This function is designed for live events that may have the problem of signal delay, image pause, blurred screen, or black screen.
There are automatic backup and manual backup.
As the above image shows, the machine will automatically switch to the backup signal once the main signal pauses. No black screen happens.
As the above image shows, if there is a failure of input source, we can press the TAKE key to switch to the backup signal. In this case, the LED screen will play the video in a smooth way to ensure the event’s running.
Tips: 780H supports 4 LED screen’s signal backup at the same time！
