About Dante
Overview
This product features Dante technology as a protocol to
transmit audio signals. Dante is a network protocol
developed by Audinate. It is designed to deliver multi-
channel audio signals at various sampling and bit rates,
as well as device control signals over a Giga-bit Ethernet
(GbE) network. Dante also offers the following benefits:
• It transmits up to 512 in/512 out, for a maximum total of
1024 audio channels over a GbE network. (The NUAGE
I/O series can be accommodate up to eight devices,
128 in/128 out with a 24-bit resolution on a NUAGE
system.)
• Dante-enabled devices will automatically configure their
network interfaces and find each other on the network.
You can label Dante devices and their audio channels
with names that make sense to you.
• Dante uses high accuracy network synchronization
standards to achieve sample-accurate playback with
extremely low latency and jitter.
• Dante supports redundant connections via primary and
secondary circuits to defend against unforeseen
difficulties.
By taking advantages of these benefits, you can skip any
complicated procedures to automate connections and
setups of Dante-enabled devices, remotely control I/O
racks or amplifiers from a mixing console, or make multi-
track recordings to a DAW, such as Nuendo, installed on a
computer in the network. Visit Audinate website for more
details on Dante.

Connection with Dante
Enabled Devices
To connect with Dante enabled devices, use a star
connection or a daisy chain connection (enabled devices
only).
Star Connection
In a star connection, each device is connected to a
central network switch. Using a GbE-compatible network
switch enables you to configure a wide-band, large-scale
network. We recommend a network switch that features
various functions to control and monitor the network (such
as Qos, the ability to assign priority to data flows — e.g.,
clock synchronization or audio transmission on certain
data circuits.)
With this topology, it is common to configure a redundant
network so that an unexpected network problem will not
affect any audio or otherwise stable communications.
Redundant Network
A redundant network consists of two circuits, a primary
circuit and a secondary circuit. Normally, the network
operates on the primary circuit. However, if the primary
connection is broken, the secondary circuit will
automatically take over communications. Therefore, using
a redundant network with a star topology would increase
communication stability relative to a daisy chain network.
Daisy Chain Connection (enabled
devices only)
A daisy chain is a wiring scheme in which multiple
devices are connected together in sequence. This
connection method is suitable for a simple system with a
small number of devices.
However, if a large number of devices are connected, the
latency value must be increased. Also, if a connection is
broken in a daisy chain network, the signal flow is
interrupted at that point and no signal will be transferred
beyond that point.
