Introduction
Thank you for choosing the Yamaha Rio3224-D/Rio1608-D 
I/O Rack. The Rio3224-D is a Dante-compatible I/O rack, 
featuring 32 analog inputs, 16 analog outputs, and 8 
AES/EBU outputs. The Rio1608-D is a Dante-compatible 
I/O rack, featuring16 analog inputs and 8 analog outputs. 
To take full advantage of the superior functions and 
performance offered by the Rio3224-D/Rio1608-D, and to 
extend the useful life of the product, be sure to read this 
owner’s manual carefully before operation.
NOTE
• Where specifications for the Rio3224-D differ from the 
Rio1608-D, this manual places  specifications that apply 
only to the Rio1608-D in curly brackets {  } (e.g., [INPUT] 
connectors 1-32 {1-16}).
• Unless otherwise noted, illu strations for the Rio3224-D are 
used.
• If certain specifications ar e common to both the Rio3224-D 
and Rio1608-D, both units are collectively called “Rio.”
Features
Long-distance Dante Network Capability
Low-latency, low-jitter audio can be transferred over 
distances up to 100 meters* between devices via standard 
Ethernet cables using the Dante network protocol. The Rio 
can be used as a general-purpose I/O box for the Dante 
network. Supported sampling rates are 44.1 kHz, 48 kHz, 
88.2 kHz, and 96 kHz.
* Maximum practical distance may vary according to the cable used.
Remotely Controllable Internal Head 
Amplifiers
Internal head amplifier parameters can be remotely 
controlled from a compatible device, such as the CL series, 
or from a computer application “R Remote.”
Digital Outputs (Rio3224-D only)
The Rio3224-D features XLR-3-32 type balanced 
connectors for AES/EBU format digital audio outputs.
Gain Compensation Function
If the Rio’s Gain Compensation function is enabled from a 
supported device that lets you set gain compensation (such 
as CL series products), the subsequent fluctuations in 
analog gain will be compensated for by internal digital 
gain. The audio signal will be output to a Dante network 
with a gain level that was fixed immediately before the Gain 
Compensation function was enabled. In this way, you can 
set the gain individually for FOH and MONITOR even if 
they share the same channel.
Direct Audio In/Out With a Connected 
Computer
Connecting the Rio with a standard Ethernet cable to a 
computer that has a Dante Virtual Soundcard installed 
enables you to directly input or output audio signals 
without using an audio interface device.
Firmware Updates
This product enables you to update the unit firmware to 
improve operations, add functions, and correct possible 
malfunctions. The following two types of firmware are 
available for the unit.
• Unit’s f ir mware
• Dante module firmware
Details on updating the firmware are available on the 
following website: http://www.yamahaproaudio.com/
For information on updating and setting up the unit, please 
refer to the firmware update guide available on the website.
NOTE
When you update Dante firmware on the unit, be sure to 
update Dante firmware on other Dante-compatible devices 
connected to the Rio.
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  t h e r a c k m ou nt br a cket s  to  re c e ss  t he  d e v ic e by  5 0 m m  or 
100mm, as shown in the illustration below.
NOTE
When you install the brackets, use the same screws that 
you just removed.
About Dante
This product features Dante technology as a protocol to 
transmit audio signals. Dante is a network 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. Dante also offers the following 
benefits:
•It transmits up to 512 in/512 out, for a total 1024 
channels (in theory) of audio over a GbE network. 
(The Rio3224-D features 32 in/24 out with a 24/32-bit 
resolution. The Rio1608-D features 16 in/8 out 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. Five types of latency are 
available on the Rio: 0.25 msec, 0.5 msec, 1.0 msec, 
2.0 msec, and 5.0 msec.
• Dante supports redundant connections via primary and 
secondary networks to defend against unforeseen 
difficulties.
• Connecting a computer to Dante network over Ethernet 
enables you to directly input or output audio signals 
without using any audio interface devices.
By taking advantages of these benefits, you can skip any 
complicated procedures to automate connections and 
setups of Dante-enabled devices, remotely control I/O 
racks or amplifiers from a mixing console, or make 
multi-track recordings to a DAW, such as Nuendo, installed 
on a computer in the network.
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 synchronizat ion 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.

Controls and Functions
Front Panel
1[INPUT] Connectors 1–32 {1–16}
These are the XLR-3-31 type analog balanced 
connectors for the input channels. The input level 
range is from –62 dBu to +10 dBu. +48V phantom 
power can be supplied to devices that require it via the 
input connectors.
NOTE
The PAD will be switched on or off internally when the gain 
of the internal head amp is adjusted between +17 dB and 
+18 dB. Keep in mind that noise may be generated if there 
is a difference between the Hot and Cold impedance of the 
external device connected to the INPUT connector when 
using phantom power.
2[+48V] Indicators
These indicators light when +48V phantom power is 
turned ON for the corresponding input channels. 
Phantom power supply switching can be carried out 
from a compatible digital mixing console or computer 
application. No phantom power will be supplied, 
however, if the [+48V MASTER] switch is OFF, even 
if phantom power to individual channels is turned ON 
(the +48V indicators will flash). The +48V indicators 
also function as error indicators: the indicators for all 
channels will flash if an error occurs.
CAUTIONS:
• Make sure that phantom power is turned OFF unless it is 
needed.
• When turning phantom power ON, make sure that no 
equipment other than phantom-powered devices such as 
condenser microphones are connected to the 
corresponding [INPUT] connectors. Applying phantom 
power to a device that does not require phantom power can 
damage the connected device.
• Do not connect or disconnect a device to an INPUT while 
phantom power is applied. Doing so can damage the 
connected device and/or the unit itself. •
To prevent possible damage to speakers, make sure that 
power amplifiers and/or powered speakers are turned OFF 
when switching phantom power ON or OFF. We also 
recommend setting all digita l mixing console output 
controls to minimum when turning phantom power ON or 
OFF. Sudden high level peaks caused by the switching 
operation can damage equipment as well as the hearing of 
those present.
3[SIG] (Signal) Indicators
These indicators light green when the signal applied 
to the corresponding channel reaches or exceeds 
–34 dBFS.
The SIG indicators also function as error indicators: 
the indicators for all channels will flash if an error 
occurs.
4[PEAK] Indicators
These indicators light red when the signal level of the 
corresponding channel reaches or exceeds –3 dBFS.
The PEAK indicators also function as error 
indicators: the indicators for all channels will flash if 
an error occurs.
5[UNIT ID] Rotary Switch
This rotary switch enables you to set an ID number so 
that connected devices will recognize the Rio. The 
UNIT ID must be a unique number in the network so 
that the Rio will be able to transmit and receive audio 
signals over a Dante network, or be controlled from a 
connected digital mixing console.
Use the rotary switch while the power to the unit is 
turned OFF. Otherwise, the ID setting will not be 
effective.

6DIP Switches
These switches enable you to specify the settings 
related to the startup operation of the unit.
Set the DIP switches while the power to the unit is 
turned OFF. Otherwise, the setting will not be 
effective.
Refer to the following for details.
The switch illustrations indicate the setting state as 
follows.
• Switch 1 (UNIT ID) This switch setting determines whether the 
hexadecimal setting of the [UNIT ID] rotary switch 
will range from 0 to F or from 10 to 1F.
• Switches 2 and 3 (IP SELECT MODE) These specify the method of setting the IP address 
used when communicating with an external device 
such as R Remote. When connecting the R series to a 
computer for the first time immediately after 
purchase, set this to something other than STATIC IP 
(MANUAL). If you want to set this to STATIC IP 
(MANUAL), first specify the IP address from R 
Remote and then switch this setting to STATIC IP 
(MANUAL).  • Switch 4 (SECONDARY PORT)
This switch setting determines whether the rear-panel 
[SECONDARY] connector will be used for a daisy 
chain or redundant network.
With the [DAISY CHAIN] setting, you can connect 
multiple Dante-enabled network devices in a daisy 
chain without using a network switch. Refer to “Daisy 
Chain Network” in the “About Connections” section 
(see page 13) for more information about daisy chain 
connections.
With the [REDUNDANT] setting, the [PRIMARY] 
connector will be used for primary connections, and 
the [SECONDARY] connector will be used for 
secondary (backup) connections. If the unit is unable 
to transmit signals through the [PRIMARY] 
connector for some reason (e.g., due to damage or 
accidental removal of the cable, or a failed network 
switch), the [SECONDARY] connector will 
automatically take over communications and 
functions on the redundant network. Refer to “About 
Redundant Networks” in the “About Connections” 
section (see page 13) for more information on 
redundant networks.

Description
DAISY CHAIN The [SECONDARY]  connector is used for a 
daisy chain connection. A 
signal at the [PRIMARY] 
connector will be 
transmitted to the next 
device in the chain as is.
REDUNDANT The [SECONDARY]  connector is used for a 
redundant network. It will 
function as backup 
connection, independent of 
the network to which the 
[PRIMARY] connector is 
connected.
