The AJA FS2 is a professional-grade, dual-channel frame synchronizer and format converter designed to solve critical timing and compatibility issues in broadcast and live production environments. It functions as an intelligent signal processor on two independent channels, each capable of accepting a wide variety of video inputs—including SDI, HDMI, and analog component—and outputting a stable, synchronous SDI signal. Its core synchronization feature genlocks each incoming signal to an external reference, eliminating timing mismatches, frame rolls, and glitches that occur when combining feeds from unsynchronized sources, such as remote cameras, satellite feeds, or graphic servers. This is essential for clean switching, keying, and multi-viewer displays in live production.

Beyond synchronization, the FS2 is a powerful format converter. Each channel can independently scale and convert between different resolutions, standards, and color spaces, allowing seamless integration of mixed-format sources into a uniform production pipeline. For example, it can upconvert a 720p HD feed to 1080i, or downconvert a 1080p signal for an SD monitor. Housed in a compact 1RU rackmount chassis, the unit is built for reliable 24/7 operation in broadcast facilities and mobile trucks. With intuitive front-panel controls and monitoring, the AJA FS2 provides broadcast engineers with a versatile and essential tool to ensure signal stability, format compatibility, and overall technical quality in complex video systems.
