7620PX
Changeover Unit

The 1 RU standalone 7620PX changeover unit is the complement of the 7600HD-REF reference and test signal generator. It provides active monitoring and switching of reference and test signal input pairs. Each signal pair has a primary and secondary input feeding a switching output. The unit includes battery backup and local and remote alarm alerts for power loss.

  • Two triple-switching relay modules monitor sync pulse and color burst for six independent signal pairs, such as blackburst, tri-level sync, analog video and other test signals
  • Two dedicated blackburst monitoring and changeover switches
  • One dedicated HD/SD-SDI monitoring and changeover switch with battery backup
  • Two AES/EBU monitor and changeover switches (balanced or unbalanced)
  • Manual or automatic changeover with delay management for preventing switching on glitches
  • Robust operation with simple local configuration and control, including LED status display
  • GPI interface for remote control and monitoring
  • Two hours of backup battery in case of power failure for powering the internal alarm and providing power to the SDI monitoring/changeover module
  • Switching to main inputs by default in case of power failure
