AES3 (AES/EBU) is getting more and more popular. It seems to be simple to incorporate AES3 interface to devices owing to its digital advantages, however, we are constantly improving our AES3 Input module. In order to reduce jitter, we use asynchronous sample rate converter for synchronisation. Bi-stable relays are used for ground lifting as they need only very short voltage impulse on coil to change the swich state, which enables reducing electromagnetic interference to the signal. The signal input is galvanically isolated. The module has a self-diagnostic feature to prevent unwanted outage before it happens. It is compatible with all Base boxes and consoles of G series.
