Product Overview
The Blackmagic Design Teranex Mini HDMI to Optical 12G converts an HDMI signal to 12G-SDI, or — with an optional optical fiber module — to optical fiber, with the output automatically matching the HDMI input resolution up to DCI 4K (4096x2160) 60p. Built on Teranex video processing, it adds switchable XLR audio inputs, Ethernet control with PoE, and an intelligent thermal design for rack, desktop, or cable-duct installation. Note that the optical fiber module is not included (sold separately).
Product Description
The Teranex Mini HDMI to Optical 12G accepts an HDMI 2.0 input up to DCI 4K 60p and outputs 12G-SDI over BNC, automatically matching the HDMI input resolution. An optical fiber module can be installed in the rear SFP slot to output over fiber instead; the module is not included — 3G and 6G modules are available (ADPT-3GBI/OPT and ADPT-6GBI/OPT). Separate audio can be added via full-size XLR inputs switchable between balanced analog and AES/EBU digital, with the right XLR configurable for timecode input. A rear Ethernet port allows remote management or PoE power, and a built-in 90–240V supply means you only need a standard IEC cable (sold separately) if not using PoE. The standard front panel has mini switches for instant settings changes and can be swapped for the optional Smart Panel with a spin knob, color LCD, and six buttons to view the conversion and monitor audio and timecode. Multiple units can be managed over Ethernet from Mac or Windows using the included Converter Utility, and a smart crossflow thermal design keeps units cool when rack-mounted side by side — up to three fit in an optional 1U 19" rack tray.
