AVB Input Streams

The AVB streams received by the AVB Tool are referred to as "input streams". For these streams, the device acts as an AVB Listener.

To establish a connection between a talker and a listener, an AVDECC Controller is required. The AVB Tool does not include an AVDECC Controller.

AVB input streams are monitored as follows:

Description Indicator Possible solution



Create connection with AVDECC controller



No Data


Verify proper talker configuration

SR Mismatch


Verify that the sample rates of talker and listener are identical


yellow …​

Waiting for talker to be ready

Talker Fail


Verify proper talker configuration

No Bandwidth


Use faster network speed (1 GBit/s instead of 100 MBit/s)

Domain Boundary


Reconnect all devices and reboot switch, ensure only AVB switches are used

Internal Error


Reboot device

Change AVB Input Stream Size

Each of the eight 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 format of incoming AVB streams:
  1. Open the AVB tab in the INPUT section.

  2. Use the first button and encoder to select an incoming stream.

  3. Use the second button and encoder to change the stream size and format.

To change the amount of channels of the incoming AVB streams using the web remote:
  1. Connect the device by USB or network cable and open the web remote.

  2. Open an AVB port in the routing area and use the up and down arrows wAL co 1 to adjust the stream size.

  3. Use the stream format dropdown wAL co 2 to select the format to be used.

  4. Click Apply.

Changing a stream size briefly interrupts all incoming AVB streams.
Incoming streams can contain less than the specified amount of channels.

Routing Signals to the Outputs

Each output channel of the AVB Tool can receive any input signal. If preset 1 has not been modified, it contains a routing of all analog inputs to all digital outputs. However, this can be adjusted and changed easily. The factory default preset does not contain any routing.

A routing immediately activates input monitoring for a corresponding digital input and raises a warning in the input state if the source signal is not available or out of sync.

The following example shows the procedure to route to MADI Coaxial output channels. Other outputs follow the same procedure.

To create a routing to a MADI Coaxial output:
  1. Open the routing tab of the MADI Coaxial output in the OUTPUT section (see Controlling the device).

    Coaxial Output
  2. Activate the routing destination and choose an output channel with the encoder (steps 1 and 2).

  3. Activate the routing source and choose an input channel with the encoder (steps 3 and 4).

To remove a routing:
  1. Navigate to the corresponding output channel (1, 2).

  2. Double click on "Increment routing". The routing source will be changed to "not routed".

  3. (optional) Hold "increment routing" while turning the encoder to remove routings to the following output channels.

To route consecutive channels:
  1. Navigate to the first output channel (1, 2) and create a routing as described above.

  2. Hold "increment routing" while turning the encoder clockwise to increment input channel and output channel at the same time.

To create a routing to a MADI output on the web remote:
  1. Enter the Routing mode by pressing the corresponding icon in the title bar.

  2. Click the MADI coaxial or MADI optical output port.

  3. Select individual or consecutive channels by clicking or dragging. The channels are highlighted in blue and an arrow handler is revealed.

  4. If the input ports are closed, drag the handle onto an input port, it opens automatically.

  5. Drag the handle onto the source channel strips to select a range of channels as signal source.
