Video Distributor Amplifier

Posted on Posted in Uncategorized

A Video Distribution Amplifier (also known as a distribution amp or VDA) takes a video signal as an input, amplifies it, and outputs the amplified video signal to two or more outputs. It is primarily used to supply a single video signal to multiple pieces of video equipment. It adjusts the amplitude of a video signal to compensate for loss of signal in a video distribution system. Extending the distance of the video signal is the main purpose of the VDA. There are VDAs built for all video formats, NTSC, ATSC, QAM16, QAM32, QAM64, Composite Video and Component Video.

Their construction and capabilities can be simple; accept input signal, amplify, then output.
