The Micro Converter HDMI to SDI 3G 20 Pack supplies twenty of Blackmagic Design's HDMI-to-SDI converters, each with one HDMI input and two SD/HD/3G-SDI outputs, selectable to Level A or B, supporting input/output resolutions up to 1080p60. Automatic input signal detection matches the HDMI input to the SDI output, and each unit adds SDI re-clocking and timecode support, along with embedded audio input and output. Every converter is built in a compact, rugged housing with LED video and power indicators, and is powered over USB; the pack is supplied without power supplies, so these are sourced separately for each unit.
