The ADVC-HDSC1 can be used as a sync generator in compact facilities like houses of worship and corporate spaces. It outputs HD and SD references and provides easy configuration of standards through its front panel display. The ADVC-HDSC1 was used to provide sync signals to a Grass Valley Kayak production switcher and associated equipment, as well as to monitor embedded audio from the Kayak recorder. Its compact size and integrated features make it suitable for sync generation and audio monitoring in portable Kayak applications.
