Abstract: Embodiments include a power source outputting power to drive speakers and lights in a venue; a control unit coupled to the power source and outputting multi-channel digital audio data to the speakers and light control data to the lights; and a unitary transmission bus coupling the output of the power source to the speakers and the lights and transmitting the power, the digital audio data, and the light control data to the speakers and the lights. The lighting control data comprises metadata superimposed over the digital audio data and power. Other actuators besides lights may also be used such as e.g. steam/water generators, smell/aroma generators, prop movements, LCD displays, hologram generators, and the like.
