Abstract: An embedded computing device which receives and buffers one or more digital audio streams provided by wired or wireless devices such as computers, tablets and smart phones via a network. The streams are buffered to allow for delays and irregularities in the rate at which these streams are delivered. The streams are then distributed to a series of digital amplifiers while allowing each amplifier to play a chosen source at a volume level that is selected by a user. This embodiment reduces the number of required electronic components, delivers high quality audio because the system is entirely digital from source through amplification, and is energy efficient thereby minimizing the generation of waste heat. In addition, the invention allows for features such as limiting the volume for certain users, or for certain zones during specified periods of time, as well as features to diagnose and/or compensate for installation errors or problems.
