Sound Department

The department head and the person ultimately responsible for all sound recorded on set. The mixer operates the recording equipment, sets levels, monitors quality in real-time, selects microphone placements, and manages wireless frequencies. They sit at the sound cart with headphones on, hearing everything -- including problems nobody else notices.

Holds and positions the boom microphone to capture dialogue from the optimal position -- as close to the actors as possible without entering the frame. This requires extraordinary arm strength, spatial awareness, knowledge of frame lines, and the ability to anticipate actors' movements. A great boom op is part athlete, part mind reader.

The third member of the sound team. Handles wireless microphone placement on actors (often requiring intimate body mic placement), manages cable runs, operates playback equipment, handles IFB distribution to producers and directors, and assists with any sound department need.

Operates equipment to play pre-recorded music or sound effects on set -- for musical performances, dance sequences, or any scene requiring actors to react to specific audio. Manages speakers, monitors, and synchronization with picture.
