Thanks for the response Bruce. I’m aware of this and I know it won’t be pretty. I know that without some sort of close-mic solution as you mentioned, a very clear, present signal is not possible. I’m just looking for the best solution that doesn’t involve extra crew. As it is, they can’t hear audience questions at all. Perhaps a pair of hyper-cardioids cross-shooting the crowd kept pretty low in the mix with the presenter could at least allow a viewer to be able to make out the question? I kinda suspect that passing around a wireless mic or asking people to walk up to a “question station” mic won’t work because they are not being amplified in the room, so people will just think the mic is broken and start using it as a pointing stick. I guess one option is to actually amplify it in the room, but its such a small room, people will probably not feel that the amplification is necessary and will again not use the mic.
How about boundary mics, like they use in live theatre? or hanging mics like they do over a choir? By hanging them, we could potentially get 10-20 feet from people. Or perhaps it’s a fools errand, and it will introduce more room noise than it’s worth.
