Distribution Amp.

Typically referring to video and audio/video (A/V), a distribution amplifier (DA, also called a splitter) is a device that takes one video (or A/V) input signal, amplifies it and simultaneously sends it to multiple outputs, with each destination receiving the same signal.

The signal source could be a DVD player, a set top box, or any other video or audio/video source. The multiple outputs would typically be video screens.

In effect, a distribution amplifier duplicates the input signal (from the source) and displays it as identical video on multiple displays.

Distribution amplifiers (DAs) may support the target destinations being in proximity to the source, or being far away from the source, typically using CAT-5 cable as means of connecting the source to the destination.
