Yamaha Rio1608-D2 I/O Rack

Dante-ready I/O Racks with Enhanced Sound, Reliability, and Displays

The Yamaha Rio3224-D2 and Rio1608-D2 are high-performance I/O Rack units with built-in Dante audio networking. Designed and manufactured to achieve outstanding sonic transparency in keeping with Yamaha’s “natural sound” philosophy, they play a vital role in supporting the performance capabilities of the associated console, offer extensive freedom for placement and multi-unit combinations, and allow redundancy for high reliability. The Rio3224-D2 and Rio1608-D2 are not only standard components of the RIVAGE PM7 Digital Mixing System, but are also fully compatible with CL and QL series digital mixing consoles, offering excellent audio and operational performance that makes the most of Dante networking potential.

The Rio1608-D2 I/O rack features 16 analog inputs and 8 analog outputs, and is compatible with Yamaha CL and QL series consoles as well as the RIVAGE PM series. The Rio1608-D2 connects directly to Dante digital audio networks, allowing flexible system configuration. Dual power supply units are built in for high reliability, and a character/graphic display offers easy visual confirmation.
