The AJA HI5-12G is a professional-grade, high-performance signal converter designed to bridge the gap between professional SDI broadcast workflows and modern HDMI 2.0 displays. Its primary function is to take a 12G-SDI input signal and convert it to an HDMI 2.0b output with pristine image fidelity and minimal latency. This device is engineered for applications where a high-quality monitoring connection is critical, such as in broadcast control rooms, production trucks, post-production suites, and live event setups. It effectively connects professional 4K cameras, routers, or servers using 12G-SDI outputs to consumer or prosumer-grade UltraHD monitors and televisions, enabling cost-effective yet reliable video monitoring.

A key strength of the HI5-12G is its exceptional format flexibility and support for high-performance video standards. The converter can handle an extensive range of video formats, from standard definition up to 4K and UltraHD resolutions at high frame rates of up to 60 frames per second. It fully supports High Dynamic Range workflows, generating HDR10 metadata and supporting the HLG (Hybrid Log-Gamma) standard in compliance with HDMI v2.0b and CTA-861-G specifications. This ensures that the full richness of color, luminance, and detail from HDR camera sources is accurately passed through to compatible displays, making it a valuable tool for productions utilizing this technology.

Beyond video, the converter provides comprehensive and versatile audio handling. It supports up to 16 channels of 24-bit embedded audio on the SDI input, passing through up to 8 channels to the HDMI output. Additionally, it features dedicated 2-channel analog RCA audio outputs for independent audio monitoring without the need for an external de-embedder. For system configuration and monitoring, a USB port allows the unit to be connected to a computer using AJA's free Mini-Config software, enabling detailed status viewing, parameter adjustment, and firmware updates. The compact, portable design, combined with a robust five-year warranty, makes the HI5-12G a reliable and essential tool for modern, multi-format professional video environments.
