But wait! There's MORE
If you are going to feed a camera, will that be mono or stereo? Most "pro" cameras are likely to have stereo XLR inputs(at least those at my last corporate event did). The camera also had switches to select Mic or Line input level. Since I was feeding from a console(Yamaha LS9), the Line level was selected, but as I only had a single output open on the console(and the event was mostly talking heads), I told the camera op to gran a WYE cable to feed the single line into both left and right inputs(though in post, they could have copied the audio).
Having said this, I think Darryl has given the best option
