Abstract
Embodiments are described for a hybrid amplification architecture that separates individual audio amplifier stages from the power supply and a simple two- or three-conductor bus that transmits both power and audio signal to a plurality of daisy-chained speakers to playback adaptive audio content in an expanded surround-sound environment including surround and overhead speakers or for use within professional live sound applications and/or distributed audio systems. A control unit generates digital audio and power and transmits both simultaneously over the bus to individual speaker units associated with each speaker. The speaker units recover the power decode the channel assignment to route the audio to the appropriate speakers.
