Are you really really sure there are no transformers in the path or some other circuitry? You mentioned something about these cables being built into the stage, so how do you know they are really just cables? All in all this sounds like a bad idea. Even if you do just have cables with no electronics, you still end up with two separate signals squished next to each other in a common run. I expect you would get some crosstalk. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
