What is the purpose of 'phantom power' in a broadcast studio microphone setup?
Answer: To supply 48V DC through a balanced XLR cable to power condenser microphones
Phantom power delivers 48V DC along the balanced signal conductors of an XLR cable, providing operating voltage to condenser microphones without requiring a separate power supply.
What is the key difference between a 'cut' and a 'dissolve' transition on a production switcher?
Answer: A cut is an instantaneous transition; a dissolve is a gradual blend between two sources
A cut is an immediate frame-accurate transition between two sources with no intermediate frames, while a dissolve (mix) gradually blends from one source to another over a set duration.
In broadcast lighting, what is the 'key light'?
Answer: The primary light source illuminating the subject, setting the dominant lighting direction
The key light is the main, strongest light source in a three-point lighting setup, defining the primary illumination direction and creating the basic shadows that give a subject shape.
What is a 'chroma key' (green screen) technique used for in broadcast production?
Answer: Replacing a solid-color background with a different video source in real time
Chroma key electronically removes a specific color (typically green or blue) from a foreground image and replaces it with another video source, enabling virtual sets and weather map backgrounds.
What does 'A/B roll editing' refer to in broadcast post-production?
Answer: Alternating between two tape machines or timeline tracks to create transitions and effects between sources
A/B roll editing uses two source reels or timeline tracks (A and B) so that transitions like dissolves and wipes can be created between them, forming the foundation of non-linear editing workflows.
What is the role of a 'master control' operator in a broadcast television station?
Answer: To manage and execute the on-air broadcast schedule, including switching between live feeds, commercials, and recorded content
Master control is the nerve center of a broadcast station where operators execute the programming schedule by switching between network feeds, locally produced content, commercials, and emergency alerts.
