The HDA-1951 for Densite-2 series is dual channel 3G/HD/SD SDI video distribution amplifiers designed for broadcast and production facilities. The two cards are functionally identical, supporting a variety of compressed and uncompressed serial digital video signals, with up to dual 1x5 outputs. The HDA-1951 provides up to ten re-clocked outputs with automatic inputs equalization for up to 200 meters (656 feet) of cable using Belden 1694A at 1.5Gbps and up to 100 meters (328 feet) at 3Gbps. Critical application protection is provided by optional bypass relays available on selected rears. The HDA-1951 is dual channel DAs, while the complementary HDA-1941 and HDA-3941 is single channel DAs sharing the same performance quality, but with a lower density and more outputs per DA.
