This advanced device, the flagship offering from AJA, delivers unparalleled versatility and connectivity in a compact 1RU frame, making it an essential tool for all your conversion needs. The FS4 is a 4-Channel 2K/HD/SD or 1-Channel 4K/UltraHD frame synchronizer and up, down, cross-converter. It provides a broad spectrum of connection options for both video and audio, allowing it to replace four separate devices in 2K/HD/SD or combine all processors and channels for maximum 4K/UltraHD productivity. In Single Channel mode, the FS4 offers a comprehensive suite of 4K/UltraHD processing and up, down, cross-conversion to and from 2K, HD, or SD. In Four Channel mode, it delivers 4 x 2K/HD/SD channels of simultaneous conversion and processing within a sleek 1RU chassis, ideal for high-density multi-channel delivery. The FS4 is equipped with a wealth of digital video connectivity options, including Quad 1.5G, Dual 3G, Quad 3G over 3G-SDI, and 12Gb/6Gb over optional 12G-SDI BNC and 12G-SDI LC Fiber SFP modules. In single channel mode, it can upscale your HD or SD materials to 4K/UltraHD and back, supporting an impressive 272 x 208 matrix of audio channels over Fiber, 3G-SDI, AES, and MADI. In four channel mode, the FS4 provides powerful multi-channel conversion with up to 4 channels of simultaneous processing for 2K/HD and SD signals. This includes Region of Interest (ROI) scaling, color correction, proc amp controls, motion adaptive deinterlacing, and more. The FS4's front panel has been redesigned for easy access to its rich feature set. It offers straightforward operation in single channel or four channel mode, with clear indicators for each mode. The FS4 supports up, down, cross-conversion from SD, HD, or 2K over 12G/6G/3G-SDI video to 4K or UltraHD video and back, using AJA's superior conversion algorithms. Both Quadrant (Square Division) and 2SI (Two Sample Interleave) output formats are supported, ensuring the highest image quality for your productions. The FS4 offers incredible digital connectivity for video and audio, integrating easily into a variety of workflows and facilities with support for SDI workflows up to 12G. It has BNC and Fiber inputs and outputs to accept 4K/UltraHD/2K/HD/SD resolution SDI signals in Single Channel Mode. In Four Channel mode, 2K/HD/SD inputs can be routed to multiple locations simultaneously without the need for external signal distribution. The FS4 supports closed captioning and the conversion of closed captioning between 2K/HD/SD and 4K/UltraHD formats, including full conversion of CEA-608 and CEA-708 standards. It can preserve closed captioning even when converting between formats, eliminating the need to re-insert closed captions after conversion. FS4 is network ready and supports SNMP monitoring and web-based remote control. Units can be connected to any Ethernet network via the built-in 10/100/1000MB Ethernet port, allowing control and configuration of multiple FS units from any web browser on a connected computer. Configurations can be saved and applied to multiple units, ensuring consistency and quick configuration in large installs. In summary, the FS4 1RU Frame Synchronizer and Converter is a powerful, versatile, and reliable solution for your 4K/UltraHD and multi-channel 2K/HD/SD workflows.
