HDA-1941 / HDA-3941
Single Channel 3G/HD/SD SDI Video Distribution Amplifiers

The HDA-1941 (for Densité-2 series) and HDA-3941 (for Densité-3, Densité-3+ and GV Node series) are single 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. They provide up to nine reclocked outputs with automatic input 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-1941 and HDA-3941 are single channel DAs, while the complementary HDA-1951 and HDA-3951 are dual channel DAs sharing the same performance quality, but with a higher density by doubling the number of DAs per slots for projects that do not require as many outputs per DA. See the HDA-1951/3951 datasheet for more information.

  • 3G/HD/SD SDI inputs
