ABSTRACT:
A digital potentiometer adapted for and connected to and interacting directly with a plurality of external switches. Specifically, the various wiper points of a semiconductor resistor array are selected, for each channel of an audio amplification device according to various switch selections. The method and apparatus disclosed also makes priority determinations if more than one external switch is selected at the same time according to which switch was selected first.
