Abstract
The apparatus is a cross fader with a plurality of optocouplers wired in parallel electrical relationship with each other. A slider interrupts the light signal of at least one of the optocouplers and the resultant information is communicated to a chip which determines the position of the slider and thereby calculates the resultant mix of first and second electronic audio signals to derive a third electronic audio signal which is the output signal.
