If you are going to be interviewing people in the same room, or if you have a co-host in the same room – you HAVE to pretend your Oprah.
YOU GET A MICROPHONE – YOU GET A MICROPHONE -EVERYBODY GETS A MICROPHONE.

Don't Share Microphones
Now I know they make microphones that pick up in every angle, but you DO NOT want to do that.

I know it's more expensive, but you will LOSE your audience (or neve gain one) when your audio is bad.
Everybody gets their own microphone.
