The Teranex Mini Quad SDI to 12G-SDI converts four-cable Quad Link Ultra HD signals down to a single 12G-SDI BNC cable, letting older Quad Link cameras and equipment connect into a modern 12G-SDI router, switcher, or projector. It's aimed at facilities transitioning from Quad Link infrastructure who don't want to replace still-functional Quad Link gear all at once. Supporting both Level A and Level B 3G-SDI keeps it compatible with a wider range of existing equipment during that transition. Converts Quad Link SDI to single 12G-SDI: Replaces four BNC cables with one for connecting to modern 12G-SDI infrastructure. Supports Level A and Level B 3G-SDI: Compatible with a wider range of existing Quad Link equipment. Automatic multi-rate switching: Auto-switches between SD, HD, 2K, and 4K formats on each of the four inputs. SDI re-clocking: Regenerates the signal for optimal quality over long cable runs. PoE+ powered option: Can run on 48V DC via Power over Ethernet in addition to standard AC power. 3-year limited warranty: Backed by Blackmagic's manufacturer warranty, with software updates via USB or Ethernet.
