3-3. Precautions for rack 

mounting

This unit is rated for operation at ambient temperatures 
ranging from 0 to 40 degrees Celsius. If you mount this 
unit along with other MMP1 unit(s) or other device(s) in an 
EIA standard equipment rack, temperatures inside the 
rack may rise, possibly resulting in impaired performance.
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 1U space or more between the MMP1 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 cannot be left open, install a 
commercially-available fan or similar ventilating option to 
ensure sufficient airflow. If you have 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.

3-4. Power supply

3-4-1. Connecting the AC power cord

1.

Make sure that the 

P

 [MAIN] power switch 

and the 

P

 [BACKUP] power switch are in the 

standby position (

N

).

2.

Connect the supplied power cord to the AC 
power input socket of the unit.

3.

Connect the other end of power cord to an AC 
outlet.

NOTE

•

To disconnect the power cord, 
remove the cable in the order of 
steps 1 



 3 



 2 in the procedure 

described above. 

•

To disconnect the power cord, 
remove it while holding down the 
latch on the plug.

WARNING

Use only the supplied AC power cord. Using other 
cables may lead to overheating or electric shock.

CAUTION

Be sure to set to standby the power to the unit 
before connecting or disconnecting the power 
cord.

NOTICE

Even when the power switch is in the standby position (

N

), a 

small amount of current is flowing through the unit. If you 
plan not to use the unit for a long period of time, be sure to 
remove the power cord from the AC outlet.

3-4-2. Turning the power on and set to 

standby

When you turn on the power to the unit, be sure to turn on 
the power to the power amplifiers and/or powered 
speakers last to avoid speaker damage. Before you set to 
standby the power of the unit, first turn off the power to the 
power amplifiers and/or powered speakers.

3-5. About Dante

Dante is a network audio protocol 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) network.

Visit the Audinate website for more details on Dante:

More information on Dante is also posted on the Yamaha 
Pro Audio website:

3-6. Notes regarding the use 

of network switches

Do not use the EEE functionality (*) of network switches on 
a Dante network.
Although mutual power consumption settings between 
switches that support the EEE functionality are adjusted 
automatically, there are some switches for which such 
mutual settings are not adjusted correctly.
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.

•

If you use managed switches, please disable the EEE 
functionality. Do not use switches that prevent EEE 
functionality from being disabled.

•

When using unmanaged switches, do not use switches 
that support EEE functionality. EEE functionality cannot 
be disabled for such switches.

* EEE (Energy Efficient Ethernet) is a technology that reduces 

switch power consumption during periods of low network traffic. 
It is also referred to as Green Ethernet and IEEE802.3az.

3-7. Dante network settings 

and audio routing

With the Dante network, you can route the audio input and 
output of multiple Dante devices in any way you like. This 
requires you to set which channel signals are sent to 
which inputs.
Use Dante Controller to configure the audio routing of the 
Dante network.

You can download Dante Controller from the following

Refer to the Dante Controller owner’s manual (available 
from the same website) for details about Dante Controller.
