I had the chance to test out the Rode SC6 mic adapter a couple weeks ago during a Facebook Live broadcast. I plugged in two Rode smartLav mics for the two on-camera hosts. The adapter itself was plugged into an iPad Mini 4.
I have to say the sound quality was crisp and the setup was easy. I was using the Switcher Studio app for broadcasting, and the audio was recognized right away without adjusting any sort of settings.
The only minor drawback here is that with a device like this there’s no way to adjust individual mic levels when you have two lavs plugged in, other than changing the position of the mic on the subjects.
This broadcast was done in a quiet room, and the overall production was incredibly simple, so that really wasn’t an issue. For $19.95, it’s absolutely worth it for small projects.
