Is there a way to simplify this setup? I'm trying to record multiple lav mics on one camcorder.

a. 4 lav receivers plugged into a mixer
b. 1 transmitter on the mixer sending all the audio to another receiver on the camcorder

Assuming you have to stick with all wireless thats probably as basic as it'll get.

If you can try and hard wire as many of the mics as possible. It will lower the risk while recording.

Personally, I wouldn't go that "simple" (unless it truly doesn't matter)
as any of those 4 mics has drops or
has other problems, it will spoil ALL the audio.
