The M-HH Converter is part of the Digital Forecast Bridge M Series (Micro Type Converters). The M-HH converts HDMI signals to SMPTE standard SDI signals, supporting formats up to 1080p60, for use in professional A/V settings. Additionally, this converter allows you to mux your analog audio signal into your outgoing SDI video signal if necessary, as well as fix the SDI output to a specific format using the built-in scaler. The HDMI output is also capable of being scaled. This converter includes a USB input and a 3.5mm stereo analog audio input.
