R Series (AD/DA)I/O Rack

The “natural, musical sound” that was a key element of the CL Series design policy is carried on without compromise in the R Series. Mechanical construction, circuit board layout, power supply, grounding, and parts selection have all been executed with meticulous attention to detail and quality, combined with exhaustive performance and listening tests at each stage of development. The result is eminently natural, musical sound.

The Dante network audio protocol developed by Audinate offers outstanding system scalability and flexibility. The required number of audio inputs and outputs can be placed wherever they are needed most, and the ability to implement redundant connections makes it possible to design a system that will keep going in the face of technical problems. With CL Series components a complete daisy-chained system can be easily set up without the need for network switches. Dante Controller software running on a personal computer allows flexible patching of devices on the network.

CL Series components are not the only Yamaha professional audio devices that will work with R Series I/O racks. With the Dante-MY16-AUD Mini-YGDAI card from Audinate installed, the M7CL, LS9, DME64N, and other compatible Yamaha pro audio gear can be used with Rio Series devices in capable and robust Dante network systems. The Rio3224-D, Rio1608-D, and Ri8-D head amplifiers can even be controlled directly from the interface of the M7CL, LS9, or other compatible console.

When multiple consoles are connected to one I/O rack and operators at those consoles make analog gain changes, the results can be unpredictable and usually undesirable. The Rio3224-D and Rio1608-D 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.

In addition to the Rio3224-D and Rio1608-D models that were released together with the CL Series consoles, input-only Ri8-D and output-only Ro8-D models are now available, making up a four-model lineup that reinforces the underlying Rio Series concept: “the number of inputs and outputs you need, wherever you need them.” The Ri8-D can be used as a portable input rack, and the Ro8-D can be used for output in an amp room, for example. The possibilities are extensive, making it easy to optimally match systems of any size or complexity.

R Series I/O units work just as well with Dante-capable devices such as a NEXO NXAMP equipped with the NXDT104 card as they do with CL Series consoles. Discovery and patching for the Rio I/O and NXAMP can be managed directly from the CL console without the need for a computer and Dante Controller software.

The Rio3224-D handles stage-side I/O, while Ri8-D units serve as a portable input racks on stage and at the console position. An Ro8-D is located in the hall’s or theater’s amp room, delivering audio to the system’s power amplifiers.

Rio Series I/O units can be used with a PM5D console and DME64N digital mixing engine to create a 96 kHz system. Rio input signals are mixed at the PM5D, and then returned to the Rio units after processing via the DME64N. Even relatively complex routing like this can be easily managed via simple physical cabling and virtual patching via the Dante Controller software.

* The PM5D and DME64N must be equipped with the Audinate Dante-MY16-AUD interface card.

* The Dante Controller software is required to set up to allow Rio Series head amplifier control from the PM5D console.
