The VB273 provides full dual-path redundancy with autonomous operation and deep signal analysis on both signal paths for unprecedented switching decision making. Front panel controls with innovative illuminated signal path visualization and light illuminated buttons give local control and excellent visual overview of switching operations. Local autonomous operation, remote control by NMS and/or triggers in addition to a Super Local mode for complete local override makes it suitable for any real-life operational challenges. The VB273 INTELLIGENT REDUNDANCY SWITCH has multiple layers of redundancy, from the VB300 dual power AC chassis to magnetically latched broadcast-grade signal relays to protect against any contingency, even a complete power loss and also to provide component upgrade or swaps without signal interruption. The VB273 card provides 2 inputs of post modulator signals and one output for the transmit stage.
