Videotek VSX-11D

The VSX-11D is a highly versatile, multi-format autochangeover unit designed for use with a wide array of reference signals and offering a high degree of protection during primary reference signal loss. TheVSX-11D will accommodate standard-definition and high-definition SDI signals (HD/SD SDI), NTSC/PAL blackburst, Tri-level Sync, and AES/EBU audio. The VSX-11D is the ideal autochanger for use with the SPG-1601. The VSX-11D provides 11 channels with user-selectable configuration. Each channel has a primary and backup input with a common output. All of the 11 channels are available for high-definition serial digital (HD SDI) operation. Channel configuration is set via an internal DIP switch. The VSX-11D can be manually switched or automatically switch all channels to the backup source on a detected fault of any primary source. In addition, each input can be monitored for fault levels and switch automatically on detection of a fault. When faults are detected in both the primary and backup inputs switching will not occur. Switching is by mechanical relay with all channels switched simultaneously. Front panel includes status indicators for each of the 22 input sources, source selection, panel lock, operational controls for automatic or manual operation and resetting of fault conditions.
