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 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-1941 and HDA-3941 are single channel DAs, while the complementary HDA-1951...
