Yamaha Ro8-D Ri8-D/Ro8-D Owners Manual [English] - Page 8

Introduction 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, such as the CL series, or from a computer application "R Remote." 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 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. 8 Owner's Manual
