The Decora volume-control system consists of an advanced interface module and all-digital rocker-style volume control that replaces conventional transformer-based rotary volume controls. The control connects to the interface module using an ordinary RJ-45 data patchcord. Because speaker wiring and amplifier wiring are not connected directly to the volume control units, the system is simple to install and wire and easy to relocate when user requirements change.
