You sound like you need to look for "mixer" circuits.

If the switch isolates the connection properly you shouldn't have a problem.

That's why you turn down, or switch off the input on the mixer That's what all the knobs DO.

Automatic levelling ??

This has turned from a simple box of switches into something quite nasty, if you want it to be automatic. You are now in the realm of AGC circuits, and mixers.

Combine them by linking + to + and - to -. Off hand, I would say that the only way that one would overpower the other would be if there was way more gain on one than the other. You could control this by adding a pot on each of the + leads before they mix.

Also, you could just go to your local pro-audio store and look at a cheap mixer. I've seen them for as low as $40.

If you give me more info about what you're trying to accomplish, I might be able to help you better. (After all... I've seen some pretty intresting things in my years as an audio production specialist.) :)
