Folks, Unlike desktop sound cards, which usually have a "Line In" socket for headphone/speaker output (aka "Line Out") from audio devices, most laptops seem to have only microphone input (though they do have "Line Out").
So it would be nice to have a means of putting a cable between the "Line Out" and the mike input on the laptop, but I've not managed to work out a way of doing this!
Does anyone have a good solution?
So assuming that you want to connect a line-out on one machine (probably not a computer) to the mic-in on the laptop all you need is a simple attenuator.
IIRC, the line out gives 1 volt pp and expects a 100Ω load and the mic in expects 100 mvolt pp from a 10KΩ source.
So a few resistors from the junk box[1] should do the trick.
Well it did for me.
Of course it gets a bit more complex if you're going from a stereo line-out to a mono mic-in. IME most mic-in are mono.
[1] do people still have junk boxes these days?
