LynxTechnik yellobrik CDH1813 3Gbit SDI to HDMI Converter with 3D Support

Product Code LYCDH1813
Manufacturer LynxTechnik

Request more information or contact us now for purchasing information.


The CDH 1813 is a versatile, compact SDI to HDMI converter designed to combat a host of monitoring and display applications in Broadcast, Post Production and Pro A/V markets.

Convert any SDI video signal, including 3D into an HDMI signal for monitoring and display. Flexible fibre connectivity options add SDI fibre transmission or SDI fibre reception (or both) using the integrated fibre SFP socket.

Two channels of audio can be de-embedded from the incoming video signal providing a digital AES output and analogue audio output signals. Balanced audio outputs have selectable full scale range presets. The two selected audio channels can also be embedded into the HDMI output. In addition, 8 channels selected from the input signal (channels 1-8 or 9-16) can be embedded into the HDMI output.

All user controls are located on the top of the module clearly labelled and easily accessible. This facilitates simple changes to module function and configuration without referring to a manual. The compact portable design makes it suitable for a wide range of applications in broadcast and mobile production environments.

Various burn in features make the CDH 1813 a true monitoring tool. Timecode burn in, 16 channel audio metering, safe area markers and AFD code display are just a few of the on-screen monitoring features.
