1. An apparatus for receiving an audio signal via a powerline network, the apparatus comprising:
- a housing;
a powerline module located in the housing, the power line module comprising;
a frequency converting module configured to convert a powerline signal of an intermediate frequency, received via a powerline network, into a baseband signal;
an A/D converting module configured to convert the baseband signal into a digital signal;
a signal processing module configured to convert the digital signal into a combined signal; and
a powerline magnetics module configured to provide isolation between the powerline network and the frequency converting module, the frequency converting module operating on a substantially lower voltage than the powerline network;
a receiver module located in the housing and 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;
a power supply in the housing, coupled to the plug and configured to distribute electrical energy to the receiver module; and
an output wire configured to couple the housing to an output device.

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.
