AJA FS4: The Ultimate 4K/HD Frame Synchronizer & Converter
Bridge the gap between formats and future-proof your workflow with the AJA FS4, a flagship frame synchronizer and converter designed for the demanding broadcast and production environments of today and tomorrow. Housed in a sleek and power-efficient 1RU chassis, the FS4 offers unprecedented versatility, acting as four separate devices in one. Whether you're managing a multi-camera 2K/HD production or mastering a 4K/UHD project, the FS4 adapts to your needs with its powerful dual-mode operation.
In Four-Channel mode, the FS4 provides high-density processing for up to four independent 2K/HD/SD signals simultaneously, making it the perfect hub for complex live events and multi-source ingest. Switch to Single-Channel mode to unlock the full power of its processing for 4K/UHD workflows. Effortlessly up, down, and cross-convert between any format—from legacy SD to pristine 4K—using AJA’s renowned 10-bit conversion algorithms, ensuring your images retain the highest possible quality. The FS4 preserves critical data, including closed captions (CEA-608/708) and Active Format Description (AFD), eliminating the need for downstream fixes.
Connectivity is at the core of the FS4's design. It features a wealth of digital I/O, including standard BNC connections and optional SFP modules for 12G-SDI over fiber or HD-BNC, allowing for cable runs up to 10km. Audio management is equally robust, with a massive 277x208 audio matrix that lets you route, mix, embed, and dis-embed audio between SDI, MADI, and AES sources with complete freedom. Control is simple and intuitive, either through the redesigned front panel or remotely via any web browser on the network, making configuration and monitoring of multiple units a breeze. The AJA FS4 isn't just a converter; it's the central nervous system for your multi-format video infrastructure.
