What are Lavalier Microphones?

"Alright, so now I'm going to talk about my favorite microphone, the Lavalier. Basically, it's the way I shoot, I'm typically shooting one person talking, almost interview style, but not always, and the Lavalier microphone is perfect for that. Wireless, I don't have to worry about any cables dragging from the person to my microphone, and it picks up fantastic sound just in the general area around that person, which is them talking, obviously. Here's my wireless Lav. set down here. It's a really great set, I really like it. It's very small and, basically, it's working on radio frequencies to connect wirelessly. Then you have this little tiny microphone that connects to our receiver right here, excuse me, our transmitter. This will attach to somebody's belt and then they'll run the microphone up their shirt. Actually the video you?re watching right now, we're recording with a wireless Lavalier because it's the best option for this video where I'm just talking. See, it's up here on my shirt. So, when you're thinking about external microphones you have to think about what mic fits the situation. The Lavalier microphone will definitely fit in interview situation and is a real easy mic to set-up for that kind of shot where it's just one person talking. Now, if you've got a whole big group of people and you want to be hearing everything, Lavalier is probably not going to be good, because the person over here is not going to nearly as loud as I am with the microphone turned on. In that case, you'd probably go to something else. But, fantastic microphone for an interview situation or when you just want to hear one person talking. We'll go ahead and get this microphone set up next."
