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 Ri8-D features 8 in with a 24/32-bit resolution.
The Ro8-D features 8 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. Five types of latency are
available on the Ri8-D/Ro8-D: 0.25 msec, 0.5 msec,
1.0 msec, 2.0 msec, and 5.0 msec.
• Dante supports redundant connections via primary and
secondary networks to defend against unforeseen
difficulties.
• Connecting a computer to Dante network over Ethernet
enables you to directly input or output audio signals
without using any audio interface devices.
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.

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.
