## Long description

AJA FS4 is an active video signal converter and frame synchronizer supporting up to 4096×2160 resolution with BNC input and output interfaces. Housed in a 1U rack frame and rated for 100–240 V, 50/60 Hz power, the unit provides single-channel 4K/UltraHD processing or four simultaneous 2K/HD/SD channels. FS4 performs real-time up, down and cross-conversion between SD, HD, 2K and 4K/UltraHD and offers a wide range of digital connectivity options including BNC SDI and optional 12G-SDI fiber or 12G-SDI BNC SFP modules. The converter also supports extensive audio routing, closed captioning conversion and remote control via Ethernet.
Advantages
FS4 combines multi-channel conversion and frame synchronization in a compact 1RU chassis, reducing rack space while providing flexible routing and high-quality format conversion. The unit supports both single-channel 4K/UltraHD workflows and four-channel 2K/HD/SD operation, enabling broadcasters and production facilities to adapt to mixed-resolution environments. Built-in audio handling and closed captioning conversion preserve ancillary data during format changes, and network control plus SNMP provides centralized management and remote configuration.
Suitable for
Broadcast and television signal conversion and routing
Live production and outside broadcast trucks
Post‑production facilities and grading suites requiring format conversion
Mobile production, event staging and rental houses needing dense multi-channel processing

Form factor: 1U rack-mount chassis
How to use
Install the FS4 in a standard 19-inch rack occupying one U of rack space and connect power to a 100–240 V AC supply. Use BNC SDI connections or optional SFP/fiber modules to connect video sources and destinations. Select single-channel or four-channel mode via the front panel or the web interface depending on your workflow needs. Configure input/output formats, conversion type (up/down/cross) and audio routing through the on-device menus or remotely via the built‑in web control. Lock the unit to house sync by connecting the reference input when required.
Usage recommendations
For mixed-resolution environments, use single-channel mode when you require 4K/UltraHD upscaling or downscaling with full audio and ancillary data preservation. Use four-channel mode to maximize density for multi-camera HD/SD operations. Enable network management and save configuration templates for rapid deployment across multiple units in larger installations.
