The Evertz 7812XC-AES8-3G +DD is a professional broadcast-grade audio processing and embedding module designed for integration into the Evertz 7800 series modular frame system. This advanced unit functions as a high-density cross converter, specializing in the critical task of managing and converting Dolby Digital audio formats within a 3G/HD-SDI video environment. Its primary role is to encode, decode, and transcode Dolby Digital (AC-3) and Dolby Digital Plus (E-AC-3) bitstreams, while simultaneously handling up to eight channels of AES3 digital audio. It seamlessly embeds these processed audio streams into the serial digital interface signal, ensuring perfect synchronization and compliance with stringent delivery specifications for television broadcast and digital distribution.

This module is engineered for complex audio workflows found in master control, playout, and network transmission centers. It can up-convert legacy audio formats like Dolby E or PCM into a broadcast-ready Dolby Digital stream, or down-convert incoming Dolby Digital for monitoring and routing. The unit's certified Dolby processing ensures accurate metadata handling, including dialnorm adjustment, which is essential for maintaining consistent audio loudness levels across programming. Configuration and real-time monitoring are achieved through the centralized frame management software, providing comprehensive control over audio mapping, levels, and processing parameters for all installed modules from a single interface.

Built for maximum reliability in 24/7 operations, the module supports automatic format detection and seamless pass-through of video and ancillary data. Its design within the 7800FR frame with a 3RU backplane provides redundant power and cooling, making it a scalable and robust solution for facilities that require guaranteed performance, high channel density, and streamlined management for their critical audio-video infrastructure.
