High Definition Distributed Sound System
First Claim
1. A high definition distributed sound system comprising:
- a master control hub having a plurality of serially linkable zones;
at least one serial array of powered speakers; and
a Cat5 cable;
one zone of said plurality of serially linkable zones having an audio input, an internal master level controller and at least one powered-speaker output; and
each of said at least one serial array of powered speakers being connected to a corresponding one of said at least one powered-speaker outputs by said Cat5 cable.

Abstract
A high definition distributed sound system has a master control hub with multiple serially linkable zones each capable of handling multiple serial arrays of powered speakers and a Cat5 cable. Each zone has an audio input, an internal master level controller and multiple powered-speaker outputs. Each of the serial arrays of powered speakers are connected to a corresponding powered-speaker output by the Cat5 cable. All of the zones can be used and controlled independently of the others or any number of them can be serially linked and controlled by their preceding zones. Additional master control hubs can be serially linked in a single system. The system interconnections can be done with Cat5 cable using RJ45 connectors. A low idle current power amplifier circuit offers extremely low levels of quiescent current, allowing a large number of speakers to be connected in one system.

18. A high definition distributed sound system comprising a Cat5 cable delivering power and audio signals to at least one serial array of powered speakers with a low quiescent current amplifier limiting current consumption of each active speaker of said at least one serial array of speakers to less than 100 milliamps.
