About Dante
Dante model
 Outline of Dante
The DZR-D and DXS-XLF-D feature not only analog input/output signals, but also Dante
technology to transmit digital audio signals. Dante is a network audio protocol developed
by Audinate. It is designed to deliver multi-channel audio signals at various sampling fre-
quencies and bit rates as well as device control signals in the same network, over a Giga-
bit Ethernet (GbE) network.

 Connections
There are two ways to connect the DZR-D and DXS-XLF-D to a Dante network. Both
devices can be used in combination with one another.
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.
If you connect a large number of devices, you must set a higher latency value to avoid
audio glitches that could be caused by an increased delay in signal transfer among the
devices. Also, if a connection is broken in a daisy chain network, the signal flow is inter-
rupted at that point and no signal will be transferred beyond that point.
In a star network, 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—for example, clock
synchronization or audio transmission on certain circuits).
DZR-D and DXS-XLF-D cannot be used in a redundant (secondary) network because the
two Dante jacks of DZR-D and DXS-XLF-D are primary connectors.
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.
