receives the AES3-A stream from the master port number 1. Set
in repeater mode, this amplier relays the AES3-A signal to the
third amplier in the chain via the RJ45 port number 2. This setup
is repeated until the nal amplier in the chain receives its AES3-A
signal. The rst connection to the Ethernet network is done via
a CAT-5 cable inserted in any free RJ45 port ( FIGURE 53 shows
port number 3 being used, but ports 2 or 4 could have been used
instead. In FIGURE 54 the only free port is port number 2). The
control data stream, travelling using the Ethernet standard, travels
within the chain alongside the AES3-A stream in a bidirectional
manner.
The daisy chain topology is not robust. If any single AES3 or
Ethernet cable connection is interrupted, the whole system fails.
In the diagram below, if the crossed out connection should fail,
both ampliers number 3 as well as 4 would not be able to receive
any audio signal to play. Their connection to the Ethernet network
would fail as well.

Intermediate audio robust chain
A slightly more robust network with respect to the audio system
is the one illustrated in the following diagram. In this connection,
two ampliers, the rst and the last one in the network, are set to
work in forward mode. The remaining “central ampliers” are set
to work in repeater mode.

The fourth amplier’s audio input is the AES3 stream coming from
the XLR connector because it is in forward mode; the AES3-A
stream coming from amplier number 3 via master port 1 is
redundant, meaning it is not necessary for the fourth amplier to
produce sound. The reason for this connection is to improve the
robustness of the audio connection of ampliers 2 and 3.
The system’s connections could be interrupted in the following
ways:
