About the Evertz 7700ADA7 Analog Video Distribution Amplifier - Option Card Module
The Evertz 7700ADA7 is an analog video distribution amplifier module designed for installation in the Evertz 7700 series modular video processing platform. Its primary function is to accept a single analog video input signal—typically standard definition composite video (NTSC/PAL)—and provide multiple isolated, amplified, and equalized outputs. This is essential in broadcast and production facilities for distributing a single critical source, such as a program feed, test signal, or monitor path, to numerous destinations like monitors, routers, recording devices, or other processing equipment. The module ensures each output is a clean, buffered copy that maintains signal integrity over varying cable lengths, preventing signal degradation and loading issues that can occur when one source drives multiple inputs.
Engineered for seamless integration into a professional modular frame, the 7700ADA7 leverages the power supply, cooling, and control infrastructure of the 7700 chassis. It typically features one BNC input and seven BNC outputs (reflected in the "ADA7" designation), providing a compact, high-density 1:7 distribution solution within a single card slot. The card performs essential signal conditioning, including gain adjustment and cable equalization, to compensate for high-frequency loss. Status monitoring is typically integrated into the frame's overall management system. This modular approach allows system designers to combine multiple DAs and other signal processing functions in one centralized, rack-mounted unit, optimizing space and reliability.
As a component of the robust 7700 platform, the 7700ADA7 offers a dependable and efficient solution for distributing legacy analog video signals in mission-critical broadcast and AV environments. It is commonly deployed in master control rooms, mobile production trucks, and post-production facilities where analog sources must be maintained within a modern, predominantly digital infrastructure. By providing clean, amplified signal copies from within a reliable modular system, it helps ensure the continued operation and signal quality of essential analog video paths.
