Intercom Connection
-
Connect your existing intercom party line(s) to one (or both) Intercom Ch 1&2 XLR connectors of the NSA-003A.
-
The female intercom connection A/B is internally looped through to the corresponding male intercom connection A/B, to connect additional devices to the Partyline.
AES67 Network Connection
-
Connect the primary media network port (ETH 1 / Primary) to your AES67 network.
-
For redundant operation, also connect the secondary media network port (ETH 2 / Secondary) to your AES67 network.
Power Supply
The NSA-003A is powered exclusively via PoE (IEEE 802.3bt) through the primary and secondary media network ports.
The device's power supply has a redundant design and switches over without interruption as soon as one of the power sources is no longer available. The primary connection has priority over the secondary connection. The NSA-003A PoE device supports MPS (Maintain Power Signature) to prevent the redundant PoE connection (in idle mode) from being switched off by the PoE switch.
The PoE status can be checked via the web interface.
-
For redundancy, both network ports are connected to two separate PoE switches.
-
To shut down the unit completely, remove both Ethernet cables.
