I want to be able to switch between my MD2 mic which needs DC applied to the AF line and my Heil Proset Plus headset which doesn't.
I'm not sure I could fit the resistor that comes with the MD2 inside the female connector at the mic side so I'm looking into connecting pins 6 and 1 together in the female mic connector and putting the resistor in SERIES with the 5 VDC line going to pin 6 at the male end of the jack. When the MD2 is plugged in the AF line would get DC applied through the dropping resistor in the 5 volt line. When I plug in the Proset Plus pin 1 is just audio and no DC applied. Does anyone see a problem with doing it this way? I know you won't be able to pull a lot from the 5 volt line after this mod but I don't plan on powering anything else off of the mic connector. Also...I would not be able to plug my mic into someone else's K2 as it would put the unlimited 5VDC line directly to my mic element. I practice safe microphoning and never insert my mic into any other K2 except my own so I'm not concerned in either case. Comments? Suggestions?
