Discover the Lynx Technik yellobrik CHD 1812, a high-quality HDMI to 3Gbit SDI converter renowned for its durability and innovative design. This user-friendly device is the perfect solution for professionals seeking a reliable way to convert HDMI signals into fully synchronized SDI inputs. The CHD 1812 stands out in the market for its integrated frame synchronizer and analog audio embedder, ensuring that your video and audio remain perfectly in sync during conversion.
The CHD 1812's frame synchronizer is adept at handling asynchronous HDMI sources, providing a seamless conversion experience. Its flexible reference sync input is compatible with a wide range of analog video sync formats, including SD bi-level sync, black burst, color bars, and tri-level HD sync. With its intelligent auto-detecting capabilities, the CHD 1812 can cross lock different standards, ensuring that even if you're using an SDTV reference, it can frequency lock an HD HDMI input with precision.
In the absence of a reference signal, the CHD 1812 performs a standard asynchronous conversion, maintaining the integrity of your media. For audio, the converter allows for the embedding of stereo analog inputs into any AES channel, catering to both professional balanced audio with selectable full-scale levels and unbalanced consumer line-level audio. The default setting ensures that any audio present in the HDMI stream is embedded into the SDI output, but it can also be replaced with external audio signals if required.
The CHD 1812 is also compatible with the yelloGUI software package, which offers access to a plethora of internal settings, including adjustable video delay for precise timing adjustments. Additionally, the module provides an SDI fiber output, with a variety of plug-in SFP options available to suit your specific needs.
The SDI output resolution is intelligently selected based on the HDMI input resolution, and while the module does not include an internal scaler, it automatically selects the closest SDI standard to match the input, ensuring minimal image cropping or boxing. The frame synchronizer is fully cross lock compatible, capable of dropping or adding frames to produce a correctly synchronized SDI output with frame rate conversion.
Key features of the CHD 1812 include:
- Support for SD/HD/3G-SDI formats
- 3D support for advanced video requirements
- Multi-format sync reference input for versatile cross lock compatibility
- Dual SDI outputs with an optional SDI fiber output for extended connectivity
- Transparent passage of HDMI embedded audio
- Two external analog audio inputs for comprehensive audio embedding
- Choice of professional balanced analog audio inputs or unbalanced line-level audio inputs
- Selectable AES channel for embedding external audio with precision
- LED indicators for HDMI, reference, and audio signals
- yelloGUI compatibility for advanced internal setting adjustments
Choose the yellobrik CHD 1812 for its unparalleled performance in synchronizing and embedding audio in your video conversions, backed by the reputable Lynx Technik brand.
