About the Evertz 500A-3G 3G/HD/SD-SDI Reclocking Distribution Amplifier
The Evertz 500A-3G is a high-performance, single-slot distribution amplifier card designed for the critical task of signal integrity management within professional broadcast and video production infrastructures. It is engineered to accept a single 3G-SDI, HD-SDI, or SD-SDI input and regenerate multiple pristine, identical outputs, effectively mitigating signal degradation that occurs over distance or through multiple connections. This unit functions as an essential tool for fanning out a master video source to numerous destinations such as monitors, routers, recording servers, and transmission encoders while ensuring each output maintains precise timing, correct voltage levels, and minimal jitter. Its primary value lies in its ability to act as a signal rejuvenator, re-clocking the data stream to a stable reference, which is fundamental for maintaining picture quality and preventing synchronization errors in a facility.
Constructed with advanced signal processing circuitry, the card excels at restoring the integrity of serial digital video feeds. The re-clocking process involves extracting the embedded clock from the incoming signal, cleaning it of accumulated timing imperfections (jitter), and then using this stabilized clock to retransmit the video data. This results in outputs that are electrically superior to the potentially degraded input, extending the operational cable length and improving the reliability of the entire signal chain. The device is fully automatic, seamlessly detecting and processing the incoming data rate from standard definition up to 3 Gbps, which encompasses 1080p high-definition formats, without the need for manual switching or configuration.
Designed for integration into the manufacturer's modular and scalable 500 series frames, the card benefits from the chassis's redundant power supplies and centralized control. It offers straightforward monitoring through front-panel LED indicators that display signal presence and status for each channel. This combination of robust signal conditioning, operational simplicity, and rack-mount reliability makes the 500A-3G a ubiquitous and trusted component in broadcast centers, post-production suites, and live event facilities. It provides a foundational layer of signal assurance, ensuring that video content is distributed flawlessly throughout a complex technical operation.
