you don’t actually need to connect them both to your camera. all you need to do is have a clapperboard, which you clap in front of the camera. you then line up the spike of the audio, with the spike of the audio that is from the camera microphone, and the video of the clapperboard clapping. that way you can have microphones that are just connected a standalone recorder and have as many microphones as you want, and it only limits you to post production editing (not by the fact that you are using a single audio jack).
