Automatic Change Over with Audio / Video Monitoring

Interact with this product in a Layout Tool:

The 570ACO-X19-25G is an auto clean switch designed for auto failover of SMPTE ST 2110 signals due to video faults, audio faults or data faults with selectable priority for each input signal. The 570ACO-X19-25G App A contains three independent cores with 2x SMPTE ST 2110 inputs (A, B) and 570ACO-X19-25G App B contains two independent cores with 3x SMPTE ST 2110 inputs (A, B,C), each capable of producing 2x SMPTE ST 2110 outputs (Program and Preview).

Monitoring capabilities include the ability to detect HD/SDI errors. Parameters include frozen video detection, black video detection, picture and audio level monitoring as well as ancillary data monitoring. Many of these parameters have user-adjustable thresholds and time periods to suit any application.


  • SMPTE ST 2022-7 on all ST 2110 main / backup inputs
  • Configurable frame delay up to 14 frames per video path (audio and ANC follow video)
  • Support slipless mode to auto- sync videos from different inputs
  • Program and Preview outputs can be manually overridden by customer to select any input
  • Clean video switch, no TRS violations on video output
  • Quiet audio switch, no pops
  • Full in-band control support for MAGNUM routing
  • VGPI support from MAGNUM
  • Priority setting for input failover
  • Can force disable an input to exclude it
  • Revertible / non-revertible failover
  • A fault reported can be included or excluded in the failover decision-making
  • Can function 3x1, 3x2, 2x2 and 2x1 ACS by disabling unused inputs / outputs
