About Dante
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 Rio 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:
• If three or more Rio units are mounted without
space in the same rack, set the fan speeds to HIGH.
• If multiple units are mounted in the same rack with
their fan speeds set to LOW, leave a 1U rack space
between every two units. Also either leave the open
spaces uncovered or install appropriate ventilating
panels to minimize the possibility of 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 Rio 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.
Recessed Installation
If you want to recess the front panel surface of the device
from the front edge of the rack, you can adjust the position
of the rack mount brackets to recess the device by 50mm or
100mm, as shown in the illustration below.
In the same way, rack mount hardware can also be attached
to the rear panel surface.
NOTE
When you install the brackets, use the same screws that
you just removed.

About Dante
Dante is a network audio protocol developed by the
Audinate. Within a Giga-bit Ethernet (GbE), Dante
delivers multi-channel audio signals at various sampling
frequencies and bit rates, as well as device control signals.
Visit the Audinate website for more details on Dante.
More information on Dante is also posted on the Yamaha
Pro Audio website:
Caution when using a network
switch
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 the following:
• When using a managed switch, turn off the EEE function
of all ports used by Dante. Do not use a switch that is
unable to turn off the EEE function.
• If using an unmanaged switch, do not use a switch that
supports the EEE function. Such switches are unable to
turn off the EEE function.
* EEE (Energy Efficient Ethernet) is a technology that reduces switch
