Abstract
When an audio distribution system is installed, it is normally required to install wiring between the audio source or sources, and all of the speakers that are installed throughout a building or structure. The installation of this wiring is normally time consuming and difficult, and can be a large cost component of the system installation. Therefore, there is a need for an audio distribution system that makes use of, and takes a benefit from, already installed electrical power wiring, or allows a lesser number of wires to be run where new installations are necessary, through the means of upgrading the system to provide uninterrupted power to the powered speakers while maintaining the ability to control lighting fixtures powered through the same wiring infrastructure.
