Use the MTX Editor to update the firmware of the XMV or
check the firmware version. For operation details, refer to the
“MTX Editor User’s Manual.”
You can download the latest firmware from the “Downloads”
page on the following website.

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.
