DCH-2000AV Audio/Video 1+1 Redundancy Switch


DCH-2000AV is an 1+1 analog baseband audio/video redundancy switch. Three groups of independent 1+1 switch are implemented in a single 1RU chassis. Each switch has 1 primary audio/video input port, 1 backup audio/video input port and 2 audio/video output ports in mirror. The primary port is automatically switched to the back-up port in case of primary port failure by using built-in analog video signal quality monitor. The change-over condition is the detection of consecutive synchronization of analog TV signal. DCH-2000AV uses RF Relay switch to ensure reliable transition from primary to secondary input port in the case. With its high performance and stability, DCH-2000AV is an ideal product for broadcast system redundancy.
