Abstract
A system and method for controlling the volume output of speakers comprising outputting a varying volume control signal in response to movement of a volume control element. In response to the volume control signal, increasing a volume level of a speaker in a linear correlation with the movement of the volume control element as the volume control element is moved between a first position and a second position. In response to the volume control element moving beyond the second position, increasing the volume level of the speaker to increase asymptotically as the volume control element is moved beyond the second position. Additionally, a visual indicator, such as LED lights, provides an interesting and informative display as the volume level is changed.
