Abstract
There is provided an automatic gain control circuit for volume control receiving at least one audio signal input via either a wired connection or a wireless connection. The circuit includes an output signal regulator receiving a first portion of the at least one audio signal input, with the regulator being able to vary an amplitude of the first portion of the at least one audio signal input when a control signal from a circuit controller is received. The circuit controller may be powered by a DC generator; with the DC generator receiving a second portion of the at least one audio signal input. A signal from the output signal regulator may be passed through an acoustic generator. It is preferable that the first portion of the at least one audio signal input is substantially more than the second portion. It is also preferable that the output signal regulator varies the amplitude of the at least one audio signal input by reducing the amplitude. A corresponding method of volume control is also disclosed.
