The Evertz 7746FS-EAES8-HD is a professional high-definition frame synchronizer module with integrated embedded audio processing, designed for the Evertz 7700 series modular platform. Its primary function is to accept an asynchronous or unstable HD-SDI video input, synchronize it to a local, stable reference signal (genlock), and output a perfectly timed, broadcast-quality HD-SDI signal. This process is critical in broadcast environments where video sources—such as satellite feeds, remote cameras, or legacy playback devices—arrive with timing that does not match the facility's master clock. The frame synchronizer eliminates timing differences, preventing glitches, rolls, and tears when switching between sources.

A key feature of this specific module is its advanced embedded audio processing ("EAES8" indicates 8 channels of embedded audio extraction and re-embedding). It can extract the audio tracks embedded within the incoming HD-SDI stream, allowing for independent audio processing—such as level adjustment, delay for lip-sync correction, or format conversion—before seamlessly re-embedding them into the synchronized video output. This integrated audio-video processing ensures perfect synchronization between picture and sound, which is a fundamental requirement for professional broadcasting. The module integrates into the 7700 chassis, leveraging its power, cooling, and management system for remote control and monitoring via Evertz software.

As a mission-critical component in master control, production, and routing facilities, the 7746FS-EAES8-HD ensures signal integrity and operational reliability. It enables the seamless integration of diverse external sources into a synchronized broadcast chain, handling both the video timing and complex audio relationships. By providing frame synchronization and sophisticated audio processing in a single, high-density module, it streamlines signal path design and enhances the stability of the entire on-air presentation.
