The MD-LX is a pocket-sized bidirectional converter with an HDMI input and output on one side and a 3G/HD/SD-SDI input and output on the other, supporting resolutions up to Full HD 1080p60. It offers multiple input/output conversion modes, including simultaneous SDI-to-HDMI and HDMI-to-SDI conversion when both inputs are active, plus 3G level A/B conversion. A USB port handles power, control and firmware upgrades, and both the HDMI and SDI inputs have physical locks.
