The Barco R9004623, also known as the FSN-150 Compact Controller, is a dedicated hardware control surface for the Barco FSN series video production switchers. It is designed to provide tactile, hands-on control for live video switching, routing, and effects in broadcast, live event, and production truck environments. The compact controller offers a subset of the full FSN system's functionality in a more space-efficient package, making it ideal for smaller control rooms, mobile units, or as a secondary panel for a technical director or assistant. Its interface is laid out to mirror the software interface of the FSN system, providing immediate access to critical functions without needing to navigate on-screen menus.

The unit features a range of physical controls including dedicated buttons for selecting video sources (inputs), assigning them to program and preview buses, and executing transitions with adjustable rates. It includes a central joystick for controlling Digital Video Effects (DVE) like picture-in-picture positioning, as well as dedicated keys for common functions like cuts, fades, and auto-transitions. The controller integrates seamlessly with the main FSN frame, allowing operators to build muscle memory and work more efficiently during fast-paced live productions compared to using a mouse and keyboard alone.

Built with the durability required for 24/7 broadcast operations, the FSN-150 Compact Controller connects to the FSN frame via a standard network cable. Its design focuses on ergonomics and workflow efficiency, placing the most frequently used commands at the operator's fingertips. By offering dedicated physical controls in a compact form factor, this controller enhances operator speed, precision, and confidence when driving a Barco FSN video switcher.
