Switches to preset the zoom of a camera in a studio are called:

(A) switch box

(B) cable box

(C) central box

(D) shot box

Correct Ans: (D)

Explanation:
Operators use shot boxes to control the preset zoom of cameras in a studio. This lets them set the camera’s zoom and focus, ensuring smooth transitions between shots during live broadcasts or productions. The shot box helps operators maintain the correct framing and focus as they switch between different scenes or angles.

Other options, like switch boxes, cable boxes, and central boxes, don’t perform this function. Operators use a switch box to change video feeds and select which video source to display on the screen, but it doesn’t control the camera’s zoom or focus. A cable box decodes television signals to give viewers access to cable channels, but it doesn’t control the camera or production equipment. Similarly, a central box doesn’t manage camera zoom control. While operators may use it to manage other equipment, it doesn’t control the camera’s zoom.
