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.
Key Features
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
Specifications
Standard Configuration Two triple-switching relay boards providing:
