The latency of the MADI I/O is four samples.
The M-1610 Pro creates an entirely new output signal and does not pass on any embedded
information. One exception are SysEx messages (incl. MIDI over MADI) that are passed on
between the ports chosen in the MIDI Remote settings.
10.3.3. MADI Port Mirroring
A redundant MADI connection protects from loss of audio in case of a single cable failure. To achieve
redundancy, the receiver must support MADI redundancy. The sender must send two identical MADI
signals on two outputs, usually the coaxial and optical ports.
The M-1610 Pro features independent routing for both MADI output ports. For this reason, a "mirroring"
of the signal must be manually created. In order to do this, the routing of the two MADI outputs should be
configured to contain the same routing.
The receiving device usually ignores the audio contents of the two MADI signals. Therefore,
the redundancy may appear to be set up even though the M-1610 Pro sends different audio
signals on both ports. Always ensure that the routing is correct for both output ports.
10.4. AVB Output Streams
The AVB streams leaving the M-1610 Pro are described as "output streams". In this case, the device acts
as a talker. The talker defines the presentation time and therefore the latency across the network. This is
set per default to 2 ms. See Section 5.4, "AVB Network Latency" for details on AVB latency.
The output streams of the M-1610 Pro are by default empty, containing a clock signal but no audio
signal. To send audio with AVB, a routing must be created for each outgoing stream.
To establish a connection between a talker and a listener, an AVDECC controller is required. The M-1610
Pro does not include an AVDECC controller.
Outgoing AVB streams are monitored by the device. The possible states of the color indicator bar of
each output stream are the following:
