AVB Input Streams

The AVB streams received by the M-32 AD 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 AVDECC Controller is required. The M-32 AD Pro does not include an AVDECC 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, or 0 channels in CRF Media Clock stream format.

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

  1. Open the AVB tab in the INPUT section.

    wAD 230 2T 1

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

    w32 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 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.

    wAL 230 2T 2

  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 M-32 AD Pro can receive any input signal. 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 output on the device:

  1. Open the OUTPUT section.

    Coaxial Output

  2. Rotate the encoder to highlight the coaxial or optical MADI icon.
    "Route Signals to MADI Coaxial/Optical Output" text will be shown on the display.

  3. Press the encoder to open the routing. The cursor will highlight the first available channel block.

  4. Either rotate the encoder to select the next available channel block or press it to start assigning the source signal.

  5. Again, rotate the encoder to select the source for the selected output.
    Choosing "not routed" deletes an existing routing, and "cancel" aborts the routing and keeps the previous routing.

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.
