A system, particularly adaptable for lighting and music presentations, such as for mood, ambience, or party settings includes a flat, wireless broadcast multi-point, synchronizable and scalable operation. The system includes a control system having an electronic circuit which includes a wireless mesh radio, a microcontroller, a wireless short-range radio link unit, a plurality of field-effect transistor (FET) drivers to connect to one or more individual light or sound producing devices or sets thereof, a low voltage DC power supply, an audio input rectifier and filter, and a rotary switch. The system is set up such that a plurality of these control systems are interconnected in a non-hierarchical mesh network, wherein the mesh wireless radio of a given control system has the capacity to signal other nearby control systems.
