HDA-1951 / HDA-3951
Dual Channel 3G/HD/SD SDI Video Distribution Amplifiers
The HDA-1951 (for Densité 2 series) and HDA-3951 (for Densité 3, Densité-3+ and GV Node series) are 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-1951/3951 provides up to ten reclocked outputs with automatic inputs equalization for up to 185 meters (656 feet) of cable using Belden 1694A at 1.5 Gb/s and up to 100 meters (328 feet) at 3 Gb/s. Critical application protection is provided by optional bypass relays available on selected rears. The HDA-1951 and HDA-3951 are dual...
