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 200 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 channel DAs, while the complementary HDA-1941 and HDA-3941 are single channel DAs sharing the same performance quality, but with a lower density and more outputs per DA. See the HDA-1941/3941 datasheet for more information.

  • Dual 3G/HD/SD SDI inputs
  • Supports bit-rates up to 2.97 Gb/s
  • Automatic format detection and cable equalization
  • All outputs are DVB-ASI compatible
  • Up to 8 3G/HD/SD SDI outputs on the HDA-1951 (2 RU)
  • Up to 10 3G/HD/SD SDI outputs on the HDA-3951 (3 RU)
