Forward to AES3-B:
the amplier behaves just as in the “forward to AES3-A” mode
but with respect to the AES3-B stream. The AES3 stream coming
from the rear panel Phoenix connector will be routed to the
AES3-B stream on both RJ45 ports 1 and 2. The AES3-A stream,
if present will be repeated from/to RJ45 ports 1 and 2.

Forward to both:
the amplier’s rear panel AES input via the Phoenix connector will
be routed to both AES3 stream A and AES3 stream B on both
main ports 1 and 2. Repeater functionality will be disabled.

IMPORTANT: when an amplier is set to forward the Phoenix
AES3 signal to either the AES3-A or AES3-B stream, the
amplier can accept as the sole AES3 input signal the one coming
from the Phoenix connector. The RJ45 ports cannot, when the
amplier is in forwarding mode on both streams, input an AES3
signal to the amplier.
9.2 Network robustness
Duecanali Series ampliers equipped with a KAESOP are capable
of being connected each to the other via a network: using a single
sound source, each amplier in the network can be, for example,
dedicated to providing power audio signal to a given subsection
of a large venue. In dealing with networks of ampliers, one of
the most important aspects to consider, especially when working
in a critical application such as large venue sound distribution, is
the robustness of the network itself. Data and audio connections
can be made “fault proof”: this means that if for some reason
one audio or data connection should fail, the whole system is not
compromised. The degree of redundancy expresses how many
network connections can break before sound is interrupted in
any one amplier part of the system. A “zero degree” redundant
system is not robust: the rst connection to jump (either from a
cable failure or even from an amplier problem) means the whole
system goes down. A “one degree” redundancy system, on the
other hand, will continue working automatically if one (but no
more than one) connection fails. This happens because Duecanali
Series ampliers can sense a connection failure and automatically
(and almost instantaneously) invert the audio feed direction to
allow the source signal to remain uninterrupted.
The following section illustrates and analyzes some common
amplier networks divided by redundancy degrees.

ampliers.
