The Atlona AT-3GSDI-HD2 is a compact, professional-grade format converter designed to bridge professional SDI video workflows with consumer and prosumer HDMI displays. It accepts high-quality digital video signals via a 3G-SDI, HD-SDI, or SD-SDI input and converts them to a pristine HDMI output, complete with embedded stereo audio. This device is essential in broadcast, live production, post-production, and presentation environments where signals from professional cameras, switchers, routers, or servers need to be monitored or displayed on HDMI-based monitors, projectors, or large-screen TVs. The converter supports a wide range of SDI standards, making it versatile for handling everything from standard definition content up to 1080p60 high-definition signals, ensuring compatibility with both legacy and modern equipment.

The converter is engineered for reliability and simplicity, featuring a robust, compact metal housing and requiring no configuration or external power when utilizing the optional phantom power feature. A key professional feature is its ability to be powered directly from the SDI input source (via +12V phantom power on pins 2 & 3 of the BNC connector), eliminating the need for an external power adapter in many setups and simplifying installations. It includes high-quality scaling to ensure the output HDMI signal matches the optimal resolution for the connected display, even if it differs from the SDI input resolution. By providing a straightforward, high-fidelity conversion path from SDI to HDMI with embedded audio, the AT-3GSDI-HD2 serves as a critical interface tool for video engineers, technicians, and content creators who need to integrate professional video sources into consumer display ecosystems.
