Here’s how it works. Dual mix engines are synchronized in real-time. A high-frequency “heartbeat” between mirrored primary and backup mix engines detects the slightest change and triggers an instantaneous failover to the backup unit for rapid recovery and seamless, uninterrupted service in the event of a failure. Because the backup is synchronized with the main unit in real-time, failover is immediate (less than a half second, hardly detected as an interruption) – unlike failing over to a hot standby, which causes an interruption in service while switching to the backup. 

With this, WheatNet IP audio networked facilities can seamlessly switch to a duplicate console mix engine for continuous operation during an emergency. Active and standby unit statuses are clearly displayed in WheatNet IP NAVIGATOR management software, with manual failover options available for controlled transitions during upgrades or maintenance.

We’re getting to the heart of what it means to have a fail-safe AoIP in an always-on operation by combining failover redundancy within the network on console mix engines and across the network with hitless path redundancy on I/O Blade 4s. We will be demonstrating Blade 4 I/O hitless path redundancy as well as console mix engine failover redundancy at booth C1051 during the NAB show.
