In doing some research for a mic splitter I'm building it became obvious that I should have one isolated out and one pass through instead of just building essentially 16 y-cables in a box. There are a number of reasons and what I want to know is if there is a way to do it without buying 16 trannies. Transformers are the right way to go but the Jensens are cost prohibitive and so are Lundahl. I couldn't find a price on Cinemag but my guess is that they are too. Resistors are much cheaper and in my mind could provide a mic with the amount of resistance it wants to see. Is this true? So here are my questions: If I want to use resistors should I put a resistor each across the hot and neutral legs of the output? What Ohm rating should the resistors have? Also is there a way to isolate one split from phantom power? what if I were to permanently lift the ground, that would certainly not pass phantom but what are the reasons this should not be done? Any other input on the subject is welcome.
