The Evertz 7701FR is a multi-slot modular chassis designed as the foundational frame for the Evertz 7700 series signal management and processing platform. It serves as a scalable enclosure that houses and powers a variety of specialized cards for routing, processing, and monitoring video, audio, and data signals in professional broadcast, cable, and telecom facilities. The chassis is engineered for high-density, high-availability applications where reliability, redundancy, and serviceability are critical for 24/7 operation. Its robust metal construction includes redundant, hot-swappable power supplies and cooling fans, minimizing single points of failure and allowing for maintenance without taking the system offline.

The modular design of the 7701FR allows system integrators to populate its slots with a diverse selection of Evertz 7700 series modules. These can include input/output cards for various signal types (SDI, AES, ASI, IP), processing cards (frame synchronizers, embedders, converters), and monitoring/control cards. This enables the creation of a customized signal management system tailored to specific workflows, such as master control switching, satellite receive, playout distribution, or quality assurance. The chassis features a high-speed backplane for low-latency communication between cards and supports comprehensive remote management via Ethernet for monitoring and control through Evertz's software platforms.

As the central infrastructure component of the 7700 series, the 7701FR Multiframe provides the physical and electrical backbone for building reliable, scalable signal management solutions. Its emphasis on modularity, redundancy, and centralized control makes it suitable for mission-critical environments where signal integrity and uptime are non-negotiable. By offering a standardized, expandable platform, it enables facilities to adapt their technical plant to evolving standards and requirements without replacing core infrastructure.
