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:
If the connection between ampliers 2 and 3 should fail, the
Ethernet network connection would be interrupted but not
the audio stream. As a result of the interruption of the amplier
2-amplier 3 link, amplier number 3 would stop receiving an
incoming AES3 stream from amplier number 2; amplier number
4, however, would continue forwarding the AES3 stream into
amplier 3. This means that amplier 3 would automatically sensea
backup AES3 feed coming from amplier 4.

FIGURE 51: If the connection between ampliers number 2 and
3 should fail, amplier number 4 forwards a backup AES3 stream
towards amplier number 3 so no audio interruption can be heard.
If the connection between ampliers 1 and 2 should fail, no
sound interruption would be heard. In this case, amplier number
4 would still forward its AES3 stream direction to amplier 3.
Ampliers 3 would invert its repeater stream and feed the
AES3 stream to amplier number 2. Amplier number 2 would
therefore be able to continue to reproduce the AES3 stream this
time coming from amplier number 3 instead of amplier number
1. Amplier number 1 reproduces sound from the Phoenix rear
panel AES3 source.

FIGURE 52: If the connection between ampliers number 1 and 2
should fail, ampliers number 4 and 3 would automatically act as a
backup AES3 stream that can reach amplier number 2 so no audio
interruption can be heard.
The Ethernet network, however, would still be compromised.
If the connection between amplier number 3 and 4 should fail, no
audio interruption would be heard. Amplier number 3 receives
its incoming AES3 stream from amplier number 2. The fourth
amplier reproduces sound coming directly from the AES3 source
fed in its rear panel Phoenix connector.
The robustness of this network is guaranteed for AES3 signals only,
and for a single cable failure at a time. If two or more connections
should fail, one or more ampliers (depending on where the
interruption occurs) would be muted.

Intermediate data robust chain
The audio signal robustness of the previous intermediate chain
example is guaranteed by the double AES3 forward mode of the
top and bottom ampliers in the chain. The same cane be done for
the Ethernet data connection, using an external switch capable of
managing two (and more) Ethernet streams. The diagram below
shows this conguration for Duecanali ampliers.
