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 12Mic sends different audio
signals on both ports.
10.4. AVB Output Streams
The AVB streams
leaving
the 12Mic 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
.
The output streams of the 12Mic 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 12Mic
does not include an AVDECC controller.
Outgoing AVB streams are monitored by the device as follows:

10.4.1. Change AVB Output Stream Size and Format
Each of the eight outgoing AVB streams can have a size of 1-8, 12 or 16 channels in AM824 and AAF
stream formats, or 0 channels in CRF Media Clock stream format.
To change the amount of channels and its format in the outgoing AVB stream on the device:
1. Select the configuration
of the corresponding
AVB Stream
tab in the
OUTPUT
section.
