Distribution Amplifier
A Distribution Amplifier, often called a DA in the broadcasting world, is a piece of equipment that takes one incoming video or audio signal and creates multiple identical copies of that signal. Think of it like a power strip, but for TV or radio signals instead of electricity. Broadcasters use these to send the same content to different places at once - like sending a TV show to multiple studios, recording devices, or transmitters simultaneously. This is essential in TV stations, radio stations, and media production facilities where the same signal needs to go to multiple places without losing quality.
