How do I set up a field recorder with camera/wireless monitoring? This has to do with production sound. If you're a mixer, please help me, because I cannot wrap my head around this. I am a total newbie. 

Here's the scenario. 

Not working explicitly with this device, but since it makes for a head scratching example, take the Zaxcom Maxx (http://www.trewaudio.com/store/Zaxcom-Maxx-Mixer-Recorder.html)

This nifty little recorder has several outputs. 


1x TA5 Mono(?) tape out
1x TA5 "Aux 1/2" out, a sum of Out 1 &amp; 2
1x TA5 Stereo(?) Return
2x XLR Outputs


I am assuming from Zaxcom's manual that they are all balanced connections.

NOW. I want to send my stereo mix from the Zaxcom Maxx to a camera, which has two Mic/Line selectable XLR inputs, AND to a Comtek M-216 transmitter.

I have no idea how to do this. Obviously for camera you would use the two XLR outs with some kind of twin/braided XLR cable, right? Does that cable even exist? 

Do you use the tape out for the Comtek? TA5 to stereo mini? 

Very confused. Please help.
Easiest bet, use a distribution amplifier.  If you need the same audio to both, a DA will boost the signal so that it can actually go to both.  Not sure what the inputs on the Comtek are though, the DA will generally work best if they can both take XLR in.  Also, are you mixing in stereo?  If not, do you need two XLR to the camera?

As for the cable to the camera, you could heat shrink wrap two XLRs if you can't find a basic 2 channel XLR snake (assuming you are looking to have only one "cable" going to the camera.  Any reason not to timecode sync them and combine in post if running two cables is really a problem.
