The Teranex Mini HDMI to SDI 12G Converter, from Blackmagic Design, is a highly improved solution for rack-mount as well as cable duct and desktop installations. Connect an HDMI signal in up to Full 4K DCI 4096x2160p resolution and route it out over up to two independent 12G-SDI outputs in the same resolution. Route 4096x2160p signals approximately 70 ft using 6G-SDI cables, and run lower-resolution signals, such as 3G-SDI or HD-SDI, for much longer than standard lengths. When 12G-SDI cables will be available on the market, you'll be able to run 4K DCI 4096x2160p signals for over 250 ft. You can also connect separate audio via full-size XLR inputs that are switchable between balanced analog and AES/EBU digital audio.
