An HDMI source up to Full 4K DCI 4096x2160p resolution goes in, and up to two 12G-SDI outputs at the same resolution come out on the Teranex Mini HDMI to SDI 12G Converter — built for rack-mount, cable-duct or desktop installation with intelligent heat dissipation. XLR connections are switchable to AES/EBU, and an Ethernet port handles remote control or PoE power. Multiple units can be managed from a single Mac or PC, with up to three fitting in a 19-inch rack.
