The Yamaha 1608-D is a member of the R (Rio) Series of Dante-networked audio stage boxes, designed to provide high-quality, flexible remote input/output (I/O) for Yamaha's CL, QL, and Rivage series digital mixing consoles, as well as any other Dante-enabled audio system. This compact, rugged unit serves as a critical interface between analog audio sources—such as microphones, instruments, and line-level signals—and a digital audio network, effectively extending the console's I/O capacity to the stage or any remote location. It houses 16 premium microphone preamps on Neutrik XLR/TRS combo inputs, along with 8 balanced analog XLR outputs, all accessible over a single Ethernet cable carrying power, audio, and control data via the Dante protocol.

A key feature of the Rio series is the inclusion of Yamaha's renowned headroom-rich, low-noise preamplifiers, which deliver transparent audio quality suitable for the most demanding professional applications. The 1608-D integrates seamlessly into Dante networks, appearing as a standard Dante device that can be easily routed to and from any other Dante endpoint, such as a console, recorder, or processor. It supports primary and secondary Dante ports for network redundancy, ensuring audio continuity in mission-critical live events. The unit is also powered via Power over Ethernet (PoE+), significantly simplifying installation by eliminating the need for a separate AC power cable at the stage box location.

Built for the rigors of touring and fixed installation, the 1608-D features a robust steel chassis, a clear metering display for input and output levels, and redundant power supply options. Its compact form factor makes it easy to mount on a microphone stand, place on a stage, or install in a rack. By providing remote, network-based I/O with studio-grade preamps, the Yamaha 1608-D dramatically reduces analog cable runs, increases system flexibility, and forms the foundation of a scalable, future-proof audio infrastructure for live sound, broadcasting, and installed sound applications.
