Introduction
Thank you for choosing the Yamaha Input Rack Ri8-D/
Output Rack Ro8-D.
The Ri8-D is a Dante-compatible input rack equipped with
8 channels analog input. The Ro8-D is a Dante-compatible
output rack equipped with 8 channels analog output.
To take full advantage of the superior functions and
performance offered by the Ri8-D/Ro8-D, and to extend
the useful life of the product, be sure to read this owner’s
manual carefully before operation.
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
Ri8-D/Ro8-D 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.
Vast variety of layout is available with
compact 1U chassis
The Ri8-D is dedicated for input rack and the Ro8-D is for
output. This enables an installation of rack for an occasion
requires input only or output only.
Of course, combination with the Rio3224-D/Rio1608-D
(input/output rack) is enabled to realize system
configuration with higher flexibility.
Remotely Controllable Internal Head
Amplifiers (Ri8-D only)
Internal head amplifier parameters can be remotely
controlled from a compatible device.
Gain Compensation Function
(Ri8-D only)
Enabling Gain Compensation feature of the Ri8-D for
supporting equipment with gain compensation capability
such as CL Series products may compensate change of
analog gain in downstream by the compensation gain
integrated in the Ri8-D, and it will send the audio signal to
Dante network with gain level fixed to a value immediately
before it was enabled.
Direct Audio In/Out With a Connected
Computer
Connecting the Ri8-D/Ro8-D 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 (the Ri8-D
is for input and the Ro8-D is for output only).
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 firmware
• Dante module firmware
You must update each type of firmware separately.
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 Ri8-D/Ro8-D.
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 Ri8-D/Ro8-D 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 generate a significant
amount of heat, leave more than 1U of space
between the Ri8-D/Ro8-D 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.
