Still an issue trying to do a matrix recording when you then have two unsynced sources. I am trying to avoid having to match them up in post when they won't be locked together and one or the other sources may drift. I was hoping there was a reasonably affordable wireless technology fix available, but perhaps not.
If you don't want to deal with the delay thing or syncing up 2 sources. I don't. The answer is simple. Run mics on stage and run the cords to where the board is. That sort of thing has always worked out good for me. I like having the sound guy send me a feed from the snake to the stage and record from there. That usually requires a pair of female to female barrel XLR's @ the board and a pair of male to male XLR's to get from the stage snake to my deck. Don't forget about asking if there are 2 spare channels in the snake for you to use. It can make the impossible possible. You guys know all this though!!!
