yellobrik CHD 1812-1 HDMI to SDI Converter with Frame Synchronizer

The yellobrik CHD 1812-1 by LYNX Technik is a compact, professional-grade HDMI to SDI converter with an integrated frame synchronizer. It supports SDI video formats up to 3G-SDI (1080p60), providing seamless integration for broadcast, post-production, and pro AV workflows. With advanced features like cross-lock compatible sync inputs and external audio embedding, the CHD 1812-1 ensures reliable performance and flexibility for demanding environments.

Key Features:

• Video Conversion: Converts HDMI signals up to 3G-SDI (1080p60) with 3D and Level A/Level B support.
• Integrated Frame Synchronizer: Synchronizes asynchronous HDMI inputs to SDI outputs, with adjustable delay in frame, pixel, and line increments.
• Multi-Format Sync Input: Accepts SD and HD analog sync signals, including bi-level sync, black burst, and tri-level sync, with cross-lock compatibility.
• Audio Options: Supports transparent pass-through of HDMI embedded audio or embeds external analog audio into selectable AES channels.
• Dual SDI Outputs: Includes two identical SDI outputs (not dual link) and optional optical SDI output via plug-in SFP modules.
• Advanced Monitoring: LED indicators for HDMI, audio, and sync status.

Specifications:

• HDMI Input: Type A connector, 3D-compatible, with up to 8 channels of embedded audio.
