    Is there any possible way to have two inputs go to the same pot, and then two seperate outputs, without mixing them? or would I need to get two seperate pots to do this?

    I believe you are going to need a second potentiometer if you wish to keep the two signals seperated. You can buy what is called a ganged potentiometer if you need the two potentiometers to track one another.

    Is this the type of potentiometer that you are looking for? This is the dual or ganged pot that hgmjr mentioned.

    Hello,

    If you want the potmeters to be both on the same position, you can look for a stereo potmeter.

    Yes it is possible, in fact you could have many more than two inputs and outputs, so long as you want the same division ratio for each inputs.

    To achieve this miracle you need to feed your inputs to a multiplexer, feed the output of the multiplexer to the pot, and finally retrieve your separated outputs from a demultiplexer, fed from the pot output.

    The multiplexer may be time domain or frequency domain.
