About Dante
The XMV4280-D/XMV4140-D units feature Dante technology
as a protocol to transmit audio signals. Dante is a network pro-
tocol 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) net-
work. Dante also offers the following benefits:
• It transmits up to 512 in/512 out, for a total 1024 channels
(theoretically) of audio over a GbE network.
(The XMV4280-D/XMV4140-D features four inputs 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 available on the XMV4280-D/
XMV4140-D: 0.25 msec, 0.5 msec, 1.0 msec, and 5.0 msec.)
• Dante supports redundant connections via primary and sec-
ondary circuits to defend against unforeseen difficulties.
• Connecting a Dante-enabled device to a computer over
Ethernet enables you to directly input or output audio signals
without using any audio interface devices.

NOTE
Please do not use the EEE function (*) of network switches in a
Dante network.
Although power management should be negotiated automati-
cally in switches that support EEE, some switches do not per-
form the negotiation properly.
This may cause EEE to be enabled in Dante networks when it
is not appropriate, resulting in poor synchronization perfor-
mance 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 net-
work 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.

Precautions for Rack Mounting
This unit is rated for operation at ambient temperatures
ranging from 0 to 40 degrees Celsius. When mounting
the unit with other XMV unit(s) or other device(s) in an
EIA standard equipment rack, internal temperatures can
exceed the specified upper limit, resulting in impaired
performance or failure. When rack mounting the unit,
always observe the following requirements to avoid heat
buildup:
• When mounting the unit in a rack with devices such as
power amplifiers that generate a significant amount of
heat, leave more than 1U of space between the XMV
and other equipment. Also either leave the open
spaces uncovered or install appropriate ventilating pan-
els to minimize the possibility of heat buildup.
• To ensure sufficient airflow, leave the rear of the rack
open and position it at least 10 centimeters from walls
or other surfaces. If the rear of the rack can't be left
open, install a commercially available fan or similar
ventilating option to secure sufficient airflow. If you've
installed a fan kit, there may be cases in which closing
the rear of the rack will produce a greater cooling effect.
Refer to the rack and/or fan unit manual for details.
