Maintains clean, noise-free signal to projector or flat panel device over significant distance. Video and computer signal range is limited to few dozen feet -- even with heavily shielded cables -- before signal degredation becomes noticeable. Distribution amp may be needed for shorter distances when wiring passes by or across electrical conduits -- especially with ceiling mounting. Distribution amp may be able to split and amplify signal to drive multiple projectors, flat panels.canonglossaryus
Increases audio or video signal and distributes to multiple outputs, i.e. video monitors, recording devices. Maintains original signal s output impedance, avoiding mismatches, reducing power required to properly drive signal s end point.
