The XMV8280-D/XMV8140-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 XMV8280-D/XMV8140-D features eight 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 XMV8280-D/

XMV8140-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.

About Dante

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, le

ave 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.
