Reply #3: Sorry, but there isn't such a microphone in the entire world!

They would have to use a compressor along with a noise gate - which is used in all broadcasting. And they will use unidirectional microphones that amplify the directional signal and suppress somehow the surround noises in all broadcasting, when there's a single speaker. The effect you describe would only reslult from a noise gate and compressor with more radical settings. But I hardly doubt that Dean had influence on the compressor settings. And the effect is exaclty, what is wanted in broadcasting. Ask any musician or anyone, who works with microphones, if you don't trust me!
