LYNX Yellobrik CHD 1812 HDMI to 3G SDI Converter with Frame Synchronizer
The Lynx Technik CHD 1812 is a versatile and compact HDMI to SDI converter with integrated frame synchronizer. It is an ideal solution for any application which requires a fully synchronized SDI input from an external asynchronous HDMI source. The flexible reference sync input will accept any analog video sync format including SD bi-level sync, black burst, colorbars and tri-level HD sync. The sync input is auto detecting and fully cross lock compatible. For example: An SDTV reference can be used to frequency lock an HD HDMI input. If no reference is present, the converter performs a standard asynchronous HDMI to SDI conversion. A pair of stereo analog inputs can be embedded into any AES channel. Audio inputs can be either professional balanced audio with selectable full-scale level, or unbalanced consumer line level audio. By default, any audio present in the HDMI stream will be embedded into the SDI output or it can be replaced with the external audio signals.
