Miranda HDA-1931 Dual 3G/HD/SD distribution amplifier with EQ and reclocking - HDA-1931
The HDA-1931 and HDA-3931 are dual 3G/HD/SD SDI video distribution amplifiers (DAs) that support a variety of compressed and uncompressed serial digital video signals. They provide up to eight reclocked outputs with automatic equalization for up to 150 meters (492 feet) of cable using Belden 1694A at 1.5Gb/s and up to 90 meters (295 feet) at 3 Gb/s, and offer fiber connectivity, making it ideal for longer cable lengths.
The HDA-1931 and HDA-3931 share the same feature set and specifications, except that HDA-1931 is a 2 RU card built for the Densité 2 frame while the HDA-3931 is a 3 RU card made for the Densité 3 frame series. Each product has its specific rears as illustrated in the Key Features section and in the ordering information.
