Two way communication

Sameer sets up a microphone in the control room and one in the vocal booth for effective communication between the band that's listening outside while Nathan cuts his tracks in the closet. Having a talk back microphone allows the band to give immediate feedback to Nathan while allowing him to direct the engineers (Grant and Sameer) to erase and start over certain parts that he felt were weak. The talk back microphone eliminates the opening and shutting of the closet door.
