Bridging configurable distribution amplifier (D/A). Four independent 1 x 4 D/A's are integrated within the 3RU chassis. What makes the RGB-144 unique is the ability to bridge adjacent 1x4 blocks to make a larger D/A. In default configuration, the RGB-144's four 1x4 D/A's operate independently. By simply flipping the bridge switches, adjacent 1x4 D/A's are bridged together and the input of the first block is sent to all of the bridged outputs allowing many different configurations to suit your signal distribution needs.
