The VOPEX-3GSDI-4 broadcasts a 3G-SDI/HD-SDI/SD-SDI signal from one source to four displays using 75 Ohm RG6 BNC cables. It supports automatic input equalization, which compensates for attenuation on the incoming signal and automatically equalizes cables for the following distances: 3G-SDI 1920x1080 at 60Hz to 328 ft (100 m), HD-SDI 1280x720 at 60Hz to 656 ft (200 m), and SD-SDI 525i at 60Hz and 625i at 50Hz to 984 ft (300 m). In addition, it features automatic output reclocking, which reshapes and restores timing of digital video signals at output, eliminating high frequency jitter.
The 3GSDI Distribution Amplifier passes embedded audio, ancillary ID and metadata information, and SD/HD/3G-SDI digital video signals. It supports HDTV resolutions to 1080p at 60Hz; auto-detects 3G-SDI, HD-SDI, or SD-SDI format; and is compatible with SMPTE 259M, SMPTE 292M, SMPTE 296M, SMPTE 424M, SMPTE 425M Level A, and ITU-R BT.656/BT.601 video interfaces used for broadcast-grade video.
