Key Features
The Extron SW4 12G HD‑SDI is a four-input, two-output 12G‑SDI switcher. It switches multi-rate SDI video, embedded audio, and other ancillary data between four source devices and delivers simultaneous output signals to a pair of SDI displays or sink devices. The SW4 12G HD‑SDI supports video resolutions up to 4K/60, HDR, and data rates up to 11.88 Gbps, including all common serial digital video data rates specified by SMPTE and ITU standards. To ensure signal integrity over long cable runs, the switcher features automatic input cable equalization and output reclocking. The SW4 12G HD‑SDI offers RS‑232, front panel, and auto-input switching control options, allowing integration into a variety of applications and environments.
