About Dante
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 total 1024
channels (in theory) of audio over a GbE network. (The
CL series features 64 in/64 out with a 24/32-bit
resolution.)
• 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. Four types of latency are
offered by the CL series: 0.25 msec, 0.5 msec, 1.0 msec,
and 5.0 msec.
• Dante supports resilient redundant connections against
unexpected network problems via primary and
secondary circuits.
• Connecting a Dante-enabled device to a computer using
an Ethernet connection enables you to directly input or
output audio signals without using any audio interface
devices.
By taking advantage 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.

About connections
There are two ways to connect the CL unit to a Dante
network.
■ Daisy chain network
A daisy chain is a wiring scheme in which multiple devices
are connected together in sequence. In this way,
networking is simple and requires no network switches.
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.
■ Star network
In a star network, each device is connected to a central hub.
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.
About redundant networks
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
resiliency against unexpected network problems relative to
a daisy chain network.
