Hello all,
This is my first post in this group.
I want to make an audio input switch for my stero system at home.
My sound system only has a single AUX input, although I've got a number of devices that i want selectively amplified through my sound system. I'm currently unplugging/replugging RCA wires, and i'm getting tired of it.
I was originally planning on simply buying 3 pairs of RCA connectors (input1, input2, output) and connecting them to a three-way (on-off-on) switch which could connect the output selectively to input1 or input2 depeding on its position.
But i am wondering how difficult it would be to make a small circuit capable of detecting current in both inputs and just outputting whatever input has a non-zero value, without losing any quality in the audio signal.
If both inputs have a non-zero value, it would just light up a LED to notify me that both inputs are receiving signals at the same time, and that i need to shut one of them off.
Any thoughts or links to web pages? I'm pretty new to designing my own elec circuits. I know what most electronic components do, but don't known how to select them and how to arrange them to make what i want.
thanks for your help
