AVB Input Streams

The AVB streams received by the M-1620 Pro 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 ATDECC Controller is required. The M-1620 Pro does not include an ATDECC Controller.

AVB input streams are monitored as follows:

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.

To change the amount of channels and format of incoming AVB streams on the device:

  1. Open the AVB tab in the INPUT section.

    w162 230 2T 1

  2. Move the cursor to highlight the corresponding AVB stream size and press the encoder.

    w162 230 2T 3

  3. Rotate the encoder to configure a new stream size and format, then confirm by pressing the encoder again.

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 Remote Control Overview.

  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.

    wAL 230 2T 2

  4. Click OK wAL co 3.

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