Hi Collin:
Your wedding is probably over by now but I’ll throw in my two cents. I am also a wedding videographer and I use a Zoom h1, which I love. Unless I misunderstood, I believe you said you have two transmitters and two receivers, no? You just wanted to use only one receiver since you only have one zoom recorder…. correct? If so then use both receivers and split the audio coming into the zoom, which has a stereo input. You would just need a stereo 1/8th inch to two mono 1/8th inch cable to accomplish that.
Question for you… I am thinking of purchasing a used set of EW 100’s. Do you know if the receiver has a thread on the back to attach a hot shoe mount?
All the best.
