The DV-321 is an HD/SD Sync Generator with a genlock input. The genlock input accepts tri-level or bi-level signals. The DV-321 provides four HD sync outputs. These outputs produce an HD tri-level sync output. Eighteen HD output formats are supported on the DV-321. Also provided are two SD composite sync outputs that can be switched between color black or color bars. An AES11 output and a Wordclock output are also standard features of the DV-321. The AES11 output may be switched between silent and tone modes. All outputs are provided on rear panel BNC connectors. Front panel dip switches allow the user to configure the various outputs.
