CHD 1402

HDMI to 12G-SDI Converter

The CHD 1402 is a compact HDMI to 12G-SDI converter. It is an ideal solution for any application which requires a broadcast quality 12G-SDI signal derived from an external HDMI source. The PCM audio present in the HDMI stream will be embedded into the corresponding channels on the SDI output.

A 12G-SDI fiber output is provided with a selection of optional SFPs.

Note: For legal reasons, HDMI capture devices from LYNX Technik AG are designed not to capture, convert or transmit video or audio from HDCP copy-protected sources (e.g. Satellite receivers, Cable receivers, etc.).

The module is fully compatible with yelloGUI and LynxCentraal. It can be configured, controlled and updated using Windows or MacOS.
