Introduction
Thank you for choosing the Yamaha RMio64-D audio 
interface.
To take full advantage of the superior functions and 
performance offered by the RMio64-D, and to enjoy 
years of trouble-free use, be sure to read this owner’s 
manual carefully before operation.
Features
The RMio64-D is a digital interface that lets you transfer 
up to 64 digital inputs and 64 digital outputs between a 
Dante network and a MADI-compatible device. By 
connecting both Dante and MADI, this product can be 
used for wide variety of applications such as 
broadcasting, live recording, and post production. In 
addition, full control of this unit’s settings has been 
achieved through tight integration with Yamaha’s Dante 
compatible devices.
• Supports redundancy for both Dante and MADI, and provides a high level of reliability.
• Sampling rate converter (SRC) in MADI inputs and  outputs.
• Signals can be looped back from MADI optical to  coaxial, or from coaxial to optical (MADI split).
• Enhanced linkage functionality with Steinberg  Nuendo, such as direct monitoring and high-precision 
clock sync with Nuendo SyncStation.
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 RMio 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 genera te a significant amount of 
heat, leave more than 1U of space between the RMio 
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 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.

different ID for each device. Make sure to change the 
settings of the rotary switch while the power to the 
unit is turned off; otherwise, the ID setting will not be 
effective.
 Dante DIP switches
Used to change unit settings. Make sure to change 
the settings of the DIP switches while the power to 
the unit is turned off; otherwise, the ID setting will not 
be effective. For details, see “Connecting Dante-
compatible Devices” (page 11) and “Restoring 
Factory Settings” (page 18).
	[SYSTEM LINK OUT] connector
This BNC connector is used to connect to the AES 2 
IN connector on the Steinb erg Nuendo SyncStation. 
This connection provides a highly precise clock sync 
between this unit and Nuendo.
When not connecting with N uendo SyncStation, two 
of the channels for the Dante input signals are output 
as AES/EBU signals. Connecting the AES/EBU-
compatible devices to this connector allows Dante 
signals to be converted to AES/EBU signals and can 
be output. In the default settings, Dante channels 1 
and 2 are used for output. You can use a remote 
control to change the output channels. For details, 
see “Remote Control” (page 16).
 [WORD CLOCK OUT] connector
[WORD CLOCK IN] connector
These are BNC connectors used to transmit and 
receive word clock signals.
#MADI DIP switches
Used to change unit settings. Make sure to change 
the settings of the DIP switches while the power to 
the unit is turned off; otherwise, the ID setting will not 
be effective. For details, see “Connecting MADI-
compatible Devices” (page 12) and “MADI Split” 
(page 14).
$MADI [WCLK IN FOR SRC] connector
This is a BNC connector that  can be used to directly 
input word clock signals for MADI SRC.
% MADI [COAXIAL OUT] connector
MADI [COAXIAL IN] connector
These are BNC connectors used to connect with 
MADI-compatible devices.
NOTE
Coaxial cables of up to 100 meters (theoretical value) can 
be used.
&MADI [OPTICAL OUT] connector
MADI [OPTICAL IN] connector
These are SC connectors used to connect with 
MADI-compatible devices.
NOTE
• Use a multimode optical cable with 50-micron core/125-
micron cladding diameters,  or 62.5-micron core/125-
micron cladding diameters.
• Optical cables of up to 2,000 meters (theoretical value)  can be used.
• Use SC duplex connectors.
• Attach the supplied rubber cap to the connector to  prevent dust from collecting when the cable is not 
connected.
LINK/ACT These indicators flash rapidly if the 
Ethernet cables are connected properly.
1G These indicators are lit when the Dante  network is functioning as Giga-bit 
Ethernet.
