Leader LT 4440 Changeover

The Leader LT 4440 Changeover automatically switches the connection from the primary signal to the secondary back up line in case of problems with the primary signal. These signals include HD-SDI (channels 1 to 6 only), SD-SDI, AES/EBU digital audio, analog black burst signal, and tri-level sync signals. A total of 11 channels (including primary and back up signals) can be supported. When coupled with the LT 4400 Multiformat Video Generator, it can help detect problems on its primary line.
