VAM6800+A4D
Digital-to-Analog Monitoring Encoder/Converter
The VAM6800+A4D module is a digital-to-analog encoder/converter for video and audio monitoring. Part of the 6800+™ core processing platform, the module accepts one SD-SDI input with embedded audio and converts into a composite analog output (NTSC, PAL-B, or PAL-M) and 4 analog audio outputs. Video and audio processing capabilities exist via integrated video and audio processors.
The VAM6800+A4D module can be controlled manually via card-edge controls, or controlled and monitored via the CCS Navigator™ software applications, HTTP web browser, NUCLEUS™ hardware control panels or third-party SNMP-based control applications. The module is Q-SEE™-compliant, allowing for direct thumbnail monitoring when installed in an Ethernet-equipped 6800+ frame.
