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 networks.
• Connecting a computer to Dante network using an
Ethernet connection enables you to directly input or
output audio signals without using any audio interface
devices.
• Audio can be transferred over distances up to 100
meters* between devices using CAT5e network cables.
* Maximum practical distance may vary
according to the cable used.
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
devices from a mixing console; or make multi-track
recordings to a DAW, such as Nuendo, installed on a
computer in the network.

NOTE
Please do not use the EEE function (*) of network switches
in a Dante network.
Although power management should be negotiated
automatically in switches that support EEE, some switches
do not perform the negotiation properly. This may cause
EEE to be enabled in Dante networks when it is not
appropriate, resulting in poor synchronization performance
and occasional dropouts.
Therefore we strongly recommend that:
• If you use managed switches, ensure that they allow EEE
to be disabled. Make sure that EEE is disabled on all ports
used for real-time Dante traffic.
• If you use unmanaged switches, make sure to not use
network switches that support the EEE function, since
EEE operation cannot be disabled in these switches.
* EEE (Energy Efficient Ethernet) is a technology that
reduces switch power consumption during periods of
low network traffic. It is also known as Green Ethernet
and IEEE802.3az.
About Dante Controller
Dante Controller is a software application that allows
configuration and audio routing of Dante networks. Use
this application if you plan to connect or set up
Dante-enabled devices (such as Dante-MY16-AUD) that
do not feature CL native support, or if you wish to set up
complicated signal routings on a Dante network. More
information is posted on the following website.
http://www.yamahaproaudio.com/
To run Dante Controller, a computer must feature a
GbE-compatible Ethernet connector.
Refer to the Dante Controller owner's manual for details on
Dante Controller.

Connecting to I/O devices

This section explains how to connect the CL series to I/O
devices (such as RIO3224-D) in a daisy chain network and
in a star network (redundant network). Before you make
connections with I/O devices, perform the steps described
in "Setting up the Dante network" (see page 40), and then
turn off the power of the CL series unit.
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.
