As a small user-group we regularly organize mini conference with a few talks and 60-140 attendees.
We have a nice portable setup for recording the talks (Camera->HDMI->MacBook->Wirecast). The presenter sounds great thanks to the RodeLink FilmMaker.
The next challenge is to find how to record the questions from the attendees. (small team, pretty relaxed atmosphere: we don't want to bring a mic to the person)
Here are the combinations I gathered:
condenser / cardiod, placed 1 m in front of the presenter, pointing to the crowd
condenser / cardiod, placed on each front side of the crowd, 2m high?(basically above the crowd)
XY (because we have a Zoom H4) in front of the room.
boundary mic? Not sure how to place it.
It seems to be an interesting challenge because we organize those events in different places with very different acoustics (company lounges, one with very high ceiling...)
What do you think would work reasonably well, but also as light as possible?
Additional requirement: we are live-mixing/recording, so the sound must be fed to MacBook, not just recorded.
Note: I know there is no magical solution, I'm only trying to find a simple way to make the questions intelligible.
