An integrated cinema amplifier comprises a power supply stage that distributes power over a plurality of channels for rendering immersive audio content in a surround sound listening environment. The amplifier automatically detects maximum and net power availability and requirements based on audio content by decoding audio metadata and dynamically adjusts gains to each channel or sets of channels based on content and operational/environmental conditions. A power supply stage provides power to drive a plurality of channels corresponding to speaker feeds to a plurality of speakers. The amplifier has a front panel having an LED array with each LED associated with a respective channel or group of channels of the multi-channel amplifier, and a control unit configured to light the LEDs according to display patterns based on operating status or error conditions of the amplifier.

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.
