MSA6800+B4D, +C4D

4-Channel AES Embedder with Synchronizer

The MSA6800+B4D/+C4D series of analog audio embedders/synchronizers for the 6800+™ core processing platform accepts a serial digital video input and embeds four AES signals into the SDI signal. Each module provides three SDI outputs containing the embedded audio. The two-input modules also provide two AES outputs for general-purpose use.

Part of the 6800+ platform, these modules are optimized to provide automatic audio delay tracking when used with the DES6800+ decoder/synchronizer or HFS6801+ or VFS6800+ frame synchronizers, compensating for video delay in the video processing modules. When the data I/O signal is externally connected between these video and audio modules, audio in the embedder is automatically delayed to track the video to maintain lip sync. This configuration also allows passing or muting of the audio when the video input is disrupted.

The MSA6800+ modules can be controlled manually via card-edge controls, or controlled and monitored via the CCS Navigator™ software application, HTTP web browser, NUCLEUS™ hardware control panels or third-party SNMP-based control applications.
