The Calrec Audio over IP unit provides a Hydra2 AoIP interface carrying up to 512 x 512 channels using AES67/ Ravenna and or AVB modules.
The unit can accommodate two modules AoIP 1 & AoIP 2 and may be fitted with one or two 256 x 256 channel AES67/ Ravenna or AVB modules, or one of each type as required.
In addition to the standard Hydra2 redundancy each module also has both a primary and secondary 1GB IP connection, supporting hitless switching for redundancy.
IP Stream management is achieved through a WEB UI.
Hydra2 network connections
A pair of rear mounted SFP slots provide primary and secondary connections back to routers in a Hydra2 network.
Primary and Secondary SFP slots are also provided for the 2 x AoIP ports and indicators are provided on the rear to show which modules have been fitted to the unit.
The AoIP unit must be given an ID which is unique on the network, before being connected. The ID is a value from 1 to 256, set as a binary representation using DIP switches accessible from the rear.
The AES sync O/P on the rear of the unit provides a PTP clock reference derived from the Internet stream. Note: this sync O/P is not yet enabled as of 01/09/16.
The System OK LED strobes every second to indicate that the system is actively talking to the AoIP modules and the Hydra 2 interface. or every 100ms if the Hydra 2 interface is not active.
A Cat 5e connector on the front of the unit is used for Setup via a WEB UI.
