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. See AVB Network Latency for details on AVB latency.
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. The possible states of the color indicator bar of each output stream are the following:
Description | Indicator | Possible solution |
---|---|---|
Disabled |
grey |
Create routing |
Disabled |
orange |
Create connection with AVDECC controller |
Streaming/Transmitting |
green |
|
SR mismatch |
red |
Verify that the sample rates of talker and listener are identical |
Waiting |
yellow … |
Wait for listener to be ready |
Listener Fail |
red |
Verify proper listener configuration |
No Bandwidth |
red |
Use faster network speed (1 GBit/s instead of 100 MBit/s) |
Domain Boundary |
red |
Reconnect all devices and reboot switch |
Internal Error |
red |
Reboot device |
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.
-
Select the configuration of the corresponding AVB Stream tab in the OUTPUT section.
-
Use the button next to Stream format
-
Rotate the encoder to configure a new stream size and stream format and confirm by pressing the encoder again.
-
Connect the device by USB or network cable and open the web remote.
-
Open one of the outgoing AVB Ports.
-
Select the configuration within the AVB output port to open the outgoing stream settings.
-
Adjust output streams as necessary and click OK.
Changing a stream size briefly interrupts all outgoing AVB streams. |
