The Micro Converter Bidirectional SDI/HDMI 3G 20 Pack supplies twenty of Blackmagic Design's bidirectional SDI/HDMI converters, each able to convert SDI to HDMI and HDMI to SDI at the same time, even across different standards on each side, up to DCI 2K in SDI and 1080p60 in HDMI. Camera control conversion lets a Blackmagic HDMI camera such as the BMPCC 4K or 6K work with an SDI-based live switcher, with tally support included. Every unit adds HDMI timecode support, SDI re-clocking for stable long cable runs, support for pro broadcast resolutions including cine-style 48 fps, and both HDMI and SDI embedded audio input and output. Each converter is housed in a sturdy metal shell with rugged connectors and LED video and power indicators, and its USB Type-C port powers the unit and provides setup and firmware access from a Mac or Windows computer; the pack is supplied without power supplies, though each unit can also run from a separately available 100-240 VAC supply with four international socket adapters.
