A Yamaha Rio3224‑D is a digital stage box that serves as the connection point between microphones, instruments, and a Yamaha digital mixing system. Instead of running large analog snakes across a venue, the Rio allows audio signals to be sent over a Dante network using a single network cable, simplifying setup while reducing cable bulk and improving system flexibility. Commonly paired with Yamaha CL, QL, and other Dante‑enabled consoles, it makes it possible to place inputs and outputs exactly where they are needed on stage while keeping the mix position located elsewhere in the venue. As a result, the Rio3224‑D has become a staple of professional concert, corporate, broadcast, and house‑of‑worship audio systems.
