Miranda HDA-1911 3G/HD/SD distribution amplifier with EQ and reclocking - HDA-1911
The HDA-1911 and HDA-3911 are 3G/HD/SD SDI video distribution amplifiers (DAs) that support a variety of compressed and uncompressed serial digital video signals. They provide up to nine reclocked outputs with automatic 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. They offer fiber connectivity, making it ideal for longer cable lengths. Critical applications protection is provided by a protection bypass relay available on selected rears.
The HDA-1911 and HDA-3911 share the same feature set and specifications, except that HDA-1911 is a 2 RU card built for the Densité 2 frame while the HDA-3911 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.
