Which device is used to switch between multiple video sources?

• A. Switcher
• B. Mixer
• C. Recorder
• D. Amplifier

Answer: (A)

Switching between multiple video sources is done with a switcher. In a video production setup, a switcher takes several video inputs—cameras, computer feeds, or media players—and sends one chosen input to the program output. It’s designed for live control, allowing the operator to cut or transition from one source to another smoothly.

The other devices aren’t built for this primary role. A mixer handles audio signals and balances levels (and sometimes blends video in some systems, but its main purpose is audio management, not routing multiple video sources). A recorder captures and stores video for later playback, not for live source selection. An amplifier boosts signal strength to displays or speakers, not for switching between inputs.
