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 M-32 AD Pro sends
different audio signals on both ports.
10.2. AVB Output Streams
The AVB streams
leaving
the M-32 AD Pro 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 M-32 AD Pro 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 M-32
AD Pro does not include an AVDECC controller.
Outgoing AVB streams are monitored by the device as follows:
Description
Indicator
Possible solution
Disabled
grey
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
10.2.1. Change AVB Output Stream Size
Each of the four AVB streams can have a size of 4, 8, 12 or 16 channels.
To change the amount of channels in the outgoing AVB stream on the device:
1. Open one of the four
AVB
tabs in the
OUTPUT
section.
2. Move the cursor to highlight the current
AVB Stream Size
and press the encoder.
3. Rotate the encoder to configure a new stream size and confirm by pressing the encoder again.
To change the amount of channels of the outgoing AVB stream:
1. Connect to the device remotely (
see:
Section 8.5.1, “Finding the Device on a Network”).
