Digital audio inputs and outputs over IP Dante™
(Ports for primary and secondary networks)
MIMO7272DN allows the reception of 64
channels of digital audio Dante™ and the
sending of 64
channels of digital audio Dante™ through an Ethernet network compatibl
e
with the transport of digital audio over IP through the Dante™ protocol.
The routing of the digital audio signals Dante™ through the Ethernet network, as well as
the network configuration of the ports Dante™ (IP addresses, mask, etc.) of the
MIMO7272DN,
is managed by the software application Dante™ Controller. For more
information, please refer to the developer's documentation:

MIMO7272DN features two ports with RJ45 interface in its rear panel that allow the
sending and reception of digital audio Dante™,
labelled as primary (PRIMARY) and
secondary (SECONDARY). MIMO7272DN can work with these ports in two possible
modes:
•
Redundant Mode
: there are two simultaneous network connections (each with its
own IP address, both different) so that the information Ethernet packets Dante™
are transmitted via both connections. Each port (primary and secondary) must be
connected to a different physical Ethernet local network, or to a different virtual
local network (VLAN), correctly configured and isolated from each other. The
digital audio Dante™ is therefore sent and received using two distinct and
independent paths, with no possible communication between the primary and
secondary ports. In case one of them fails, MIMO7272DN will automatically switch
to the other, recovering the audio transmission almost instantaneously. Obviously,
to achieve total redundancy, all Dante™ devices that are part of a sys
tem of this
type must have primary and secondary Dante™ ports, connected respectively to
the same two independent networks as MIMO7272DN.
