Yamaha’s unwavering approach to live sound reinforcement is wholly inherited in the Rio3224-D2 and Rio1608-D2 I/O Racks, allowing the on-stage sound to be cleanly captured and then shaped as required by the engineer. Analog circuitry developed for the first-generation Rio3224-D and Rio1608-D I/O Racks has been revised to deliver sound that represents another evolution in Yamaha’s “natural sound” concept, and overall performance that is truly worthy of “RIVAGE PM series” status.

Audinate’s Dante network protocol offers extensive flexibility for system setup and configuration. With Dante, you have the freedom to use just about any combination of devices that suits the application, and to position those devices wherever they will be most convenient. It also allows for redundancy that can keep the system running even if a problem occurs. Then there’s the Dante Controller software application for easy, flexible patching of devices on the network. In addition to supporting the AES67 standard for audio over IP interoperability, Dante offers other valuable facilities such as Dante Device Lock to prevent unauthorized operation, and the Dante Domain Manager for efficient user authentication and role-based security.* * Visit the Audinate website for more Dante Domain Manager information.

Power failure is a major risk when operating any audio I/O device. Both the Rio3224-D2 and Rio1608-D2 I/O Racks include dual power supply units to reduce the chance that power loss will result in downtime during a show. If a problem occurs with one power source, operation will continue unaffected as long as the second power source is active. Internal airflow has been redesigned too, reducing fan noise for notably quieter operation.

Another Rio3224-D2 and Rio1608-D2 refinement is the provision of character/icon displays rather than basic LED indicators, allowing quick, easy confirmation of Dante settings as well as metering, gain, high-pass filters, phantom power, and more. It is also possible to edit gain, high-pass filters, and phantom power settings directly from the I/O Rack interface, and even lock them if required. Remote operation from the R Remote software application is also possible.

gain changes, the results can be unpredictable and usually undesirable. The Rio3224-D2 and Rio1608-D2 feature a Gain Compensation function that automatically adjusts gain at the digital stage to compensate for analog gain changes, ensuring that sound is sent to the network at a constant level.
