Abstract:
An acoustical control apparatus for regulating output voltage flow comprising:a power supply for providing voltages to components of said apparatus; a level control network for receiving a voltage from said power supply and receiving an audio signal from an audio signal source and providing an amplified audio signal; a multiple active filter network for receiving a voltage from said power supply and said amplified audio signal, for separating said amplified audio signal into a plurality of distinct bandwidths, and for providing regulated voltage flow from and in synchronization with said power supply at said distinct bandwidths; a phase control network receiving a voltage from said power supply and providing modulated voltage; comparators for receiving a voltage from said power supply, for receiving distinct bandwidth signals from said multiple active filter network, and for receiving modulated voltage from said phase control network, said comparators feeding triac drivers that drive control gates each time the comparators change state thereby allowing pulsating voltages; and an output control receiving a voltage from said power supply and audio signals at said plurality of distinct bandwidths from said comparators for amplifying said pulsating voltages and exporting said pulsating voltages to a plurality of output sockets.
