AES Input Failover - Does it Monitor AES Sync?
This document explains what is monitored when using the Input Failover feature with a primary AES/EBU input.
Q: If my main (Primary) input source to the VOLT is AES/EBU, can the audio failover be configured to switch to the secondary source NOT by detecting a certain duration of silence, but simply on loss of AES/EBU sync?
A: Yes. The VOLT actually does look at the AES input sync status in the failover logic. When AES/EBU is selected as the primary input and the failover time is set to anything other than 0, loss of digital sync will cause immediate failover to the secondary input.
The failback is governed by the usual time delay. If you want to defeat the time feature of the failover and use the sync loss only, we would suggest setting "Failover Time" to a very large value. For example, the maximum 20 seconds. This is probably enough to make sure it never triggers accidentally. The failover will still occur immediately on loss of AES sync; the time value does not apply to this.
