Introduction
The VOPEX®4-Port 3G-SDI Splitter simultaneously displays the same image from one SD/HD/3G-SDI video source onto
four SD/HD/3G-SDI monitors.
Features
Simultaneously broadcasts 3G-SDI/HD-SDI/SD-SDI signal from one source to four displays using 75 Ohm RG6
BNC cables.
oAutomatic input equalization –compensates for attenuation on the incoming signal and automatically
equalizes cables for the following distances:
3G-SDI 1920x1080@60Hz to 328 feet (100 meters).
HD-SDI 1280x720@60Hz to 656 feet (200 meters).
SD-SDI 525i@60Hz and 625i@50Hz to 984 feet (300 meters).
oAutomatic output reclocking –reshapes and restores timing of digital video signals at output, eliminating
high frequency jitter.
Supports HDTV resolutions to 1080p @60Hz.
Auto-detects 3G-SDI, HD-SDI, or SD-SDI format.
oSupports 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.
Passes embedded audio, ancillary ID and metadata information, and SD/HD/3G-SDI digital video signals
oSupports 48kHz audio.
Plug-and-play functionality –no software needed.
Ideal for CCTV surveillance systems, TV broadcast studios, digital cinema, medical imaging facilities, or any AV
application where signals need to be split from a camera or other device equipped with 3G/HD/SD-SDI outputs to
four SDI-compliant displays or video processors.
