About Dante
The XMV8280-D/XMV8140-D units feature Dante technology as a protocol to transmit audio signals. Dante is a network protocol developed by Audinate. It is designed to deliver multichannel 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 (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 secondary 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.
Visit Audinate website for more details on Dante.
http://www.audinate.com/
More information on Dante is also posted on the Yamaha Pro Audio website:
http://www.yamahaproaudio.com/
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.
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 panels 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.

If the switch is in the upward position and the [POWER] indicator is flashing, the unit is in standby mode.
CAUTION
•To ensure that high-volume noise is not output from the speakers, power-on the equipment starting with the audio sources, then the mixer and processors (such as the MTX), and finally the amplifiers. Reverse this order when turning the system off.
•Rapidly turning the power switch ON and OFF in succession can cause the unit to malfunction. After turning the power switch OFF, wait for about 5 seconds before turning it ON again.
•If you modified parameter settings, do not turn the power switch OFF for at least one second. Otherwise, the changes to the settings may be lost.
•Even when the power switch is turned off, a small amount of current is flowing through the unit. If you plan not to use the unit for a long period of time, remove the power cable from the AC outlet.
w[PROTECTION] A–H indicators
When the protection system is active, the indicator will light orange. If the audio output is muted, turn off the power and wait for the XMV to cool before turning the power on again. The protection circuit will operate and the [PROTECTION] indicator will light in the following situations.

Controls and Functions
When overcurrent is detected
If for any reason the impedance falls below the specification for the mode, the speaker output is muted to prevent overcurrent; muting will be cancelled after approximately one second. If overcurrent is detected after muting is cancelled, the output will be muted again.
If DC output is detected
The power supply section will be shut down.
If excessive total current or maximum current is detected
The output signal will be lowered.
e[LIMIT] A–H indicators
When the limiter operates, the speaker output will be limited and the indicator will light red. Lower the attenuator value so that the limiter does not activate, referring to “Changing the attenuator setting” (page 20). The limiter will operate in the following situations.
•When an instantaneous input overload is detected
•When an input overload has been occurring for a specific duration
•When the heat sink of the amplifier section exceeds the allowable temperature
r[SIGNAL] A–H indicators
The [SIGNAL] indicator will light in green when the input/ output signal level exceeds a certain level.
