4 AoIP Streaming (via SFP)
The two RAVENNA/AES67 interfaces connect the AoIP streams to the IP network.
By default, 32 stereo streams are transmitted and received via port A, while port B remains unused. The
streams are fully compatible with the SMPTE ST2110-30/31, AES67 and RAVENNA standards. Optionally, you
can use both interfaces (A and B) to support redundant streaming via SMPTE ST2022-7, Seamless Protection
Switching. This requires some modification of the streaming configuration and a supporting network
infrastructure.
The connection(s) must be made via a network switch and not directly to another streaming port. You can find
more details about the data network requirements and suitable components in the
The streaming network must be properly configured and managed. i.e. it must use a suitable network
architecture; all components must support multicast (as opposed to unicast); a proper Quality of Service
(QoS) must be configured; and so on.
Please DO NOT attempt to connect the streaming ports using an unqualifying IP network, as correct
operation cannot be guaranteed.
To use each port, you must fit a Lawo-certified SFP module (as described earlier). The SFP determines the
cable type, maximum distance and connector.
Internally, the 32 stereo Rx streams are named RAV 1 to 32 in the available sources list. A number of Tx
streams are also pre-defined; their default audio assignments are listed in the
Setting Up RAVENNA/AES67
5 MADI (via SFP)
In the ruby standard configuration, MADI ports 3 and 4 are not configured for external use.
MADI ports 1 (and 2) can be used to connect multi-channel digital audio to the system. The ports conform to
AES10 and carry 64 bi-directional channels (at 48kHz).
The two ports operate as a main and redundant connection: MADI 1 is the primary port and MADI 2 is the
redundant port. On the input side, the system will switch automatically to the redundant port if the primary port
fails. On the output side, the two ports carry duplicate signals. If redundancy is not required, then it is
recommended to connect your device port 1 and leave port 2 unconnected.
All MADI connections must be point-to-point. To use each port, you must fit a Lawo-certified SFP module (as
described earlier). The SFP determines the cable type, maximum distance and connector.
Internally, the 64 MADI channels are configured for stereo operation within the available sources
matrix. This is important to remember when assigning audio onto the 64 mono channels in the connecting
device. For example, the stereo source "MADI 2" will use the audio arriving on channels 3&4; the stereo output
named "MADI 3" will send audio out on channels 5&6; and so on.
