1. An apparatus for receiving an audio signal via a network, the apparatus comprising:
- a housing;
a powerline module located in the housing, the powerline module comprising;
a powerline magnetics module configured to provide isolation between a powerline physical layer (PHY) module and a high voltage powerline, the powerline magnetics module coupling a powerline signal onto the powerline PHY module, anda signal processing module configured to demodulate a received signal in orthogonal frequency division multiplexing (OFDM) format into a combined signal;
a receiver module configured to extract a control signal and an audio signal from the converted combined signal, the receiver module manipulating the audio signal based on the extracted control signal;
a plug coupled to the housing and configured for insertion into an electrical receptacle; and
a power supply configured to distribute electrical energy to the receiver module.

Abstract
A method and system for communicating audio signals between an input device and an output device via a network. The output device can include loudspeakers and headphones. In some embodiments an output device, for example a center channel speaker, transmits audio signals to other output devices. In some embodiments, the output device is coupled to, or combined with, a speaker stand or speaker bracket. The network can be wireless, wired, infrared, RF, and powerline.
