The Evertz 7800FR-QT is a rack-mountable multi-frame chassis designed to house and power a large array of modular signal processing, routing, and interface cards from Evertz's extensive 7800 and 7700 series. This frame serves as the foundational hardware platform for building high-density, centralized signal management systems in broadcast facilities, teleports, and data centers. The "QT" designation typically refers to its "Quad Transport" capability or a specific high-capacity backplane architecture, indicating it is engineered to support a mix of high-bandwidth cards for video, audio, and data transport, including those handling 12G-SDI, 4K, IP (SMPTE ST 2110), and optical signals. It provides the essential infrastructure—power, cooling, control, and card interconnection—required for mission-critical, 24/7 broadcast operations.

The frame is engineered for maximum reliability and serviceability. It features fully redundant, hot-swappable power supply units (PSUs) and cooling fan trays, ensuring uninterrupted operation even if a single component fails. The advanced backplane provides high-speed data pathways between cards and integrates system control and monitoring functions. A dedicated system controller within the frame (or as a separate card) manages the entire chassis, offering comprehensive remote management via a web-based graphical user interface (GUI), SNMP, and support for industry standards like Ember+. This allows engineers to monitor the health of every card, view real-time signal status, configure parameters, and receive alarms from a single point of control.

Designed for scalability, the 7800FR-QT can be populated with a wide variety of cards to create customized solutions for frame synchronization, format conversion, audio processing, signal distribution, IP gateway functions, and more. Its modular nature allows facilities to start with a core set of functions and expand over time without replacing the underlying infrastructure. The robust steel construction and efficient thermal design ensure stable operation even when fully loaded. As the core of a modular broadcast system, the Evertz 7800FR-QT multi-frame provides the necessary reliability, density, and management capabilities to handle the complex and evolving signal workflows of a modern media facility.
